Originally limited to Great Value products sold at Walmart, FDA is warning consumers not to eat or purchase imported frozen shrimp sold under five additional brand names, originating from a single distributor, due to potential radioactivity. 

A study from the University of Florida College of Veterinary Medicine suggests that commensal Escherichia coli strains could be utilized to mitigate antibiotic-resistant nontyphoidal Salmonella Heidelberg, ultimately improving food safety.

FDA has issued a safety alert raw frozen shrimp products that tested positive for radioactive isotope Celsium-137, which were imported from Indonesia and sold at Walmart stores in 13 states. The agency recommends a recall.

This article discusses the use of big data and philosophical challenges with food safety for commercial products.

FDA has updated its list of chemicals currently under post-market review, which now includes six additional artificial food colorants, among other chemicals. The agency is also expediting the review of chemicals included in previous updates, like phthalates and titanium dioxide.

Commissioned by the UK Food Standards Agency (FSA), a survey of prepacked salmon filets sold at supermarkets in the UK showed a low presence of Listeria monocytogenes and Escherichia coli, as well as low levels of antimicrobial resistance (AMR). 

The 2025 Center for Produce Safety (CPS) Symposium offered practical solutions for growers, packers, and food safety professionals, based on findings from new research and emerging technologies aimed at strengthening produce safety across the supply chain.

A new study led by the University of Georgia’s Center for Food Safety has confirmed that imported seafood carries colistin resistance genes that are capable of transfer, posing the risk of this resistance gene spreading via the U.S. food supply. 

This episode of Food Safety Five discusses two scientific developments that could help address the risk posed by Cronobacter in powdered infant formula: an AI-powered analysis of genetic data for C. sakazakii, providing new insight into why it persists in low-moisture foods, and the development of a promising new assay.

In this bonus episode of Food Safety Matters, we speak to Elanco Poultry Account Manager Vic Fox about the components and importance of a holistic integrated Salmonella control program in modern poultry operations, and how Elanco supports poultry producers with a multidisciplinary approach.
