Hassen JY, Debella A, Eyeberu A, Mussa I. Prevalence and concentration of aflatoxin M 1 in breast milk in Africa: a meta-analysis and implication for the interface of agriculture and health. Sci Rep 2024; 14:16611. [PMID: 39025909 PMCID: PMC11258143 DOI: 10.1038/s41598-024-59534-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 04/11/2024] [Indexed: 07/20/2024] Open
Abstract
Breast milk is one of the many distinct forms of food that can be contaminated with aflatoxin M1 (AFM1). They may be consumed by eating contaminated foods, such as contaminated meat and crops, which would then be present in breast milk and cause health problems, including nervous system disorders and cancers of the lungs, liver, kidneys, and urinary tract. However, the prevalently inconsistent explanation of prevalence and concentration remains a big challenge. Thus, this meta-analysis was conducted to determine the prevalence and concentration of harmful chemicals in breast milk in an African context. The databases MEDLINE, PubMed, Embase, SCOPUS, Web of Science, and Google Scholar were searched for both published and unpublished research. To conduct the analysis, the collected data were exported to Stata version 18. The results were shown using a forest plot and a prevalence with a 95% confidence interval (CI) using the random-effects model. The Cochrane chi-square (I2) statistics were used to measure the studies' heterogeneity, and Egger's intercept was used to measure publication bias. This review included twenty-eight studies with 4016 breast milk samples and newborns. The analysis showed the overall prevalence and concentration of aflatoxin M1 in breast milk were 53% (95% CI 40, 65; i2 = 98.26%; P = 0.001). The pooled mean aflatoxin M1 concentration in breast milk was 93.02 ng/l. According to this study, the eastern region of Africa was 62% (95% CI 39-82) profoundly affected as compared to other regions of the continent. In subgroup analysis by publication year, the highest level of exposure to aflatoxins (68%; 95% CI 47-85) was observed among studies published from 2010 to 2019. This finding confirmed that more than half of lactating women's breast milk was contaminated with aflatoxin M1 in Africa. The pooled mean aflatoxin M1 concentration in breast milk was 93.02 ng/l. According to this study, the eastern region of Africa was profoundly affected compared with other regions. Thus, the government and all stakeholders must instigate policies that mitigate the toxicity of aflatoxins in lactating women, fetuses, and newborns.

Abstract
The human microbiome exhibits a profound connection with the cancer development, progression, and therapeutic response, with particular emphasis on its components of the mycobiome, which are still in the early stages of research. In this review, we comprehensively summarize cancer-related symbiotic and pathogenic fungal genera. The intricate mechanisms through which fungi impact cancer as an integral member of both gut and tissue-resident microbiomes are further discussed. In addition, we shed light on the pivotal physiological roles of various nutrients, including cholesterol, carbohydrates, proteins and minerals, in facilitating the growth, reproduction, and invasive pathogenesis of the fungi. While our exploration of the interplay between nutrients and cancer, mediated by the mycobiome, is ongoing, the current findings have yet to yield conclusive results. Thus, delving into the relationship between nutrients and fungal pathogenesis in cancer development and progression would provide valuable insights into anticancer therapy and foster precision nutrition and individualized treatments that target fungi from bench to bedside.

Correlations of Aflatoxin Exposure from Cooking Oil and Dietary Foods During Pregnancy with Birth Weight and Gestational Age at Birth in Guangxi, China. Int J Gen Med 2024; 17:1171-1184. [PMID: 38562209 PMCID: PMC10982453 DOI: 10.2147/ijgm.s453839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 03/02/2024] [Indexed: 04/04/2024] Open
Abstract
Background Cooking oil and dietary foods are easily contaminated by aflatoxins (AFs) in Guangxi, China where low birth weight and preterm birth were prevalent. However, there are no data on AF exposure in pregnant women or their impact on newborn birth outcomes. This study aims to measure the levels and correlations of AFs in cooking oil, estimated dietary intake (EDI) of AFs in dietary foods, and serum AFB1 albumin adducts (AFB1-alb) with newborn birthweight and gestational age at birth. Methods A prospective study was conducted among 126 pregnant women in Guangxi, China. All recruited women were interviewed for demographic data and behavior and obstetric information and then followed up until giving birth. AF measurements were obtained from cooking oil, dietary foods, maternal serum, and cord blood and the correlations of AF levels with newborn birthweight and gestational age at birth were tested using correlation analysis. Results The median EDI of AFs in cooking oil was 2.61 ng/kg.bw/day and in dietary foods 2.95 ng/kg.bw/day. High positive correlations among EDI of aflatoxin B1 (AFB1) from cooking oil and dietary foods were found (r > 0.7). Low positive correlations of AFB1-alb in maternal serum and cord blood and both EDI of AFB1 in both cooking oil and dietary foods were shown (r ≈0.3). Significant correlations between AF levels in both cooking oil and dietary foods with birth weight were found, but very low negative correlations (r = - 0.244 ~ -0.285). AFB1 levels in foods, maternal serum and cord blood levels were high in pregnant women with newborn low birth weight and preterm birth. Conclusion The EDIs of AFB1 from both cooking oil and dietary foods were significantly correlated with AFB1-alb in maternal serum and cord blood. Negative correlations of AFs from cooking oils and foods with newborn birth weight should be paid more attention.

Determination and risk assessment of aflatoxin B1 in the kernel of imported raw hazelnuts from Eastern Azerbaijan Province of Iran. Sci Rep 2024; 14:6864. [PMID: 38514765 PMCID: PMC10957946 DOI: 10.1038/s41598-024-57422-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 03/18/2024] [Indexed: 03/23/2024] Open
Abstract
Aflatoxin B1 (AFB1) is widespread and seriously threatens public health worldwide. This study aimed to investigate AFB1 in imported hazelnut samples in northwest of Iran (Eastern Azerbaijan Province) using High-Performance Liquid Chromatography with a Fluorescent Detector (HPLC-FLD). In all tested samples AFB1 was detected. The mean concentration of AFB1 was 4.20 μg/kg and ranged from 3.145 to 8.13 μg/kg. All samples contained AFB1 levels within the maximum acceptable limit except for one sample. Furthermore, the human health risk assessment of AFB1 from consuming imported hazelnuts by Iranian children and adults was evaluated based on the margin of exposure (MoE) and quantitative liver cancer risk approaches. The MoE mean for children was 2529.76, while for adults, it was 8854.16, indicating a public health concern. The present study found that the risk of developing liver cancer among Iranian children was 0.11100736 per 100,000 people, and in the Iranian adult population was 0.0314496 cancers per 100,000 people. Since environmental conditions potentially affect aflatoxin levels in nuts, countries are advised to monitor aflatoxin contents in imported nuts, especially from countries with a conducive climate for mold growth.

Abstract
A novel analytical method based on nanofiber-packed solid-phase extraction (PFSPE) combined with HPLC-FLD has been successfully developed and applied to determine aflatoxin B1, B2, G1, G2 in foods. In order to effectively adsorb analytes from complex food matrices, four types of nanofibers based on skeleton of polystyrene-polyvinyl pyrrolidone were prepared by electrospinning and applied as adsorbent to home-made solid-phase extraction device. The effects of type of nanofibers, pH of sample, type and concentration of salt ion, type of activation solvent, type and volume of eluent, amount of nanofibers, and extraction time on the adsorption/desorption were investigated and optimized. Under optimal conditions, the method showed satisfactory linear relationship, with limits of detection (LODs) of 0.07-0.17 ng g-1, intra-day and inter-day RSDs for spiked samples of 1.3-8.0 % and 1.9-5.8 %, and absolute recoveries in the range of 60.1-98.4 %. The results presented the great potential to be utilized to determine AFs in foodstuffs.

