Food Safety Five Newsreel

RSS

This episode of Food Safety Five reads between the lines of the revised Dietary Guidelines for Americans, discussing its use of the term “highly processed foods,” how its definition differs (or does not differ) from the debated “ultra-processed foods” category, and the potential implications for food policy.

This episode of Food Safety Five discusses a food safety issue that was covered in some of our most-read scientific articles of 2025: microplastics release from food contact materials and contamination of food.

This episode of Food Safety Five discusses scientific recommendations around ultra-processed food (UPF) definitions and policy, a study demonstrating the antimicrobial efficacy of common sanitizers in potato wash water, and a review outlining the food safety risks of edible flowers. Also discussed are regulatory and standards developments in the U.S., EU, and at the international level.

This episode of Food Safety Five discusses a farm-to-fork quantitative microbial risk assessment (QMRA) for Listeria monocytogenes in cantaloupe, a study demonstrating the efficacy of antimicrobial peptides for reducing Salmonella in poultry, and the adoption of new international standards at the 48^th session of the Codex Alimentarius Commission.

This episode of Food Safety Five discusses research on Listeria biofilms, including sanitizer efficacy and evolutionary insights, and on a persisting Escherichia coli strain in leafy greens. It also covers regulatory developments in the UK, Canada, and the UAE, as well as a potential U.S. ultra-processed foods (UPFs) definition.

This episode of Food Safety Five discusses hoses as reservoirs for biofilms in food processing facilities, the presence of Listeria monocytogenes and Campylobacter on retail beef and chicken, a new Salmonella serovar database, and microplastics release from food contact materials.

This episode of Food Safety Five discusses a UK proposed ban on Bisphenol A (BPA) in food contact materials, as well as two studies with global relevance: a successful clinical trial for a novel Salmonella vaccine and research demonstrating how nanoplastics enter the edible parts of crops.

This episode of Food Safety Five discusses allergen news in the EU, where experts recommend “hidden” food allergens for mandatory labeling, and in the U.S., where USDA-FSIS is adding gluten to its allergen verification activities.

This episode of Food Safety Five discusses recent events at CDC, from the loss of officials to program cuts, and how these changes are impacting food safety work.

This episode of Food Safety Five discusses three recent studies that examine the risk of Listeria monocytogenes growth from multi-species biofilm contamination, how imported seafood may spread antibiotic resistance genes, and a promising AI mycotoxin detection method.
