Food Addit Contam Part A Chem Anal Control Expo Risk Assess 2023:1-11. [PMID: 37267476 DOI: 10.1080/19440049.2023.2218941] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 05/17/2023] [Accepted: 05/19/2023] [Indexed: 06/04/2023]
Abstract
This study examined the production of eight key biogenic amines (methylamine, tryptamine, putrescine, cadaverine, histamine, tyramine, spermidine, and spermine) in 120 samples of farmed rainbow trout during various storage conditions, and determined any accompanying variations in pH. The main objective of this study was to identify which of the eight biogenic amines could be used as chemical markers to evaluate the quality of farmed rainbow trout. Histamine and tryptamine were not present in any of the samples, and the levels of cadaverine were inconsistent. The levels of putrescine significantly increased at 0 °C (by day 9), 2 °C (by day 8), and 4 °C (by day 4). Tyramine, spermidine, and spermine levels exhibited fluctuations but had a significant positive correlation with the levels of putrescine. The pH levels slightly increased from their initial values across all storage temperatures, with no significant variations observed. Based on the results, it can be concluded that putrescine may serve as an effective marker of the freshness of farmed rainbow trout during storage.

Abstract
Objectives We analysed 900 samples of fresh (250) and processed (650) fish products collected in Sicily (Southern Italy) in 2020 during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic (hereafter: COVID-19). Materials and methods The samples were divided temporally based on five phases relating to the various restrictions imposed by the Italian government in this period. The validated method of ultra-high performance liquid chromatography (UHPLC) combined with a diode array detector (DAD) was then employed for the analysis. Results The samples collected during the Phase I lockdown period and after it had ended (Phase II) revealed significant increases in the mean histamine levels: 41.89±87.58 mg/kg -1 and 24.91±76.76 mg/kg -1, respectively. The 11 (1.3% of the total) fresh fish samples that were identified as being non-compliant with EC Reg. 2073/2005 were only found during these two periods. All the processed samples were always compliant. The histamine values decreased as the restrictions eased, achieving a mean value of 11.16±9.3 mgkg -1 (Phase III). Conclusions There was an increase in the incidence of fish samples that were non-compliant with EC Reg. 2073/2005 compared to previous surveillance data. These results provide a first report on the effect of lockdown measures on food safety and the cold chain. Our findings must cause food safety operators to intensify their controls over fresh fish products in such periods to safeguard consumer health. Further studies are required to evaluate whether the same trend would be observed with other food contaminants.

Geographic Pattern of Sushi Product Misdescription in Italy-A Crosstalk between Citizen Science and DNA Barcoding. Foods 2021; 10:foods10040756. [PMID: 33918119 PMCID: PMC8066630 DOI: 10.3390/foods10040756] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 03/22/2021] [Accepted: 03/27/2021] [Indexed: 01/19/2023] Open
Abstract
The food safety of sushi and the health of consumers are currently of high concern for food safety agencies across the world due to the globally widespread consumption of these products. The microbiological and toxicological risks derived from the consumption of raw fish and seafood have been highlighted worldwide, while the practice of species substitution in sushi products has attracted the interest of researchers more than food safety agencies. In this study, samples of sushi were processed for species authentication using the Cytochrome Oxidase I (COI) gene as a DNA barcode. The approach of Citizen Science was used to obtain the sushi samples by involving people from eighteen different Italian cities (Northern, Central and Southern Italy). The results indicate that a considerable rate of species substitution exists with a percentage of misdescription ranging from 31.8% in Northern Italy to 40% in Central Italy. The species most affected by replacement was Thunnus thynnus followed by the flying fish roe substituted by eggs of Mallotus villosus. These results indicate that a standardization of fish market names should be realized at the international level and that the indication of the scientific names of species should be mandatory for all products of the seafood supply chain.

Abstract
Superchilling entails lowering the fish temperature to between the initial freezing point of the fish and about 1-2°C lower. The temperature of superchilled fresh fishery products (SFFP) in boxes without ice was compared to that of products subject to the currently authorised practice in boxes with ice (CFFP) under the same conditions of on-land storage and/or transport. A heat transfer model was developed and made available as a tool to identify under which initial configurations of SFFP the fish temperature, at any time of storage/transport, is lower or equal to CFFP. A minimum degree of superchilling, corresponding to an ice fraction in the fish matrix of SFFP equal or higher than the proportion of ice added per mass of fish in CFFP, will ensure with 99-100% certainty (almost certain) that the fish temperature of SFFP and the consequent increase of relevant hazards will be lower or equal to that of CFFP. In practice, the degree of superchilling can be estimated using the fish temperature after superchilling and its initial freezing point, which are subject to uncertainties. The tool can be used as part of 'safety-by-design' approach, with the reliability of its outcome being dependent on the accuracy of the input data. An evaluation of methods capable of detecting whether a previously frozen fish is commercially presented as 'superchilled' was carried out based on, amongst others, their applicability for different fish species, ability to differentiate fresh fish from fish frozen at different temperatures, use as a stand-alone method, ease of use and classification performance. The methods that were considered 'fit for purpose' are Hydroxyacyl-coenzyme A dehydrogenase (HADH) test, α-glucosidase test, histology, ultraviolet-visible-near-infrared (UV-VIS/NIR) spectroscopy and hyperspectral imaging. These methods would benefit from standardisation, including the establishment of threshold values or classification algorithms to provide a practical routine test.