ENVIRONMENT INTERNATIONAL 2024; 185:108537.

Abstract
This study aimed to present the occurrence of sixteen mycotoxins in 105 meat alternatives based on wheat, legumes, and vegetables from Italy. The targeted mycotoxins were aflatoxins (AFB1, AFB2, AFG1, AFG2), fumonisins B1 and B2 (FB1, FB2), alternariol (AOH), alternariol monomethyl ether (AME), tentoxin (TEN), ochratoxin A (OTA), zearalenone (ZEN), T-2/HT-2 toxin, deoxynivalenol (DON), enniatin B (ENNB), and beauvericin (BEA). The occurrence of mycotoxins was between 0% (AFB2) - 97.4% (ENNB). Mycotoxin co-occurrence varied from binary combinations up to mixtures of twelve. To assess the dietary exposure and potential health risks we simulated the replacement of meat consumption for Italian consumers with meat alternatives. The cumulative exposure to Alternaria mycotoxins and trichothecenes indicated a potential health risk while the exposure to aflatoxins and ochratoxin A indicated a potential health concern related to liver and renal cancer in the model scenario. Moreover, we estimated the risk of liver cancer from exposure to AFB1 and quantified the potential burden using Disability-Adjusted Life Years (DALYs). Luckily, the potential risk of liver cancer was low between 0 and 0.05/100,000 individuals with an associated burden of disease of 0.83 DALYs/100,000 individuals. Taking into consideration the presence of meat alternatives on the food market and the ongoing shift towards plant-based diets there is a need for continuous monitoring to keep the occurrence at safe levels. More attention is needed from the regulatory side for policymakers to consider the legislations of mycotoxins in meat alternatives.

Abstract
This paper reviews the published terminology, mathematical models, and the possible approaches used to characterise the risk of foodborne chemical hazards, particularly pesticides, metals, mycotoxins, acrylamide, and polycyclic aromatic hydrocarbons (PAHs). The results confirmed the wide variability of the nomenclature used, e.g., 28 different ways of referencing exposure, 13 of cancer risk, or 9 of slope factor. On the other hand, a total of 16 equations were identified to formulate all the risk characterisation parameters of interest. Therefore, the present study proposes a terminology and formulation for some risk characterisation parameters based on the guidelines of international organisations and the literature review. The mathematical model used for non-genotoxic hazards is a ratio in all cases. However, the authors used the probability of cancer or different ratios, such as the margin of exposure (MOE) for genotoxic hazards. For each effect studied per hazard, the non-genotoxic effect was mostly studied in pesticides (79.73%), the genotoxic effect was mostly studied in PAHs (71.15%), and both effects were mainly studied in metals (59.4%). The authors of the works reviewed generally opted for a deterministic approach, although most of those who assessed the risk for mycotoxins or the ratio and risk for acrylamide used the probabilistic approach.

Abstract
Water kefir grains (WKGs), the starter used to develop a traditional beverage named water kefir, consist of a symbiotic mixture of probiotics with diverse bioactivities, but little is known about their abilities to remove mycotoxins that have serious adverse effects on humans and animals. This study investigated the ability of WKGs to remove aflatoxin B1 (AFB1), one of the most toxic mycotoxins, under different settings, and determined the mechanism of absorption mediated by WKGs and the effect of WKGs on the toxicity induced by AFB1 and the reduction in AFB1 in cow milk and tea soups. The results showed the WKGs used herein were dominated by Lactobacillus, Acetobacter, Phenylobacterium, Sediminibacterium, Saccharomyces, Issatchenkia, and Kodamaea. HPLC analysis demonstrated that the WKGs effectively removed AFB1 at concentrations ranging from 1 to 5 µg/mL, pH values ranging from 3 to 9, and temperatures ranging from 4 to 45 °C. Additionally, the removal of AFB1 mainly depended on absorption, which was consistent with the Freundlich and pseudo-second-order kinetic models. Moreover, only 49.63% of AFB1 was released from the AFB1-WKG complex after four washes when the release of AFB1 was non-detectable. Furthermore, WKG treatment caused a dramatic reduction in the mutagenicity induced by AFB1 according to an Ames test and reduced more than 54% of AFB1 in cow milk and three tea soups. These results suggested that WKGs can act as a potential bio-absorbent with a high binding ability to detoxify AFB1 in food and feed via a chemical action step and multi-binding sites of AFB1 absorption in a wide range of scenarios.

Abstract
Aflatoxins B1 (AFB1) are fungi-produced toxins found in crops like peanuts, maize, and tree nuts. They constitute a public health concern due to their genotoxic and carcinogenic effects. A deterministic exposure risk assessment to AFB1 through the consumption of peanuts was conducted on children using the Margin of Exposure (MOE) and the liver cancer risk approaches. Data on AFB1 concentrations in peanuts, quantities of peanut consumption, and the weights of the children were obtained from the literature. Generally, MOE values were below the safe margin of 10,000, ranging between 3.68 and 0.14, 754.34 and 27.33, and 11,428.57 and 419.05 for the high (0.0466 ng/kg), median (0.00023 ng/kg), and low (0.000015 ng/kg) AFB1 concentration levels, respectively. The liver cancer risk upon lifetime exposure to highly AFB1-contaminated peanuts (0.0466 ng/kg) ranged between 1 and 23 (95% lower bound) and 2 and 50 (95% upper bound) cases in a million individuals: a public health concern. A low liver cancer risk (≤1 case in a billion individuals upon lifetime exposure) was shown at median and low AFB1 concentrations. However, the risk of AFB1 should be a priority for risk management since its harmful effects could be potentiated by poor diet, high malnutrition levels, and other disease burdens in Zambia's children.

Abstract
Aflatoxins (AFs) are frequent contaminants in crops worldwide and can cause adverse health effects in exposed humans. Since foods AFs (AFB1, AFB2, AFG1, AFG2) contamination in Sichuan Province are unexplored, we conducted a study to assess AFs exposure in the population. In total, 318 samples, including grains, red chilli, red chilli powder, and vegetable protein beverages, were collected from 13 cities of Sichuan Province, China, in 2022. AFs were detected in all types of foods except for wheat flour, the highest incidence was found in red chilli powder (75.0%). The concentrations of AFtot (the total aflatoxins) ranged between ND (not detected) and 54.20 μg kg-1. It was observed that the AFs profile was dominated by AFB1. The AFB1 content ranged from ND to 52.60 μg kg-1 across food types. According to EU maximum limits (ML) of AFs, 2.8% of samples exceeded the AFtot limits. For AFB1, 0.4% and 4.3% of samples exceeded the China and EU limits, respectively. In this study, packaging types and sampling sites were selected as parameters influence food aflatoxin contamination. Nevertheless, there was no significant difference between different samples. According to exposure assessment and risk characterization, AFtot daily exposure was shown to be 0.263 and 283.936 ng kg-1 bw for the lower and upper exposure. The MOE value derived from consumption grains and red chilli pepper products were generally bellow 10 000, and liver cancer cases based on these two foods consumption could range from < 0.001 to 0.16 cases per year/10 000 persons.

