Researchers in China have developed a new onsite rapid test, based in fluorescence RNA-targeted isothermal amplification assay (SAT) technology, that can quickly detect and identify Cronobacter species in powdered infant formula. It offers significantly greater sensitivity and much more rapid results than polymerase chain reaction (PCR), without producing false positives.
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.
A laboratory study and large-scale commercial wheat mill trial demonstrated that a bacteriophage cocktail can significantly reduce Shiga toxin-producing Escherichia coli (STEC) O157:H7 contamination throughout milling operations without affecting the baking qualities of flour.
According to the 2025 International Food Information Council (IFIC) Food and Health Survey, consumer confidence in U.S. food safety has hit an all-time low in the 13 years since the survey began gauging the metric. Foodborne bacteria are the number one ranked concern in 2025, and attention to food additives and ingredients is rising.
A foodborne listeriosis outbreak in Ireland has sickened nine people and resulted in one death. Preliminary investigation results suggest the likely cause are ready-to-heat meals produced by Ballymaguire Foods, sold under a variety of brand names at major retailers. Recalls have been initiated in Ireland and Northern Ireland.
FDA and CDC have closed their investigation into a Listeria outbreak linked to ready-to-eat products produced by Fresh and Ready Foods of San Fernando, California, announcing that one of the ten people who fell ill has died.
A study of Salmonella isolated from retail poultry meat has demonstrated a concerning presence of antimicrobial resistance (AMR) genes with the ability to transfer between bacteria.
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.
Federal support for state-level foodborne illness surveillance programs, directed by the U.S. Centers for Disease Control and Prevention (CDC), significantly improves participating states’ detection and reporting of foodborne illness outbreaks, a new study demonstrates.