Abstract
On-land transport/storage of fresh fishery products (FFP) for up to 3 days in 'tubs' of three-layered poly-ethylene filled with freshwater and ice was compared to the currently authorised practice (fish boxes of high-density poly-ethylene filled with ice). The impact on the survival and growth of biological hazards in fish and the histamine production in fish species associated with a high amount of histidine was assessed. In different modelling scenarios, the FFP are stored on-board in freshwater or seawater/ice (in tubs) and once on-land they are 'handled' (i.e. sorted or gutted and/or filleted) and transferred to either tubs or boxes. The temperature of the FFP was assumed to be the most influential factor affecting relevant hazards. Under reasonably foreseeable 'abusive' scenarios and using a conservative modelling approach, the growth of the relevant hazards (i.e. Listeria monocytogenes, Aeromonas spp. and non-proteolytic Clostridium botulinum), is expected to be < 0.2 log10 units higher in tubs than in boxes after 3 days when the initial temperature of the fish is 0°C ('keeping' process). Starting at 7°C ('cooling-keeping' process), the expected difference in the growth potential is higher (< 1 log10 for A. hydrophila and < 0.5 log10 for the other two hazards) due to the poorer cooling capacity of water and ice (tub) compared with ice (box). The survival of relevant hazards is not or is negligibly impacted. Histamine formation due to growth of Morganella psychrotolerans under the 'keeping' or 'cooling-keeping' process can be up to 0.4 ppm and 1.5 ppm higher, respectively, in tubs as compared to boxes after 3 days, without reaching the legal limit of 100 ppm. The water uptake associated with the storage of the FFP in tubs (which may be up to 6%) does not make a relevant contribution to the differences in microbial growth potential compared to boxes.

Abstract
La amina biógena más importante en pescado es la histamina, ya que es el peligro más frecuentemente implicado en los brotes relacionados con estos alimentos. Causa una intoxicación de tipo alérgico asociada con el consumo de pescado, sobre todo de escómbridos como el atún y la caballa. La histamina resulta de la descarboxilación del aminoácido histidina por la enzima histidina descarboxilasa, que se produce por un grupo de bacterias. La mayoría de éstas son mesófilas, sin embargo, investigaciones recientes indican que algunas bacterias producen cantidades significativas de histamina a temperaturas de 0º a 50 ºC. Además, la enzima histidina descarboxilasa, generada durante el almacenamiento del pescado a altas temperaturas, continúa activa a temperaturas inferiores y es responsable de la producción de histamina a 50 ºC o por debajo. Los modelos matemáticos predictivos aplicados en este estudio, muestran cómo la formación de histamina en pescados frescos ricos en histidina, es marcadamente más rápida cuando éstos se conservan a temperaturas de refrigeración más elevadas.

Abstract
Histamine poisoning is the most common cause of human foodborne illness due to the consumption of fish products. An enzyme-based amperometric biosensor was developed to be used as a screening tool to detect histamine and histamine-producing bacteria (HPB) in tuna. It was developed by immobilizing histidine decarboxylase and horseradish peroxidase on the surface of screen-printed electrodes through a cross-linking procedure employing glutaraldehyde and bovine serum albumin. The signal generated in presence of histamine at the surface of the electrode was measured by chronoamperometry at in presence of a soluble redox mediator. The sensitivity of the electrode was 1.31-1.59 μA/mM, with a linear range from 2 to 20 μg/ml and detection limit of 0.11 μg/ml. In this study fresh tuna filets purchased in supermarkets in different days (n = 8) were analyzed to detect HPB. Samples with different concentration of histamine were analyzed with culture-based counting methods, biosensor and HPLC and also a challenge test was made. Recovery of histamine from cultures and tuna samples was also assessed. The presence of Morganella psychrotolerans, Photobacterium phosphoreum, P. damselae and Hafnia alvei was detected using culture- and PCR-based methods. At the time of purchase these tuna samples had histamine concentrations from below the limit of detection (LOD) to 60 μg/g. HPLC and biosensor methods provided similar results in the range from zero to 432 μg/g (correlation coefficient, R 2 = 0.990) and the recovery of histamine from cultures and tuna samples was very high (mean bias -12.69 to 1.63%, with root-mean-square error <12%). These results clearly show that fresh tuna is commonly contaminated with strong HPB. The histamine biosensor can be used by the Food Business Operators as a screening tool to detect their presence and to determine whether their process controls are adequate or not.

Abstract
The consumption of food containing high amounts of histamine and other biogenic amines can cause food poisoning with different symptoms linked to the individual sensitivity and the detoxification activity. Histamine is the only biogenic amine with regulatory limits set by the European Commission in fish and fishery products, because it can lead to a fatal outcome. However, also fermented foods can be involved in outbreaks and sporadic cases of intoxication. The factors affecting the presence of histamine in food are variable and product specific including the availability of the precursor amino acid, the presence of microorganisms producing decarboxylases, and the conditions allowing their growth and enzyme production. Generally, the good quality of raw material and hygienic practices during food processing as well as the use of histidine decarboxylase-negative starter cultures can minimize the occurrence of histamine. Further studies are necessary to estimate the human exposure and the relationship between the total amount of the biogenic amines ingested with food and health effects.
