A recent study sought to better understand the ability of Listeria monocytogenes biofilms on stainless steel surfaces to withstand common industry sanitizers, chlorine and PAA, using strains and temperature conditions relevant to the fresh leafy greens supply chain.
An ongoing Center for Produce Safety-funded study is investigating the factors contributing to the persistence of a reoccurring, emerging, and persisting (REP) Escherichia coli O157:H7 subtype associated with leafy greens foodborne illness outbreaks, with the goal of developing a risk assessment tool for growers.
A new Southern California-based study found that food safety may play a role in UTIs. Genomic analysis of Escherichia coli isolates from UTI patients and retail meats linked 18 percent of UTIs to E. coli strains of animal origin, suggesting foodborne transmission.
ECDC has provided an update on a multi-year, multi-national outbreak of Salmonella Strathcona linked to tomatoes from Sicily, Italy, which has grown to 437 confirmed cases in 17 European countries, plus the UK, the U.S., and Canada.
Although this severe Escherichia coli strain is already prevalent in countries with less robust food safety and sanitation systems, as climate change becomes more extreme and cuts are made to food safety monitoring and infrastructures, it is becoming a growing threat to developed countries as well, researchers warn.
The Cornell College of Agriculture and Life Sciences (CALS) Food Safety Laboratory has developed the Salmonella Serovar Wiki—a web resource for global food safety professionals to rapidly access information about a given Salmonella serovar.
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.
A 2024 European foodborne illness outbreak caused by a rare Salmonella serotype, linked to leafy greens grown near a buffalo farm, exposed gaps in biosecurity, surveillance, and data transparency across the agri-food system.
A new study assessed the efficacy of a commercial lytic bacteriophage cocktail as a preharvest agricultural water treatment against Salmonella Infantis, and found modest but consistent pathogen reductions across diverse water conditions.
New research has demonstrated a low overall prevalence of Campylobacter on retail chicken meat; however, recovered C. jejuni strains did not match known poultry-associated genotypes, suggesting the need for sensitive detection methods and expanded genomic surveillance.
