Almášiová S, Toman R, Pšenková M, Tančin V, Jančo I. Toxic Elements in Sheep Milk, Whey, and Cheese from the Environmentally Burdened Area in Eastern Slovakia and Health Risk Assessment with Different Scenarios of Their Consumption. TOXICS 2024; 12:467. [PMID: 39058119 PMCID: PMC11280966 DOI: 10.3390/toxics12070467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2024] [Revised: 06/21/2024] [Accepted: 06/24/2024] [Indexed: 07/28/2024]
Abstract
The study aimed to determine the content of 17 elements (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sb, Se, Sr, and Zn) in samples of sheep milk, cheese, and whey (36 samples in total) collected from a farm in an environmentally burdened area due to the long-term mining and industrial activity in Slovakia as well as to determine the possible risk of consumption via health risk assessment calculations. Consumption of 120 g of milk, 500 g of milk, 20 g of cheese, and 100 g of cheese were used in calculations for children and adults, respectively. According to the results, concentrations of four elements are controversial. Lead concentrations in all types of samples exceeded the maximum permissible lead limit in milk set by European Union legislation. The content of Se and As is problematic for children's consumption, and the target hazard quotient for As and Al is higher than one (considered potentially not safe) in all scenarios. According to the target system approach, lead concentrations in milk and cheese could adversely influence the nervous system and kidneys of adults' and children's developmental and reproductive systems. Considering the worst-case scenario, consuming sheep milk and cheese from the monitored areas could represent a risk and be potentially harmful to human health, mainly for children. However, further monitoring of the levels of elements and concentrations in environmentally burdened areas and more robust data on consumption are needed.

Food Chem 2024; 436:137713. [PMID: 37857194 DOI: 10.1016/j.foodchem.2023.137713] [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: 06/29/2023] [Revised: 09/11/2023] [Accepted: 10/08/2023] [Indexed: 10/21/2023]
Abstract
Mineral elements (Ca, Na, K, Mg, Zn, Ti, Sr, Fe, Ni, Ba, Cr, Mn, Cu, Se, Cd, Mo, B, V, As, Pb and Hg) in Provola cheeses obtained from dairy cows fed with two different integrated diets (Biotrak) and without olive cake (Control) were determined to discriminate between the two different cheeses. The results showed that cheeses from the Biotrak group presented higher values of essential elements. Selenium (Se) was found to be the most interesting: in Biotrak cheeses the content of Se was in the range of 0.112 to 0.281 mg/kg, about twice the content of Se in cheeses from the Control group. Among the toxic elements, only Cd was found in the samples, but at low levels (in average lower than 0.11 mg/kg). Therefore, the use of olive cake in animal feed is a good strategy to improve the mineral profile of the product obtained.

Abstract
OBJECTIVE Although milk and dairy products are almost complete food, they can contain toxic heavy elements with potential hazards for consumers. This review aims to provide a comprehensive report on the occurrence, concentration, and health risks of selected heavy metals in pasteurized and sterilized milk recorded worldwide. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was used to develop this systematic review. Databases included the Web of Knowledge, Scopus, Scientific Information Database, Google Scholar, and PubMed from inception until January 2023. Keywords related to the terms "Heavy metals", "Arsenic" and "Pasteurized and sterilized milk" and "Risk Assessment" were used. The potential health risks to human health from milk daily consumption were estimated using extracted data on heavy metals concentration based on metal estimated daily intake, target hazard quotient, and carcinogenic risk. RESULTS A total of 48 potentially relevant articles with data on 981 milk samples were included in the systematic review. Atomic Absorption Spectroscopy, atomic absorption spectroscopy, inductively coupled plasma-mass spectrometry, and inductively coupled plasma-optical emission spectrometry were the most common valid methods to measure heavy metals in milk samples. Following the initial evaluation, Cu, Cd, Zn, and Pb were the most contaminants, which exceeded the maximum permissible criteria in 94%, 67%, 62%, and 46% of the milk samples tested. Relying on target hazard quotient and carcinogenic risk results, milk consumers in 33(68.75%) and 7 (14.5%) studies were exposed to moderate to high levels of carcinogenic and non-carcinogenic risk, respectively. The highest level of risk is due to the consumption of pasteurized and sterilized milk detected in Pakistan, Brazil, Egypt, Slovakia, and Turkey. CONCLUSION The elevated levels of heavy metals in milk samples, especially Pb and Cd is a public health concern; therefore, maximum control and strict regulations must be adopted to decrease heavy metals contaminants in the dairy industry. Further studies are required to develop safe milk processing and handling methods for the decontamination of heavy metals in milk and its products.

Abstract
The aim of this study was to investigate the effects of exposure of cattle to low levels of environmental pollution on trace metal metabolism. The assessment of heavy metal concentrations in blood samples is essential to evaluate the potential effects of pollutants on cattle production and to measure the uptake of pollutants by animals. For this purpose, cattle raised in villages at varying distances to the center of the Kars province were sampled for blood, and heavy metal concentrations were measured in the extracted sera. In total 150 blood samples were collected from 4-to 5-year-old cattle from 15 regions. Sera were extracted from the blood samples from the selected foci and analyzed with an inductively coupled plasma-optical emission spectrometry (ICP-OES) device for essential (Co, Cr, Cu, Fe, Mn, Ni and Zn, Se, V) and non-essential (Pb, Cd and Hg, As, Al, Sn) heavy metals. Heavy metals were detected in the serum samples in the following order: Sn > Fe > Al > Zn > Cu > Pb > Cr > As > V > Ni > Mn > Hg. A confidence interval of 95% was used to evaluate all tests. Differences between the villages were insignificant for the Cu, Pb, Cd, Hg, Se, Al, Co concentrations (p > 0.05), whereas differences between the villages were significant for the Fe, As, Ni, Mn (p < 0.05), Zn, Cr (p < 0.01), V and Sn (p < 0.001) concentrations. The results of this study show that heavy metals detected in bovine sera from the sampling area do not exceed the maximum permissible limits, suggesting limited exposure to heavy metals and no associated health risk to animals in the region.

