This episode of Food Safety Five covers a novel detection method for Clostridium botulinum and a potential new processing approach to mitigate contamination, as well as growing discussion around how C. botulinum should be handled in infant formula manufacturing, spurred by recent botulism outbreaks.

This episode of Food Safety Five discusses new research linking sorbitol to fatty liver disease, studies suggesting potential health risks associated with both “natural” and artificial color additives, and a major collection of papers examining the health impacts, policy, and marketing practices behind ultra-processed foods (UPFs).

This episode of Food Safety Five discusses new research on the use of cold plasma technologies for biofilm inactivation and reducing allergenic risk, deriving more accurate “sell by” dates based on microbial changes on meat, and ultra-processed food nutrition and purchasing realities.

This episode of Food Safety Five discusses several foodborne pathogens that have been recently highlighted by researchers due to their unusual nature, emergence, and increasing public health significance, including a rare Salmonella strain, an STEC/ETEC hybrid, Group B Streptococcus, and drug-resistant Shigella.

This episode of Food Safety Five discusses new academic publications exploring the limitations of a “zero-risk” approach to food safety and evaluating the limited benefits and trade-offs associated with intensified microbiological sampling.

This episode of Food Safety Five discusses the Environmental Working Group’s 2026 “Dirty Dozen” list of the most “pesticide-contaminated produce,” including ongoing debate over the list’s methodology and its relevance to food safety and public health.

This episode covers new research on food allergen risks in processing environments, including studies on allergen recovery from environmental swabs, cross-contamination in shared frying oil, and dispersal of allergenic food powders. Also discussed is an EU proposal to harmonize precautionary allergen labeling (PAL) requirements.

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.

This episode of Food Safety Five discusses updated USDA-FSIS guidance on Listeria testing in RTE facilities, the latest on the Boar’s Head facility behind the fatal outbreak of 2024, and a real-world Listeria “Seek and Destroy” success story.

This episode of Food Safety Five discusses new research about the rising Salmonella disease burden worldwide and the utility of whole genome sequencing (WGS) for Salmonella surveillance.
