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. 

A recent study investigating Listeria monocytogenes in South Korea’s beef supply chain revealed the presence of the pathogen exclusively in retail product samples, underscoring the importance of strict food safety controls post-harvest. The strains isolated were hypervirulent and stress-adapted.

Since June, FreshRealm has been involved in an ongoing, deadly foodborne illness outbreak, as the producer of prepared pasta meals that were made with Listeria monocytogenes-tainted pasta (supplied by Nate’s Fine Foods Inc.) and distributed nationwide under various brand names. Now, FreshRealm has alerted USDA that it detected L. monocytogenes in spinach used to make meals distributed by HelloFresh.

This article explores the critical yet underappreciated vulnerabilities of ready-to-eat (RTE) foods in retail and foodservice settings, including blind spots in handling practices, supplier-level failures, and the vital importance of reheating protocols and environmental controls.

A CDC analysis of multistate foodborne illness outbreak investigation data for 2023 reveals the foods and pathogens that caused the greatest number of outbreaks and illnesses. A single salmonellosis outbreak linked to cantaloupe accounted for 407 illnesses.

The Congressional Food Safety Caucus, headed by U.S. Representative Rosa DeLauro, has requested that Boar’s Head representatives appear before the caucus to justify the reopening of its Jarratt, Virginia plant, where the meats behind a deadly 2024 Listeria outbreak were produced.

This exclusive eBook presents strategic and collaborative solutions for cleaning and sanitizing your facility. 

This episode of Food Safety Five discusses three recent studies that examine the risk of Listeria monocytogenes growth from multi-species biofilm contamination, how imported seafood may spread antibiotic resistance genes, and a promising AI mycotoxin detection method.

Commissioned by the UK Food Standards Agency (FSA), a survey of prepacked salmon filets sold at supermarkets in the UK showed a low presence of Listeria monocytogenes and Escherichia coli, as well as low levels of antimicrobial resistance (AMR). 

A recent study found that Listeria monocytogenes from multispecies biofilms exhibits higher growth in ready-to-eat (RTE) cold-smoked salmon than L. monocytogenes from single-species biofilms. Additionally, L. monocytogenes contamination from the multi-species biofilm surpassed EU regulatory limits after 15 days of storage.
