Based on data from the Salinas Valley, California growing region, the model could complement existing produce safety assessments by helping regulators, researchers, and industry stakeholders identify locations that may warrant additional environmental investigation.
The agency is particularly interested in input from commercial vendors on serogroup-independent solutions and methods compatible with meat-based microbiology testing.
FDA, CDC, and USDA-FSIS researchers analyzed foodborne illness surveillance data against targets set under the Healthy People initiative, finding worsening incidence of campylobacteriosis, listeriosis, and STEC infections, with no detectable change in salmonellosis incidence, while acknowledging the potential role of advanced surveillance methods.
Supported by the Center for Produce Safety (CPS), Cornell researchers are developing a quantitative microbial risk assessment (QMRA) model to evaluate how quality defects affect Listeria and E. coli growth on produce, helping identify effective interventions and improve processes.
Food Standards Scotland (FSS) has outlined its plans to reduce foodborne illness over the next three years, prioritizing Campylobacter, Listeria monocytogenes, and Shiga toxin-producing Escherichia coli, as well as its related research objectives.
Outbreak strains include STEC serotypes O26:H11, O103:H25, and O168:H8 and one strain of Salmonella Agona. Some people were infected with more than one outbreak strain. The implicated products were distributed by Everything Sprouts LLC of Minneapolis, Minnesota.
This episode of Food Safety Five discusses new research on avocado oil authenticity in processed foods, the effects of nanoplastics on bacterial biofilms in drinking water systems, factors influencing Listeria monocytogenes persistence on plastic food contact surfaces, and stress-adaptation traits that may help E. coli persist from farm to fork.
UKHSA said the relatively stable number of STEC notifications in 2025 marked a departure from the steady annual increases observed since 2021, when larger outbreaks contributed substantially to case counts.
Adding to a growing body of evidence that micro- and nanoplastics may enhance the virulence and persistence of pathogens in food and the environment, a new study found that nanoplastics may strengthen E. coli biofilms in drinking water systems and increase resistance to chlorine treatment.
The co-occurrence of biofilm formation, acid tolerance, and antimicrobial resistance genes in E. coli isolatedfrom irrigation water, soil, and crops could complicate downstream microbial control efforts in produce production systems.