Exposure assessment of aflatoxins and zearalenone in edible vegetable oils in Shandong, China: health risks posed by mycotoxin immunotoxicity and reproductive toxicity in children. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:3743-3758.

Abstract
Human exposure to aflatoxins (AFs) and zearalenone (ZEA) has not been sufficiently investigated. Here, we analyzed the exposure level and health risks posed by AFs (B1, B2, G1, G2) and ZEA through cooking oil consumption in Shandong, China. The individual daily consumption of cooking oil was calculated through 2745 questionnaires during 2017-2019. The average contamination levels of mycotoxins were estimated by examining 60 cooking oil samples. For the peanut oil, AFs ranged from <0.2 to 274 μg/kg, with a positive rate of 66.6% (20/30). Average levels of 36.62 μg/kg AFB1 and 44.43 μg/kg total AFs were found. Over-the-limit level (20 μg/kg) of AFB1 was detected in 8/30 samples. Estimated daily intake (EDI) and margin of exposure (MOE) for age-stratified population groups showed that children are facing highest adverse health risk with AFB1 (MOE 5.88-6.39). The liver cancer incidences attributable to AFB1 exposure are non-negligible as 0.896, 0.825, and 0.767 cases per 100,000 for 6-14 age group, 15-17 age group, and adult labor-intensive workers. Over-the-limit level (60 μg/kg) ZEA contamination was detected in 25/30 corn oil samples with a 50th percentile value of 97.95 μg/kg. Our health risk assessment suggested significant health risks of enterohepatic (inflammation and cancer), reproductive, and endocrine systems posed by AFs and ZEA. However, the health risk of immunotoxicity is unclear because currently animal study data are not available for the immunotoxicity induced after long-term exposure. In general, the health risks posed by mycotoxins are non-negligible and long-term mycotoxin surveillance is necessary.

Abstract
Ochratoxin A (OTA) is a nephrotoxic and carcinogenic mycotoxin that can be found in coffee. This study aimed to obtain the processing steps commonly applied by coffee shops in Indonesia, calculate the level of OTA in coffee bean and ground coffee, and the risk estimate of OTA exposure from ground coffee in Indonesia. The processing steps were determined through an online survey while the level of OTA in coffee was calculated from available references. The consumption level of ground coffee was determined from the Indonesia total diet study report and the exposure assessment was carried out by deterministic approach. The risk estimates were expressed as % risk towards provisional tolerable weekly intake (PTWI) and margin of exposure (MOE). Based on the survey of coffee shops (n=20), ground coffee is commonly processed using dry method consisting of cherries sorting, sun drying, roasting and grinding. Ground coffee was the most common coffee consumed by adults. Based on references from countries with climate similar to Indonesia, the level of OTA in coffee bean ranged from 0.033 to 168 μg/kg with an average of 12.25 μg/kg and 0.018-55 μg/kg in ground coffee averaging at 5.60 μg/kg. The individual exposure to OTA from drinking coffee is 0.014-0.744 ng/kg bw/day. The risk estimates shows that risk of ochratoxin A from ground coffee consumption is low, with risk percentage of <100 % provisional tolerable weekly intake (PTWI) and a MOE of higher than 10000 for all age groups. The study suggested that adults (19-55 years) have higher exposure and risk than the other age groups.

Abstract
Cancer has become the leading cause of premature death in many counties in recent decades. Previous studies showed plenty of evidence that control of modifiable risk factors would reduce the cancer burden. Since modifiable risk factors could be eliminated by changing the lifestyles of individuals, a greater uptake of modifiable risk factors is critical to reducing cancer burden and inequality in cancer survival. However, climate change will widen cancer inequities through its complex connections with modifiable risk factors. In this perspective, complex connections between climate change and cancer risks via modifiable risk factors, including abnormal temperature, UV, air pollution, natural disasters, food (diet), water, infections, and inefficient physical activities, have been summarized. The associations between climate change and modifiable risk factors have no doubt expanded the inequities. People who face overlapping modifiable risk factors, but who are unable to change or adapt, are at the highest risk in the climate change-cancer linkage. Though individual actions to avoid exposure to modifiable risk factors have been recommended, limited benefits would be achieved unless the nations strive to ensure the basic needs of the people. No choice makes avoiding exposure to risk factors an empty phrase. Thus, government actions should be taken to reduce the expanded inequities in cancer risks.

Abstract
BACKGROUND Aflatoxin-contaminated grain consumption over the years has been known to result in serious health hazards for its consumers. The present study investigated the effects of harvest seasons and drying methods on aflatoxins in freshly harvested maize. A 2 × 3 × 3 × 3 × 3 factorial design was used; two harvesting seasons (dry and wet), maize varieties (P3966W, P4063W and P4226), moisture contents (0.15, 0.12, and 0.10 g kg-1 ), modern fabricated solar dryer (MFSD), hybrid biomass dryer (HBD) and open-air drying (OAD) methods, and packaging materials (plastic, jute and polyethylene bag) were studied, respectively. In total, 162 samples (n = 162) of maize grains (250 g each) were dried. The freshly harvested maize was shelled, dried, stored and analyzed for aflatoxins using high-performance liquid chromatography. The data obtained were subjected to statistical analysis. RESULTS P3966W and P4063W with an initial moisture content of (0.226 and 0.234 g kg-1 ) reached a safe level of 0.10 g kg-1 using MFSD within 2-3 days, HBD within 2-3 days and OAD within 5 days. Variety P4226 with an initial moisture content of 0.228 g kg-1 reached a safe moisture level of 0.10 g kg-1 in 2, 3, and 7 days using MFSD, HBD and OAD, respectively. Aflatoxin concentration (56.00 ± 8.89 μg kg-1 ) was highest in P4063W at 0.15 g kg-1 moisture content, which exceeded the maximum permissible limits of 4 μg kg-1 recommended by the World Health Organization. CONCLUSION Variety, type of dryer and season affect aflatoxin contamination of maize. The adoption of MFSD drastically reduced the duration of drying and consequently controlled contamination by aflatoxins. © 2022 Society of Chemical Industry.

