Food Safety Publications

The Food Safety Publications tracks research that is published across national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. The research publications are tracked across six categories: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, Produce Safety, and Viruses. Articles produced by USDA Grant Funding Agencies and FDA Grant Funding Agencies are also tracked.

  1. Dual transcriptome based reconstruction of Salmonella-human integrated metabolic network to screen potential drug targets

    • Wed, 05/25/2022 - 06:00
    • PLOS ONE
    • by Kadir Kocabaş, Alina Arif, Reaz Uddin, Tunahan Çakır Salmonella enterica serovar Typhimurium (S. Typhimurium) is a highly adaptive pathogenic bacteria with a serious public health concern due to its increasing resistance to antibiotics. Therefore, identification of novel drug targets for S. Typhimurium is crucial. Here, we first created a pathogen-host integrated genome-scale metabolic network by combining the metabolic models of human and S.

    • Food Control
    • Rapid detection of antibiotic resistance genes (ARGs) of food microorganisms is critical for preventing the spread of ARGs via the food chain. In this study, slipchip-based immunomagnetic separation (IMS) combined with loop-mediated isothermal amplification (LAMP) was developed for rapid, specific, sensitive and multi-sample detection of Bacillus cereus with tetracycline resistance gene tetL in pasteurized milk. First, the magnetic nanoparticles coated with anti-B.

  5. Behaviour and adhesion capacity of Listeria monocytogenes on Mozzarella di Bufala Campana PDO cheese and in fluids involved in the production process

    • Wed, 05/25/2022 - 06:00
    • Food Control
    • Listeria monocytogenes is a foodborne pathogen for humans. It can be found in ready-to-eat (RTE) products and its presence represents one of the biggest food safety concerns. Most of the cases of cheese contamination reported by the Rapid Alert System for Food and Feed (RASFF) in the last 10 years did not involve Mozzarella di Bufala Campana (MBC) Protected Designation of Origin (PDO) cheese.

    • International Journal of Dairy Technology
    • International Journal of Dairy Technology, EarlyView. The aim of the present study was to assess Aflatoxin-M1 (AFM1) contamination in cheese samples from the West Asia region. Furthermore, AFM1 contamination was investigated based on the texture type (hard, semi-soft/semi-hard and soft) and the maturation process (matured and fresh) of the cheese sampled. Our results indicated that AFM1 contamination occurs in more than 50% of the cheese samples from all included countries.

    • Peritrophins are peritrophic membrane (PM) proteins that can interact with chitin fibers via chitin-binding domains. Peritrophins have essential roles in providing porosity and strength to the PM that lines the shrimp midgut. Acute hepatopancreatic necrosis disease (AHPND), caused by strains of V. parahaemolyticus, is known to initially colonize the shrimp stomach and simultaneously disrupt its structural barriers (e.g., cuticle or epithelial tissues) to reach the hepatopancreas.
