Abstract Introduction The transfer of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) from a contaminated environment into the food chain is a serious consumer safety problem. As part of the Polish National Surveillance Program of PCDD/Fs and PCBs in food of animal origin, a concentration of PCDD/Fs of 4.61 ± 0.75 pg WHO-TEQ/g fat was determined in a sample of free-range eggs, which exceeded the permitted limit of 2.5 pg WHO-TEQ/g. The aim of the study was to investigate the source of the egg contamination and the risk for the eggs’ consumers. Materials and methods Eggs, muscles, feed and soil from the place where backyard waste burning had been carried out in the past and ash from a household stove tipped onto the paddock were analysed using the isotope dilution technique with high-resolution gas chromatography coupled with high-resolution mass spectrometry. Results The concentration in ash was low at 0.20 pg WHO-TEQ/g and the congener profile did not indicate the source of contamination. The dioxin content in soil from the backyard waste-burning site was 2.53 pg WHO-TEQ/g dry matter (d.m.) and the soil’s profile of PCDD/F congeners matched the profile of the contaminated eggs. Conclusion By reason of the congener profile similarity, the investigation concluded, that the cause of the contamination was the backyard waste-burning site soil which the animals had access to. Frequent consumption of contaminated eggs from the analysed farm could pose a health risk due to chronic exposure, especially for vulnerable consumers.

(Poly)phosphates are approved as water-preserving and emulsifying agents that improve the appearance and consistency of many food products. The labelling of added (poly)phosphates is essential for protecting vulnerable population groups and to prevent unfair trade practices resulting in economic fraud. The problems with (poly)phosphates’ utilisation concerns both analytical and legislative issues, such as: (1) their straightforward detection; (2) excessive addition altering freshness perception and misleading consumers; (3) uncontrolled usage increasing foodstuff weight; (4) application in products where they are not permitted; and (5) no indication on the label. Bearing all these issues in mind, the main purpose of this study was the quantification and screening of the (poly)phosphates profile in meat, marine and dairy products (160 samples), of which 43 were without declared (poly)phosphate treatment. Analysis was completed by high-performance ion-exchange chromatography either with conductometric detection or coupled to Q-Exactive Orbitrap high-resolution mass spectrometry. Although the (poly)phosphates profiles varied greatly according to species and processing type, the following criteria for detection of illicit treatment were established: high orthophosphate level, quantified short-chain (poly)phosphate anions and the presence of long-chain forms. In conclusion, the instrumental platforms used in this study can be recommended to inspection bodies as reliable methods for the detection of food adulteration with (poly)phosphates.

Monitoring the presence of residues of unauthorized substances, chemical and biological residues, medicinal products and radioactive contamination in food is an important element of the system for protection of consumers against hazardous foods. The aim of the study was to analyze the results of monitoring tests for the presence of antibiotics and chemotherapeutics affecting consumer safety in products of animal origin that were carried out in Poland in the years 2003-2017. The material for analysis were annual reports on the results of tests for the presence of prohibited substances, chemical and biological residues, medicinal products and radioactive contamination in food produced in Poland. Samples for testing were taken at random from food of animal origin produced on farms under the supervision of the Veterinary Inspectorate. The reports present data on monitoring tests carried out in the years 2003-2017. The analysis was based on the results for B1 substances, which include antibacterial substances, antibiotics and chemotherapeutics approved for use in food-producing animals. The results from the last two years of research were analyzed in detail, including the results for prohibited substances with antibacterial action from group A6 (prohibited substances) and, in the case of poultry, for coccidiostats (group B2b).The results of the monitoring studies in Poland indicate that both veterinarians and animal breeders were aware that the proper use of chemotherapeutics and compliance with waiting periods are necessary to ensure food safety. Samples that exceeded the standards represented less than 0.3% of all samples tested in all types of food. According to the results of these studies, antibiotic residues were most frequently found in honey.