Toxins (Basel) 2022; 14:toxins14080547. [PMID: 36006209 PMCID: PMC9415889 DOI: 10.3390/toxins14080547] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 07/07/2022] [Accepted: 07/23/2022] [Indexed: 11/16/2022] Open
Abstract
Contamination of edible oils with aflatoxins (AFs) is a universal issue due to the detrimental effects of aflatoxins on human health and the fact that edible oils are a major source of fungal growth, particularly storage fungi (Aspergillus sp.). The objective of this study was to assess aflatoxin B1 (AFB1) in edible oil used in fried food in order to determine the risk of cancer from AFB1 exposure through cooked food using the FAO/WHO’s and EFSA’s margin of exposure (MOE) quantitative liver cancer risk approaches. Using Mycosep 226 columns and HPLC-FLD, 100 samples of cooking oils (soybean, canola, and sunflower oil) from different food points were analyzed for contamination with aflatoxins. Of all the samples tested, 89% were positive for total aflatoxins and AFB1, with 65% indicating AF concentrations beyond permitted levels. Canola oil was found to contain higher levels of AFB1 and AFs than soybean and sunflower oil. Almost 71 percent of canola oil samples (range of 54.4–281.1 µg/kg) were contaminated with AF levels higher than the proposed limits of the European Union (20 µg/kg). The consumption of canola oil samples used in fried foods had MOE values that were significantly lower as compared to sunflower and soybean oils, indicating that risk reduction is feasible. Additionally, compared to soybean and sunflower oil, canola oil exhibited a greater threat of liver cancer cases linked to AFB1 exposure (17.13 per 100,000 males over 35 and 10.93 per 100,000 females over 35). Using a quantitative liver cancer approach, health risk valuation demonstrated that males and females over the age of 35 are at significant risk of developing liver cancer. The health risk assessment exposed that the males and female over the age of 35 are at considerable risk of liver cancer by using a quantitative liver cancer approach. The innovation of this study lies in the fact that no such study is reported related to liver cancer risk evaluation accompanied with AFB1 exposure from consumed edible oil. As a result, a national strategy must be developed to solve this problem so that edible oil products are subjected to severe regulatory examination.

Abstract
Liver cancer (L.C.) is the most common cause of cancer death in the United States and the fifth most common globally. The overexpression of nuclear factor E2 related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) caused by oxidative stress has been associated with tumor growth, aggressiveness, treatment resistance, and poor prognosis. Nutraceuticals that inhibit Nrf2/HO-1 signaling may become the most effective strategy to treat liver cancer. Phytochemicals found in fruits and vegetables, also known as nutraceuticals, tend to emerge as chemopreventive agents, with the added benefit of low toxicity and high nutritional values. This paper reviews the present scientific knowledge of the Nrf2/HO-1 signaling as a possible target molecule for chemotherapeutic agents, its basic control mechanisms, and Nrf2/HO-1 inducers produced from natural products that might be employed as cancer chemopreventive drugs. The growing interest in the contribution of the Nrf2/ARE/HO-1 signaling in the development of liver cancer and the Use of nutraceuticals to treat liver cancer by targeting Nrf2/ARE/HO-1. PRACTICAL APPLICATIONS: An increase in Nrf2 expression indicates that Nrf2 is the most important player in liver cancer. Cancer patients are more resistant to chemotherapy because of this erroneous Nrf2 signaling. Furthermore, an increasing body of evidence indicates that activation of the Nrf2/HO-1 pathway results in the production of phase II detoxifying and antioxidant enzymes, which serve a defense purpose in cells. As a consequence, treating liver cancer. This master regulator may be a possibility. Nutraceuticals that reduce Nrf2/HO-1 signaling may be the most effective strategy for preventing liver cancer. The methods of action of numerous natural substances are examined in this article.

Occurrence of Total Aflatoxins, Aflatoxin B 1, and Ochratoxin A in Chicken and Eggs in Some Cameroon Urban Areas and Population Dietary Exposure. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2022; 2022:5541049. [PMID: 35726322 PMCID: PMC9206572 DOI: 10.1155/2022/5541049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2021] [Revised: 02/24/2022] [Accepted: 05/27/2022] [Indexed: 11/18/2022]
Abstract
Consumption of chicken and eggs contaminated by mycotoxins could lead to a public health concern. This study was conducted to evaluate the dietary exposure of populations to aflatoxins (AFs) and ochratoxin A (OTA) through these poultry products in the three most urbanized regions of Cameroon (Centre, Littoral, and West). A survey was firstly carried out to know about the consumption frequency by the different population age groups as well as their awareness about mycotoxins. Chicken feed, broiler, and eggs were collected from modern poultry farms. AFs and OTA were analysed using the enzyme-linked immunosorbent assay (ELISA), and dietary exposure was evaluated using a deterministic approach. From the 900 households questioned, a daily consumption frequency of chicken and eggs was the most reported (41% and 69%, respectively), with populations having a very weak knowledge of mycotoxins and their associated health risk (18%). Mean concentrations of AFs, AFB1, and OTA in poultry tissues were below the established regulated limits (20 μg/kg for AFs, 10 μg/kg for AFB1, and 5 μg/kg for OTA) in feeds. These toxins were detected at average concentrations of 1800 and 966.7 ƞg/kg for AFs in chicken muscle and egg, respectively, and 1400 and 1933.3 ƞg/kg for OTA in muscle and egg, respectively. Based on the survey, their estimated daily intakes through these poultry products tended to be lower than the limits 1 and 100 ƞg/kg bw/day for AFB1 and OTA, respectively). The margins of exposure (MOE) of the different population age groups to AFB1 and OTA obtained suggest that the public health concern associated with the presence of mycotoxins in poultry products shall not be underestimated.

Abstract
Aflatoxins are mycotoxins that can contaminate grains, legumes, and oil seeds. These toxic compounds are an especially serious problem in tropical and sub-tropical climates. The objective of this study was to raise awareness of aflatoxin exposure among primary school children in Shebedino woreda, southern Ethiopia, by measuring urinary aflatoxin M1 (AFM1). The study employed a cross-sectional design and systematic random sampling of children from eight schools in the district. The mean ± SD age of the children was 9.0 ± 1.8 years. Most (84.6%) households were food insecure with 17.9% severely food insecure. Urinary AFM1 was detected in more than 93% of the children. The median [IQR] concentration of AFM1/Creat was 480 [203, 1085] pg/mg. Based on a multiple regression analysis: DDS, consumption of haricot bean or milk, source of drinking water, maternal education, and household food insecurity access scale scores were significantly associated with urinary AFM1/Creat. In conclusion, a high prevalence of urinary AFM1 was observed in this study. However, the relation between AFM1 and dietary intake was analyzed based on self-reported dietary data; hence, all of the staple foods as well as animal feeds in the study area should be assessed for aflatoxin contamination.

Abstract
Aflatoxin is one of the dangerous fungal toxins that is produced in the presence of humidity and heat and lack of proper storage conditions and is considered as a dangerous substance threatening human health. The work aimed to determination of aflatoxin M1 (AFM) level in raw, pasteurized, and sterilized milks offered in the study area and to evaluate the risk of its consumption. In this descriptive cross-sectional study, 60 samples of milk types supplied in the region were collected during two series of sampling (cold and hot seasons) and analyzed by ELISA method. LCR, MoE, and HI indices were used to assess the possible risk of consuming milk containing AFM. In all taken samples AFM was found, the toxin concentration range in the first and second series of sampling was 57.5-270.6 ng/L and 57-185.9 ng/L, respectively. The level of toxin in pasteurized and sterilized milks in both sampling series was higher than raw milks. Based on the obtained data and in order to assess the risk of milk consumption in the target population, associated values with EDI, LCR, MoE, and HI were also calculated and obtained in the range of 0.145-0.3 ng/k.d b.w, 0.0008-0.0017 additional case per one million population, 1892.9-3921.6 and 0.72-1.5 ng/kg b.w, respectively. According to the findings, all samples tested are contaminated and although it is within the range of the WHO recommendation, however, based on the calculated indicators, the risk of liver cancer threatens the consumers of these milks. Therefore, it is necessary to manage this issue through educational control and monitoring measures.

