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.

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.

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.

A recent study found that Listeria monocytogenes from multispecies biofilms exhibits higher growth in ready-to-eat (RTE) cold-smoked salmon than L. monocytogenes from single-species biofilms. Additionally, L. monocytogenes contamination from the multi-species biofilm surpassed EU regulatory limits after 15 days of storage.

A new study led by the University of South Australia offers a promising real-time mycotoxin detection method for the food industry that is based in artificial intelligence (AI) technology, and overcomes some of the limitations of traditional detection methods.

In France, 21 people have been sickened and two have died in a listeriosis outbreak linked to pasteurized milk cheeses produced by the Chavegrand company. Additionally, one person in Belgium has been infected with the same strain of Listeria monocytogenes.

Boar’s Head is planning to reopen a production plant that was linked to a deadly, multistate listeriosis outbreak in 2024. Meanwhile, inspection reports obtained by the Associated Press show that insanitary conditions similar to those that caused the outbreak continue to plague other Boar’s Head facilities.

This article examines control of Listeria contamination of meat and poultry products by smaller-scale meat/poultry producers.