Occurrence of antimicrobial residues in livestock and aquatic products is a current public health concern. The monitoring of food commodities for antimicrobial residues will ensure the consumer safety and promote trade. Therefore, the objective of this study was to establish a screening test to detect antimicrobial residues in food of animal origin. A bioassay consists of six plates was established, which enables screening of six groups of antimicrobials, namely; penicillins, sulphonamides, streptomycin, erythromycin, tetracyclines and fluroquinolones. The Six Plate Test (SPT) is a bioassay technique, which is carried out using Bacillus subtilis BGA (Merck), Bacillus cereus (ATCC 11778), Micrococcus luteus (ATCC 9341) and Escherichia coli (ATCC 11303) as indicator organisms. The Mueller Hinton Agar (MHA) was used as the test medium at optimum pH for all indicator organisms except B.cereus, for which the Media No.8 was used. The Minimum Detectable Concentrations (MDC) of SPT were determined using serial dilutions of antibiotics. All the MDC values obtained on SPT for the validated antimicrobials were below the recommended MRL of each antimicrobial. SPT can be developed to a quick, easy to perform, robust and low cost screening test to detect antimicrobial residues in food of animal origin.

AbstractIntroductionThis paper reports polychlorinated dibenzo-p-dioxin (PCDD), polychlorinated dibenzofuran (PCDF), and polychlorinated biphenyl (PCB) concentrations in fish collected from Polish and Vietnamese farms and the related risk for consumers.Material and MethodsAltogether, 160 samples were analysed using an isotope dilution technique with high-resolution gas chromatography coupled with high-resolution mass spectrometry (HRGC-HRMS). To characterise the potential health risk associated with PCDD/F and dioxin-like polychlorinated biphenyl (DL-PCB) intake, doses ingested in two 100 g portions of fish by adults and children were calculated and expressed as the percentage of the tolerable weekly intake (TWI) newly established by the EFSA in November 2018 at 2 pg WHO-TEQ kg−1 b.w.ResultsGenerally, levels in fish muscles were low in relation to maximum limits (4), being in the range of 0.02–3.98 pg WHO-TEQ g−1 wet weight (w.w.) for PCDD/F/DL-PCBs and 0.05–24.94 ng g−1 w.w. for NDL-PCBs. The highest concentration was found in eel muscles. The least polluted were pangas and zanders and the levels were at the limits of quantification. Consumption of two portions of fish per week results in intakes of 9– 866% TWI by children and 4–286% TWI by adults.ConclusionFrequent consumption of some species (for example eel and bream) can pose a health risk to vulnerable consumers and especially children and pregnant women.

Health Significance

Background and Aim: Food of animal origin such as milk is vital for nutritional security and should be free of any antibiotic residues due to its public health significance. We designed a study aiming to determine the occurrence of antibiotic residues and in further levels of oxytetracycline residues in pooled raw milk samples from Palakkad district, Kerala. Materials and Methods: We collected pooled raw milk samples were collected from Alathur, Chittoor, and Palakkad blocks of Palakkad district, Kerala. A total of 215 samples were screened for antibiotic residues by microbial inhibition assay (MIA) and the positive samples were subjected to enzyme-linked immunosorbent assay (ELISA) to determine oxytetracycline residues, this was further confirmed using high-performance liquid chromatography (HPLC). Results: We found that out of the 215 pooled raw milk samples screened for antibiotic residues using MIA, 22 samples (10.23%) were positive for antibiotic residues from Palakkad, Kerala. Out of these 22 samples, five (2.33%) were positive for oxytetracycline residues. We further calculated the mean concentration of oxytetracycline residues in these five samples and estimated it to be 201.00±41.25 ng/mL and 272.11±53.21 ng/mL using ELISA and HPLC, respectively. On analyzing these five samples, we found that four samples (1.86%) exceeded the maximum residue limits level of 100 ng/mL for oxytetracycline residues in milk as specified by Codex Alimentarius Commission/Food Safety and Standards Authority of India (FSSAI). Conclusion: This study revealed that the occurrence of oxytetracycline residues in pooled raw milk samples in the Palakkad district of Kerala. Hence, there is a need for surveillance and monitoring of antibiotic residues in milk due to its impact on public health to ensure consumer safety.
