With the hope of developing a user-friendly model, a Center for Produce Safety-funded study is investigating factors that influence Escherichia coli contamination risks posed by concentrated animal feeding operations (CAFO) near produce growing fields.
In a retrospective analysis of two Listeria monocytogenes outbreaks linked to packaged salads, CDC epidemiologists underline key learnings and suggest proactive measures for industry.
The new COMPASS optical sorter from Key Technology combines high-performance foreign material contamination detection and removal with gentle, hygienic product handling to help processors enhance food safety and operational efficiency.
This episode of Food Safety Five discusses research on Listeria biofilms, including sanitizer efficacy and evolutionary insights, and on a persisting Escherichia coli strain in leafy greens. It also covers regulatory developments in the UK, Canada, and the UAE, as well as a potential U.S. ultra-processed foods (UPFs) definition.
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 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.
This episode of Food Safety Five discusses a new study that leverages a novel quantitative microbial risk assessment (QMRA) model that suggests that half of E. coli O157:H7 illnesses linked to romaine lettuce are caused by contamination via untreated overhead irrigation water.
England saw a 26 percent rise in Shiga toxin-producing Escherichia coli (STEC) infections from 2023 to 2024, and non-O157 STEC cases tripled since 2019. These trends may be driven by one foodborne illness outbreak involving contaminated salad leaves.
Using a newly developed quantitative microbial risk assessment (QMRA) model, researchers have identified interventions along the U.S. romaine lettuce supply chain that would most effectively reduce E. coli contamination. The QMRA is publicly available for use.