Abstract
Occurrence of mycotoxins in staple foods is a major threat to attaining food safety in developing countries. The study investigated multi-mycotoxin contamination for the first time in Nepalese maize along with the incidence of molds in 45 samples of maize used as human food from 45 districts of Nepal. The samples were analyzed quantitatively for the presence of five different mycotoxins (total aflatoxins (AF), total fumonisins (FUM), ochratoxin (OT), zearalenone (ZEA) and (DON) deoxynivalenol) using the competitive direct ELISA technique. The most frequent occurrences were for DON (100%) and AF (78%) followed by FUM and ZEA (both 76%) and OT (62%). Interestingly, all the samples contained at least two mycotoxins while at least three or more mycotoxins were found in 87% of the samples. The most commonly reported binary, ternary and quaternary combinations were DON+AF, AF+FUM+DON and AF+FUM+ZEA+DON, respectively. The mean percentage kernel mold infection was 35.33% with Fusarium, Aspergillus, Rhizopus and Penicillium genera being the predominant molds. Six different species of Aspergillus and a single species of Fusarium were identified. The estimated daily intake, margin of exposure and risk of liver cancer from consuming maize were 30.46 ng/kg bw/day and 5.58 and 0.38 cancer cases/year/100,000 population, respectively. Since maize is the second-most consumed cereal in Nepal, the contamination levels of various mycotoxins and the incidence of molds identified in the study suggests that stricter control is needed to safeguard the health of the substantial population consuming maize as a staple diet.

Apigeninidin-rich Sorghum bicolor (L. Moench) extracts suppress A549 cells proliferation and ameliorate toxicity of aflatoxin B1-mediated liver and kidney derangement in rats. Sci Rep 2022; 12:7438. [PMID: 35523904 PMCID: PMC9076626 DOI: 10.1038/s41598-022-10926-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Accepted: 04/08/2022] [Indexed: 02/07/2023] Open
Abstract
Sorghum bicolor plant has a high abundance of 3-deoxyanthocyanins, flavonoids and other polyphenol compounds that have been shown to offer numerous health benefits. Epidemiological studies have linked increased intake of S. bicolor to reduced risk of certain cancer types, including lung adenocarcinoma. S. bicolor extracts have shown beneficial effects in managing hepatorenal injuries. This study investigated the cytotoxic potential of three apigeninidin-rich extracts of S. bicolor (SBE-05, SBE-06 and SBE-07) against selected cancer cell lines and their ameliorative effect on aflatoxin B1 (AFB1)-mediated hepatorenal derangements in rats. We observed that, among the three potent extracts, SBE-06 more potently and selectively suppressed the growth of lung adenocarcinoma cell line (A549) (IC50 = 6.5 μg/mL). SBE-06 suppressed the expression of STAT3 but increased the expression of caspase 3. In addition, SBE-05, SBE-06 and SBE-07 inhibited oxidative and nitrosative stress, inflammation, and apoptosis and preserved the histoarchitectural networks of the liver and kidney of rats treated with AFB1. These in vitro and in vivo studies indicate the potential of these cheap and readily accessible extracts for cancer therapy and as chemo-preventive agents in preventing aflatoxin-related health issues.

Abstract
Pregnant women are vulnerable to certain environmental agents, one of which is aflatoxin. As one of the most popular aflatoxins, Aflatoxin B1 (AFB1) has recently garnered increased attention concerning its potential association between exposure and adverse pregnancy outcomes. The aims of the study were to examine the associations between prenatal exposure to AFB1 and postpartum hemorrhage (PPH), and whether coagulation function has a mediating effect on their relationship. A total of 379 mother-infant pairs were included in the present study. Prenatal serum AFB1 albumin (AFB1-Alb) adduct levels in peripheral venous blood were detected by using an ELISA kit. Multiple linear and logistics regression models were applied to analyze the relationship between AFB1-Alb levels and PPH. We found mothers with high levels of AFB1-Alb adduct levels had significantly increased postpartum blood loss (partial regression coefficient (β) = 50.71, 95% confidence interval (CI) 3.48, 97.95). Mothers with high levels of AFB1-Alb adduct levels also had significantly increased risk of PPH (odds ratio (OR) = 4.81, 95% CI 1.01, 22.98). Moreover, concentrations of AFB1-Alb were positively associated with activated partial thromboplastin time (APTT) while negatively associated with fibrinogen (FIB). One-unit increase in APTT was correlated with a 6.62-ml (95% CI 3.04, 10.20) increase in postpartum blood loss. Mediation analysis suggested that the maternal blood APTT levels had a positive mediating effect in the association between AFB1-Alb adduct levels and postpartum blood loss (β = 0.32, 95% CI 0.04, 0.68). These results indicated that prenatal exposure to AFB1 was associated with increased postpartum blood loss, possibly by interfering with maternal APTT levels.

ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2022; 92:103847. [PMID: 35283284 DOI: 10.1016/j.etap.2022.103847] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 03/06/2022] [Accepted: 03/09/2022] [Indexed: 06/14/2023]
Abstract
The purpose of this study was to assess the risk of aflatoxins due to multiple food consumption among the Zhejiang population. Ultra-high-performance liquid chromatography coupled with tandem mass spectrometry method was used to determine aflatoxins in 792 samples. Aflatoxins were detected in 27.1% of the samples at levels between 0.07 and 262.63 μg kg-1, and aflatoxins B1 was the most frequently detected among different types of samples. 0.8% of peanut oil, 3.39% of nut products as well as 1.1% of condiments contaminated with aflatoxins B1 exceeded China national tolerance limits. Peanut oil had the highest incidence of aflatoxin, with a range from 0.17 to 22.50 μg kg-1. Using bags conferred limited advantages in reducing aflatoxin contents. Moreover, peanut and rice were the main contributors to dietary exposure to aflatoxins among Zhejiang residents. Finally, the margin of exposure values obtained by rice consumption were far from the safe margin of 10,000, indicating a potential risk to public health. The results pointed out the need for further prioritization of aflatoxins B1 risk-management actions in Zhejiang.

Burden of Disease Associated with Dietary Exposure to Aflatoxins in China in 2020. Nutrients 2022; 14:nu14051027. [PMID: 35268003 PMCID: PMC8912679 DOI: 10.3390/nu14051027] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 02/21/2022] [Accepted: 02/22/2022] [Indexed: 01/03/2023] Open
Abstract
Aflatoxins (AFTs), as a group 1 carcinogen, could lead to hepatocellular carcinoma (HCC). Dietary intake is the primary way of AFT exposure in humans. However, the contribution of foodborne AFT intake to the HCC burden remains unknown in recent years in China. Hence, the present study was conducted to estimate the burden of HCC attributed to foodborne AFT exposure by using disability-adjusted life years (DALYs). The risk assessment was used to estimate the incidence of HCC related to AFT exposure. Concentrations of AFTs in peanuts, peanut oil, corn, and corn products were retrieved from literature published between 2010 and 2020 in China. Corresponding daily food consumption data were obtained from two nationwide Chinese surveys. A direct approach was used to calculate DALY and DALY rates to quantify the HCC burden attributed to dietary AFT exposure. The total amount of AFT intake through peanut, peanut oil, corn, and corn products was 4.018 ng/kg bw/day resulting in 0.125 extra HCC cases per year/100,000 persons, corresponding to a DALY number and DALY rate of 21,625.08 and 1.53 per 100,000 population, respectively. Regionally, DALYs were high in Guangxi and Guangdong provinces, corresponding to 5948 and 5595 DALYs. A total of 1.5 DALYs/100,000 were lost due to the AFT exposure. DALYs per 100,000 population were higher in several coastal areas. Though the disease burden of HCC caused by dietary AFTs was low in the Chinese population, a high health risk was found in the residents of some areas with high AFT exposure. AFTs are still a health challenge for the Chinese people.

