This episode of Food Safety Five discusses two recent scientific studies that are advancing the food industry’s understanding of and ability to address Listeria monocytogenes, including new findings about the pathogen’s behavior in biofilms and a developing rapid detection method.
A Boston University study has shown that Escherichia coli exposed to microplastics form strong biofilms and develop increased levels of antimicrobial resistance (AMR) and multi-drug resistance.
A new study by USDA researchers has shown that long-read whole genome sequencing (WGS) could detect Salmonella attachment to food-contact surfaces earlier than traditional culture-based methods, allowing for sanitation interventions to be applied before the maturation of robust and difficult-to-remove biofilms.
According to a pre-publication version of a study conducted by Cornell University and backed by FDA, aging raw milk cheese may not be effective at eliminating the Highly Pathogenic Avian Influenza H5N1 virus. However, adequate heat treating or pH 5.0 conditions could be effective.
Scientists have discovered antibodies that can neutralize a wide range of norovirus strains, laying the groundwork for a broadly effective vaccine. Historically, development of a norovirus vaccine has been hindered by the virus’ many genetic variants and frequent mutation.
A joint study by World of Auditing and Çağ University aims to deliver science-based insights into the size, scope, and dynamics of food safety auditing challenges and opportunities. Please share your insights in the survey!
A recent study has revealed that nearly 100 million people in the U.S. are exposed to unregulated chemicals in their drinking water—including solvents, refrigerants, and PFAS—with Hispanic populations most disproportionately affected.
A recent study demonstrated the ability of Listeria monocytogenes to colonize a preexisting multispecies biofilm within a matter of hours and survive within the biofilm over time, without significantly altering the community structure or the overall matrix composition.
A survey of Swedish toddlers conducted by the Swedish Food Agency as part of the Riksmaten Young Children dietary study has found high levels of some toxic substances—such as PFAS, BPA, and lead—in the children’s bodies.
A research project funded by the Center for Produce Safety is developing a flexible computer model that enables food industry users to evaluate potential contamination risks along the supply chain and relevant control strategies.
