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.

In his remarks on a recent Joe Rogan Experience podcast episode, Secretary Kennedy also suggested FDA is considering a new approach to front-of-pack nutrition labeling.

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.

Of the 111 “Generally Recognized as Safe” (GRAS) additives identified by the Environmental Working Group (EWG), 49 are known to be widely used by food manufacturers.

However, concerning levels of arsenic and lead were detected in some products, and Consumer Reports is therefore urging FDA to set limits for these metals in infant formula. PFAS were also found in more than a quarter of products.

This episode of Food Safety Five discusses expert perspectives on the Healthy Florida First food contaminant testing program, including information gaps about the testing and risk assessment methodology and why this missing information matters.

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.
