The California Longitudinal Study, a five-year environmental study of California’s Central Coast produce-growing region, identified wildlife, livestock, and surface water as potential contributors to the persistence and movement of Shiga toxin-producing Escherichia coli (STEC).
Maximum reductions in norovirus infectivity occurred rapidly once temperatures reached 60 °C (140 °F). The findings could help inform improved thermal processing recommendations for foodborne norovirus.
The researchers positioned the machine learning model as a low-cost complement to traditional testing workflows, helping dairy processors enhance food safety while targeting laboratory resources.
Incorporating a novel “bio-fumigation” method based on a natural compound produced by mustard plants, the micro-malting machine effectively addresses mycotoxins while preserving quality. USDA is working with industry to scale the prototype for widespread adoption.
Researchers found that the presence of nanoplastic particles can increase the expression of virulence and antimicrobial resistance (AMR) genes in Salmonella,and can also encourage biofilm formation.
In an analysis of domestic refrigerator swabs, researchers discovered complex microbial communities harboring foodborne pathogens and antimicrobial resistance (AMR). The findings also suggested that regular cleaning is possibly more important than temperature control in managing these communities.
Unlike plastic, the mycelium- and cellulose-based material is biodegradable and free of chemicals of concern. It is likely safe for humans and the environment in the long term, as demonstrated by humanity’s history of consuming fungi.
Dispersibility may be a useful tool for simulating the spread and hygienic control of allergenic food powders. Researchers recommend that producers add powders from as low a position as possible to reduce the risk of cross-contamination.
The researchers conducted environmental sampling throughout a controlled environment agriculture (CEA) operation and tested swabs for L. monocytogenes. Boot covers proved to be a useful tool for evaluating the effectiveness of cleaning and sanitation.
A new study quantified the allergen cross-contamination that occurs in shared frying oil and evaluated the efficacy of different filters in removing allergen protein residues from oil.
