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.

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous in food, cosmetics, and pharmaceuticals. Part 2 of this article series discusses the application of several problem-solving analytical tools to the PFAS crisis, as well as the impacts of PFAS on the United Nations' Sustainable Development Goals (SDGs) for 2030.

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.

In November 2025, FDA will host a three-day, virtual public meeting on food allergen thresholds and their potential applications. Input received during the public meeting will help FDA determine next steps, establish priorities, and develop food allergen threshold approaches.
