Food Safety Five Ep. 20: The Latest Research on Listeria Biofilms, E. coli, and the UPFs Debate
This episode of Food Safety Five discusses a study that evaluated the antimicrobial efficacy of chlorine and peracetic acid (PAA) against Listeria monocytogenes biofilms, a first-of-its kind application of experimental evolution to understand the genetic and phenotypic adaptations that enable L. monocytogenes to form robust biofilms, and an ongoing project investigating a reoccurring, emerging, and persisting (REP) Escherichia coli strain that has been linked to multiple leafy greens-associated foodborne illness outbreaks. Additionally, we mention the U.S. debate over a potential, federally recognized definition for “ultra processed foods” (UPFs), and several other regulatory updates from the UK, Canada, and the United Arab Emirates (UAE).