Abstract
Aflatoxicosis can induce largescale toxicities in predisposed populations. Food fortification with adequate antioxidant sources may reduce the toxic burden from aflatoxicosis. We examined the individual and combined effect of Caffeic acid (CA) on the aflatoxin B1 (AFB1)-induced hepatic and renal injury in male rats. Five experimental rat cohort (n = 6) consisting of the control (2 mL/kg corn oil), AFB1 alone (50 μg/kg), CA alone (40 mg/kg), AFB1+CA1 (50 μg/kg + 20 mg/kg) and AFB1+CA2 (50 μg/kg + 40 mg/kg) were so treated for 28 consecutive days. Upon sacrifices, diagnostic markers of hepatorenal functions, oxidative stress, inflammation, oxidative deoxyribonucleic acid -DNA-damage and apoptosis were analysed. Our results showed that CA reduced AFB1-induced toxicities in rats' liver and kidneys by significantly increasing (p < 0.05) endogenous antioxidant and the anti-inflammatory IL-10 level. Caffeic acid simultaneously reduced hepatic and renal dysfunction biomarkers in the serum, oxidative stress, and lipid peroxidation levels. Besides, CA diminished reactive oxygen and nitrogen species, inflammatory nitric oxide levels, interleukin-1 β and the activities of xanthine oxidase and myeloperoxidase. Additionally, CA reduced DNA damage and caspase-mediated apoptotic responses and preserved the cytoarchitecture of rats' liver and kidneys treated with AFB1. These data suggest that CA can be used as a food additive to mitigate AFB1-induced toxicity in the examined organs.

Abstract
The present study was undertaken to explore the inhibitory effect of Levisticum officinale Koch. essential oil (LoffEO) on the growth and aflatoxin B1 secretion by Aspergillus flavus (AF-LHP-SH1, aflatoxigenic strain) causing deterioration of stored chia seeds (Salvia hispanica). The chemical profile analysis of LoffEO by GC-MS analysis revealed the presence of α-terpinyl acetate (26.03 %) as a major component followed by terpineol <1- > (24.03 %) and citronellal (24.03 %). Results on antifungal and antiaflatoxigenic activity indicated that LoffEO at 2.0 and 1.75 μL/mL caused complete inhibition of growth and aflatoxin B1 production, respectively. Antifungal toxicity of LoffEO was strongly correlated with the inhibition of ergosterol content, leakage of cellular ions, and disintegration of membrane permeability. Reduction in cellular methylglyoxal by LoffEO indicated a novel antiaflatoxigenic mechanism of action. The LoffEO showed moderate free radical quenching activity in DPPH assay (IC50 = 26.10 μL/mL) and exhibited remarkable inhibitory efficacy against lipid peroxidation of chia seeds. In addition, LoffEO presented strong in situ antiaflatoxigenic efficacy, and exhibited non-phytotoxic nature, acceptable sensory characteristics, and favorable safety profile (LD50 = 19786.59 μL/kg), which recommends its practical utilization as a novel and safe preservative to improve the shelf life of stored chia seeds from fungal infestation and aflatoxin B1 contamination.

Occurrence and Health Risk Assessment of Aflatoxins through Intake of Eastern Herbal Medicines Collected from Four Districts of Southern Punjab-Pakistan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:9531. [PMID: 34574455 PMCID: PMC8466447 DOI: 10.3390/ijerph18189531] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Revised: 09/05/2021] [Accepted: 09/06/2021] [Indexed: 12/22/2022]
Abstract
Eastern herbal medicines (HMs) are plant-derived naturally occurring substances with minimum or no industrial processing that have long been used in traditional medicine. Aflatoxins are frequent contaminants of plants. Therefore, these mycotoxins are likely to contaminate HMs and pose a health risk to individuals using them on a regular basis as preventive or curative treatments of various diseases. The present study aimed to determine aflatoxin levels in the most popular Pakistani HM formulations and to assess the health risk associated with the intake of aflatoxins. A total of 400 samples of HM formulations collected from four districts of Punjab were analyzed for the quantification of aflatoxins, out of which 52.5% were found to be contaminated. The average daily dose (ADD) of AFB1 and AFs through the intake of HM formulations ranged between 0.00483 and 0.118 ng/kg bw/day and between 0.00579 and 1.714 ng/kg bw/day, respectively. The margin of exposure (MOE) and population cancer risk ranged from 99.49 to 29378.8 and from 0.00011 to 0.0325 liver cancer cases/105 individuals/year (0.0075-2.455 liver cancer cases/105 individuals/75 years), respectively. Despite the low exposure to aflatoxins from HM formulations in the four studied Punjab (Pakistan) districts, the frequent contamination of the analyzed samples suggests that official measures should be considered to manage the associated risk.

Abstract
Aflatoxins (AFs) are one of the most harmful carcinogenic natural toxins that affect food. Crops containing reasonably high oil content may be affected by Aspergillus species and consequently by AF contamination. In this study, a proposed testing method for AF detection in oilseed was developed, validated, and used for a market survey to assess the probabilistic risk exposure caused by consuming contaminated oilseeds including corn, sunflower seed, and soybean. The test method was optimized for selective extraction and then validated for fitness of purpose; the limits of quantification (LOQs) were 0.2, 0.4, 0.2, and 0.2 μg kg-1 for aflatoxin G1 (AFG1), aflatoxin B1 (AFB1), aflatoxin G2 (AFG2), and aflatoxin B2 (AFB2), respectively. The method was linear from the LOQs up to 20 μg kg-1, and its budget of measurement uncertainties were estimated at 25, 24, 26, and 30 for AFG1, AFB1, AFG2, and AFB2, respectively. The contamination levels were from <LOQ to 2.65 μg kg-1 and from <LOQ to 26.9 μg kg-1 for corn and sunflower oilseed samples, respectively, whereas the soybean samples were AF-free. According to the consumption rate of corn and sunflower seeds, the estimated margins of exposure to AFB1 were 721 and > 10,000 body weight (BW) day-1, respectively. The main finding of the present study highlights the possibility of some risk of AF exposure from corn consumption, which may represent a health concern.

