- Abstract:
- ... Authentication of food and feed covers a broad range of topics, matrices, analytical techniques and research approaches. To address future challenges of authenticity testing, cooperation among public institutes becomes more and more important. In this perspective, the Federal Institute for Risk Assessment (BfR) organized a German-wide meeting (translated title: Status quo of authenticity testing o ...

- Abstract:
- ... Aflatoxin M₁ is one of the most common toxic natural substances found worldwide. It metabolizes from aflatoxin B₁ that is present in the diet of mammals. In this study, 84 milk samples were investigated in total, and 63 (75 %) were contaminated with aflatoxin M₁ above the limit of detection. No difference was observed between the samples from organic and conventional systems (0.021 vs. 0.018 µg/kg ...

- Abstract:
- ... We investigated the changes of free 3-monochloropropane-1,2-diol content in two groups of shortcrust pastry samples (salty crackers and sweet biscuits) stored under different conditions. The experiment involved an impact assessment of 2 packaging types (paper and polyethylene), different storage time (from 1 to 5 months) and sunlight exposure. Our results show a significant decrease in compound le ...

- Abstract:
- ... We investigated the composition of muscle tissue from 30 untreated striped catfish (Pangasianodon hypophthalmus) and 40 untreated pikeperch (Sander lucioperca). The analyzed fillets had a mean moisture level of 77.5 % in striped catfish and 78.7 % in pikeperch. The mean level of protein content was 19 % in striped catfish and 20.5 % in pikeperch; the pH was 6.5 in striped catfish and 6.8 in pikepe ...

- Abstract:
- ... Delivery of foreign DNA is still a very controversial issue, especially in relation to genetically modified organisms. It is not necessary to use genetically modified feed to verify the possible transfer of DNA from food into the body. In this study, we evaluated the possible transfer of DNA from wheat forage (of single component diet) into the blood of three different organisms. DNA isolation kit ...

- Abstract:
- ... Aflatoxin M1 (AFM1) is a metabolite of aflatoxin B1 (AFB1) and secreted in milk of animals that are kept on a moldy diet. AFB1 is produced by several toxigenic species of fungi. In this study, the comparative efficacy of two mycotoxin binders was evaluated in terms of reducing excretion of AFM1, total viable bacterial count and somatic cell count in milk obtained from goats fed with AFB1 contamina ...

- Abstract:

Within 2 months, two water sources in a karst area in Switzerland were sampled 9 times each, and analyzed by real-time PCR for 6 EHEC O-types, Shiga-like-toxin (stx1 and stx2) and intimin (eae) genes. With the exception of O111, 5 O-types were recorded regularly and at high frequencies (O26: 33.3 %; O157: 33.3 %; O104: 66.6 %; O103: 72.2 %; O145: 94.4 %). Genes for Shiga-like-toxins and intimin we ...

Therefore, it is necessary to raise awareness of food defence at every level of the food chain, from farm to fork, from government and academic institutions to retail chains, the media and consumers. The principles of food defence can be implemented at every level of the foo ...

A fermentation with Lactobacillus plantarum ATCC 8014 was carried out for comparison. Fermentation was performed at room temperature during 120 days in two different concentrations of NaCl (2.4–13.6 % w/v) and sucrose (0–0.82 % w/v) in the brines. The pH, ch ...

- Abstract:
- ... Often, food-borne outbreaks cannot be clarified. One reason for this is that foods are no more available for testing once the outbreak is detected. Specifically, this can be the case for foods with a short shelf-life, such as plant foods. Moreover, sometimes the food matrix leads to performance failures of laboratory methods. In such situations, investigational tracing can be the key to outbreak c ...

Forty eight samples were collected from four local herbal shops in Manisa, Turkey. Of the 48 samples analyzed, 43 were aflatoxin positive. The highest concentration of aflatoxin (34.18 µg/kg) was determined in a sample of ca ...