Abstract
The aim of this work was to determine the concentrations of selected mutagenic elements (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Se) in raw ewe milk from undisturbed environment in Orava region, northern Slovakia. There are possible sources of some of the analyzed metals which may be distributed from the metallurgical plants located in the Ostrava region, Czech Republic, and Katowice, Poland. In total, forty milk samples were analyzed in June and August using an inductively coupled plasma optical emission spectrometry. The differences in elements concentrations between the seasonal periods were not significant except of iron (p < 0.0001). The concentrations of most of the metals in ewe milk were low and under the permissible or recommended limits. However, arsenic and selenium concentrations were elevated and could pose a risk of the mutagenic effect, particularly in children. The frequency of element occurrence in June was as follows: Se > Fe > As > Cu > Mn > Ni > Co > Pb > Cr > Cd, and in August: Se > Fe = As > Cu > Mn > Pb > Co > Ni > Cr > Cd. The correlation analysis revealed very strong positive correlation between Cu:Pb (p < 0.05), very strong negative correlation between Fe:Se (p < 0.05). The strong correlations were also found between other elements. The present study showed that milk produced in the relatively undisturbed environment might contain various mutagenic elements. The relationships between the elements might result in the additive or synergistic effects of elements and increase the risk of their mutagenic effects even in low concentrations. Therefore, attention must be paid to the monitoring of metals in the areas where food sources destined especially for child nutrition are produced.

Abstract
Concentrations of selected trace elements Ag, Co and V in raw milk sampled from four geographical regions in Croatia were measured. Silver, Co and V were detected above the limit of detection within the range of 9.52%-30.8%, 1.6%-12.1% and 12.4%-30.8%. Silver concentrations were not detected in milk samples from the Croatian Littoral and Mountainous Croatia (CL-MC) region. Similar Ag content was found in Southern, Eastern and Central Croatia. The lowest mean of Co and V of 33.2 and 83.8 µg kg-1 were found in the CL-MC region while the highest of 49.8 and 136.9 µg kg-1 was found in Central Croatia. There were no statistically significant differences in Ag, Co and V contents between the four regions. The estimated daily dietary intakes (EDI) of total mean and total 95th percentile values of Ag, Co and V showed lower values in comparison with available EFSA health-based limits.

Abstract
Cow's milk is currently the most consumed product worldwide. However, due to various direct and indirect contamination sources, different chemical and microbiological contaminants have been found in cow's milk. This review details the main contaminants found in cow's milk, referring to the sources of contamination and their impact on human health. A comparative approach highlights the poor efficacy and effects of the pasteurization process with other methods used in the treatment of cow's milk. Despite pasteurization and related techniques being the most widely applied to date, they have not demonstrated efficacy in eliminating contaminants. New technologies have appeared as alternative treatments to pasteurization. However, in addition to causing physicochemical changes in the raw material, their efficacy is not total in eliminating chemical contaminants, suggesting the need for new research to find a solution that contributes to improving food safety.

Abstract
The objective of this study was to measure the concentrations of eleven essential, potentially toxic and toxic elements (arsenic – As, calcium – Ca, cadmium – Cd, copper – Cu, iron – Fe, mercury – Hg, magnesium – Mg, nickel – Ni, lead – Pb, selenium – Se, zinc- Zn) in raw cow’s milk (spring, summer, and autumn season), feed (spring and autumn season) and soil (spring season) from three different environments by routine methods in the certified testing laboratory. The samples were collected in the undisturbed region around Novoť, the moderately disturbed region around Tulčík, and the strongly disturbed region around Čečejovce. The concentrations of all toxic elements (As, Cd, Hg, Ni, Pb) and two essential elements (Cu, Se) in milk were under the limits of quantification (LOQ) from all investigated areas and during all seasons. Concentrations of other elements in milk from the undisturbed and disturbed areas were significantly different, generally with the highest levels in summer. In soil samples, the significantly highest concentrations of Ca, Cu, Ni were found in a strongly disturbed area, Mg and As in moderately disturbed area, and Fe, Se, Zn, Hg, and Pb in an undisturbed area. Cadmium was under the LOQ. In feed, the concentrations of essential elements, except of Se, were higher in the autumn. The significantly highest concentration of As, Ni were recorded in a moderately disturbed area and Pb in the undisturbed area in both seasons. Cadmium and Hg were under the LOQ. Despite the higher level of some elements in soil (Fe, Mg, Ca) from all regions, there were not elevated concentrations of any element in feed or milk. The concentrations of all toxic elements in milk were under the permitted limits. Thus, the milk from all investigated areas was not contaminated with the elements posing a health risk for consumers and it is considered safe for human consumption.