Predicted Aflatoxin B 1 Increase in Europe Due to Climate Change: Actions and Reactions at Global Level. Toxins (Basel) 2021; 13:toxins13040292. [PMID: 33924246 PMCID: PMC8074758 DOI: 10.3390/toxins13040292] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 04/16/2021] [Accepted: 04/18/2021] [Indexed: 02/07/2023] Open
Abstract
Climate change (CC) is predicted to increase the risk of aflatoxin (AF) contamination in maize, as highlighted by a project supported by EFSA in 2009. We performed a comprehensive literature search using the Scopus search engine to extract peer-reviewed studies citing this study. A total of 224 papers were identified after step I filtering (187 + 37), while step II filtering identified 25 of these papers for quantitative analysis. The unselected papers (199) were categorized as “actions” because they provided a sounding board for the expected impact of CC on AFB1 contamination, without adding new data on the topic. The remaining papers were considered as “reactions” of the scientific community because they went a step further in their data and ideas. Interesting statements taken from the “reactions” could be summarized with the following keywords: Chain and multi-actor approach, intersectoral and multidisciplinary, resilience, human and animal health, and global vision. In addition, fields meriting increased research efforts were summarized as the improvement of predictive modeling; extension to different crops and geographic areas; and the impact of CC on fungi and mycotoxin co-occurrence, both in crops and their value chains, up to consumers.

Toxins (Basel) 2020; 12:toxins12120777. [PMID: 33291337 PMCID: PMC7762301 DOI: 10.3390/toxins12120777] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Accepted: 12/02/2020] [Indexed: 11/16/2022] Open
Abstract
Microbial degradation is an effective and attractive method for eliminating aflatoxin B1 (AFB1), which is severely toxic to humans and animals. In this study, Aspergillus niger RAF106 could effectively degrade AFB1 when cultivated in Sabouraud dextrose broth (SDB) with contents of AFB1 ranging from 0.1 to 4 μg/mL. Treatment with yeast extract as a nitrogen source stimulated the degradation, but treatment with NaNO3 and NaNO2 as nitrogen sources and lactose and sucrose as carbon sources suppressed the degradation. Moreover, A. niger RAF106 still degraded AFB1 at initial pH values that ranged from 4 to 10 and at cultivation temperatures that ranged from 25 to 45 °C. In addition, intracellular enzymes or proteins with excellent thermotolerance were verified as being able to degrade AFB1 into metabolites with low or no mutagenicity. Furthermore, genomic sequence analysis indicated that the fungus was considered to be safe owing to the absence of virulence genes and the gene clusters for the synthesis of mycotoxins. These results indicate that A. niger RAF106 and its intracellular enzymes or proteins have a promising potential to be applied commercially in the processing and industry of food and feed to detoxify AFB1.

Spatial analysis of dietary exposure of aflatoxins in peanuts and peanut oil in different areas of China. Food Res Int 2020; 140:109899. [PMID: 33648201 DOI: 10.1016/j.foodres.2020.109899] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 11/03/2020] [Accepted: 11/05/2020] [Indexed: 12/29/2022]
Abstract
Peanuts in China are heavily contaminated with aflatoxin, which pose a threaten to human health. To compare the dietary exposure risk of aflatoxins (AFT) in peanuts and peanut oil in different areas of China, the spatial distribution of AFT contamination levels in peanuts and peanut oil from different areas was analyzed. The dietary exposure was calculated by simple distributed risk assessment method before characterizing the health risk using both the margin of exposure (MOE) approach proposed by the European Food Safety Authority (EFSA) and the quantitative liver cancer risk approach proposed by the Joint Food and Agricultural Organization/World Health Organization (FAO/WHO) Expert Committee on Food Additives (JECFA). The results showed that the AFT content in peanuts and peanut oil was high with agglomeration in several provinces of East and South China under a subtropical temperate monsoon climate, and the AFT contamination in peanut oil was more substantial than peanuts. On average, the estimated dietary exposure to AFT from the total of peanuts and peanut oil for Chinese general population ranged from 1.776 to 1.940 ng/kg bw/day (LB-UB), from which the MOE values of 88-96 (UB-LB) and liver cancer risk of 0.055-0.060 cases/100,000 persons/year (LB-UB) were calculated. As for different areas in China, the mean AFT exposure ranged between 0.000 and 17.270 ng/kg bw/day. Moreover, the corresponding health risk was estimated at 10-868759 MOE values and 0.000-0.851 liver cancer cases/100,000 persons/year. Guangdong, Fujian and Jiangxi provinces were at a higher risk rank. The liver cancer risk of AFT exposure from peanuts and peanut oil was far below all-cause liver cancer incidence (18.0 cases/100,000 persons/year) in China, but several areas with relatively high risk should be of concern. Compared with other age groups, children aged 2-6 years should be paid more attention because they have the highest AFT exposure level.

Nuts and Non-Alcoholic Fatty Liver Disease: Are Nuts Safe for Patients with Fatty Liver Disease? Nutrients 2020; 12:nu12113363. [PMID: 33139607 PMCID: PMC7693493 DOI: 10.3390/nu12113363] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Revised: 10/23/2020] [Accepted: 10/25/2020] [Indexed: 12/16/2022] Open
Abstract
Diet and lifestyle interventions are the recommended treatment for patients with non-alcoholic fatty liver disease (NAFLD), with the aim of achieving a 7-10% weight loss. Several dietary patterns have been suggested for this purpose, however, to date, the best one is represented by the Mediterranean diet (MD) as it is rich in macro- and micro- nutrients known for their effectiveness in health-promotion and cardio-vascular disease prevention. Moreover, MD is characterized by the inclusion of nuts. These foods have shown potential benefits in health-promotion as they are rich in fibers, which have lipid-lowering effects, rich in mono- and poly-unsaturated fatty acids, which help reduce insulin-resistance and serum cholesterol, and contain anti-oxidants which reduce oxidative stress and inflammation. Additionally, nuts are associated with a better control, or reduction, of Body Mass Index (BMI). All these effects are useful targets to achieve in NAFLD, so that nuts have been proposed as a suitable dietary treatment supplement for weight and metabolic control in these patients. In recent years, health authorities raised an alert on nuts consumption as these may be at high risk of aflatoxin (AF) contamination, for which controls and legislations are different among countries. AF is a well-known cancerogenic agent and a recognized risk factor for hepatocellular carcinoma. Patients with NAFLD have an overall, inherent sevenfold increased risk of developing hepatocellular carcinoma as compared with the general population. In this context, one could argue that recommending the inclusion of nuts in the diet of NAFLD patients has to be balanced with the risk of potential chronic exposure to AF, and every effort should be pursued to assure the safety of these nutrients. In this review, we aim to summarize the benefits of nuts consumption, the evidence for AF contamination of nuts and the consequent potential risks in patients with NAFLD.

Abstract
Aflatoxin B1 (AFB1) contamination in foods is an important health challenge for low-and middle-income countries in subtropical regions. AFB1 has been detected in a variety of foodsin Guangzhou, while the risk of dietary exposure is unknown. This study aimed to assess the probabilistic risk of dietary exposure to AFB1 contamination in food stuffs in Guangzhou by using margin of exposure (MOE) and quantitative liver cancer risk approaches. A total of1854 AFB1-contaminated foodstuffs were sampled in supermarkets, agricultural markets, retail shops, and family workshops from 11 districts of Guangzhou, and AFB1 content was determined by HPLC-fluorescence detector. In total, 9.9% (184/1854) of the test samples had AFB1 concentrations above the limit of detection. Home-made peanut oil had the highest AFB1 concentration, with a mean value of 38.74 ± 47.45 μg kg-1. The average MOE levels of Guangzhou residents ranged from 100 to 1000. The risk of liver cancer was 0.0264 cancers (100,000 population year)-1. The health risks of suburban people were higher than those of urban people, and home-made peanut oil was the main contributorto dietary exposure to AFB1 among suburban residents in Guangzhou. The production of home-made peanut oil should be supervised to reduce the risk of AFB1 exposure.

Abstract
This study investigated the health risks associated with aflatoxins (AFs) in processed meat products (PMP) sold in Riyadh, Kingdom of Saudi Arabia. The occurrence and levels of AFs were assessed using high-performance liquid chromatography with fluorescence detection (HPLC-FD), whereas the cancer risk attributed to the consumption of meat products containing AFs was estimated by means of margin of exposure (MOE) on a scale of 100-600, representing high and low exposure, respectively. The results indicated that 37.5% of the samples were contaminated, with concentrations ranging from 0.30 to 52.93 μg/kg, at an average of 6.4 ± 12.58 μg/kg. The percentage contamination levels with total AFs higher than the permissible Saudi limit of 20 μg/kg were 4% of samples analysed and 10% of contaminated samples. AFB1 and AFG1 were the most prevalent toxins, followed by AFB2; AFG2 was not detected in any sample. The MOE was found to be 175 and 311 for total AFs in processed beef meat and poultry meat products, respectively. These results showed that the daily intake of AF-contaminated PMP may constitute a public health concern. To our knowledge, this is the first study to report the health risk associated with PMP contaminated with AFs.

Abstract
Aflatoxin B1 (AFB1) induces hepatocellular carcinoma (HCC) through consumption of contaminated food in Southern China. Aldo-keto reductase-7A (AKR7A) functionally plays a potent role in the biodetoxification in the liver. In addition, hepatocellular lipid disorder has found to be closely linked to the development of HCC. This study was, therefore, designed to investigate the potent bioeffect of AKR7A on the lipid metabolism in AFB1-exposed hepatocellular carcinoma cells through assaying human cancerous samples and cell culture. In the baseline data, the HCC patients showed increased contents of AFB1 in sera and cancerous samples. In the clinical parameters, the HCC patients demonstrated changed lipid settings in sera. As revealed by immunostaining and immunoblotting, AFB1-elevated HCC sections showed marked down-regulation of AKR7A expression, accompanied with reduced ApoB expression and increased CD36, S6K1 expressions in the HCC. Studies in the human hepatocarcinoma line HepG2 also showed AFB1-exposure to increase ApoA1, LDL, TC, and TG contents; induce cell proliferation; and reduce hepatocellular AKR7A expression. Furthermore, AKR7A bioactivity was inactivated after treatment with perfluorooctane sulfonate (PFOS), an ApoB activator, in AFB1-dosed HepG2 cells. Collectively, our current findings suggest that hepatocellular AKR7A has a protective role against AFB1-induced cytotoxicity through the regulation of CD36, S6K1 and ApoB expression through the reduction of lipid utilization in malignant liver cells.

Abstract
The tropical, warm, and humid conditions that are favorable to the growth and development of mycotoxigenic fungi put the Philippines at a high risk of mycotoxin contamination. To date, seven mycotoxigenic Aspergillus species, four Fusarium species, and one Penicillium species have been isolated from various agricultural crop commodities in the country. There are five mycotoxin groups (aflatoxin, fumonisin, ochratoxin, nivalenol, and zearalenone) that have been detected in both the raw form and the by-products of major crops grown in the country. Since the first scientific report of aflatoxin contamination in the Philippines in 1972, new information has been generated on mycotoxins and mycotoxigenic fungi, but little has been known of other mycotoxins until the last two decades. Further, despite the increase in the understanding of mycotoxigenic fungi and mycotoxins in the country, very limited knowledge exists on practices and measures that control both the fungi and the toxins. This paper reviews the current literature on mycotoxigenic fungi and mycotoxins in the Philippines with emphasis on the last two decades and on other mycotoxins.

Abstract
The main objective of this research was to perform an exposure assessment of aflatoxins intake through consumption of maize products in Serbia, Croatia, and Greece. Food consumption survey of maize-based products has been performed during 2017 in the three countries with at least 1,000 interviewees per country covering their dietary habits and body weight. Values for the concentration of aflatoxins were extracted from available research published in the last ten years. Finally, a Monte Carlo analysis of 100,000 iterations was performed to estimate the intake of aflatoxins from consumption of maize-based products. Results revealed that the estimated average exposure of adults to aflatoxins, from maize consumption, in each of the three countries was between 0.44 ng kg-1 bw day-1 and 5.59 ng kg-1 bw day-1. Margin of exposure values for the mean exposure levels, in all three countries, were between 30 and 389. Estimations for hepatocellular carcinoma cases/year/105 individuals, depending on the HBsAg+ prevalence, were 0.075-0.098, 0.006-0.008 and 0.020-0.026 for Serbia, Croatia and Greece, respectively.

Toxins (Basel) 2018; 10:E436. [PMID: 30373285 PMCID: PMC6265880 DOI: 10.3390/toxins10110436] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Revised: 10/26/2018] [Accepted: 10/26/2018] [Indexed: 12/20/2022] Open
Abstract
Hepatoblastoma incidence has been associated with different environmental factors even if no data are reported about a correlation between aflatoxin exposure and hepatoblastoma initiation. Considering that hepatoblastoma develops in infants and children and aflatoxin M1 (AFM1), the aflatoxin B1 (AFB1) hydroxylated metabolite, can be present in mothers' milk and in marketed milk products, in this study we decided to test the effects of AFM1 on a hepatoblastoma cell line (HepG2). Firstly, we evaluated the effects of AFM1 on the cell viability, apoptosis, cell cycle, and metabolomic and cytokinomic profile of HepG2 cells after treatment. AFM1 induced: (1) a decrease of HepG2 cell viability, reaching IC50 at 9 µM; (2) the blocking of the cell cycle in the G0/G1 phase; (3) the decrease of formiate levels and incremented level of some amino acids and metabolites in HepG2 cells after treatment; and (4) the increase of the concentration of three pro-inflammatory cytokines, IL-6, IL-8, and TNF-α, and the decrease of the anti-inflammatory interleukin, IL-4. Our results show that AFM1 inhibited the growth of HepG2 cells, inducing both a modulation of the lipidic, glycolytic, and amino acid metabolism and an increase of the inflammatory status of these cells.

Abstract
Aflatoxins are fungal metabolites found in feeds and foods. When the ruminants eat feedstuffs containing Aflatoxin B1 (AFB1), this toxin is metabolized and Aflatoxin M1 (AFM1) is excreted in milk. International Agency for Research on Cancer (IARC) classified AFB1 and AFM1 as human carcinogens belonging to Group 1 and Group 2B, respectively, with the formation of DNA adducts. In the last years, some epidemiological studies were conducted on cancer patients aimed to evaluate the effects of AFB1 and AFM1 exposure on cancer cells in order to verify the correlation between toxin exposure and cancer cell proliferation and invasion. In this review, we summarize the activation pathways of AFB1 and AFM1 and the data already reported in literature about their correlation with cancer development and progression. Moreover, considering that few data are still reported about what genes/proteins/miRNAs can be used as damage markers due to AFB1 and AFM1 exposure, we performed a bioinformatic analysis based on interaction network and miRNA predictions to identify a panel of genes/proteins/miRNAs that can be used as targets in further studies for evaluating the effects of the damages induced by AFB1 and AFM1 and their capacity to induce cancer initiation.
