As of December 2, laboratory-confirmed cases in the ongoing Salmonella outbreak linked to pistachios has reached 155, and CFIA now requires importers and manufacturers of Iranian pistachios to hold and test their products for Salmonella before they can be sold.
This episode of Food Safety Five discusses a farm-to-fork quantitative microbial risk assessment (QMRA) for Listeria monocytogenes in cantaloupe, a study demonstrating the efficacy of antimicrobial peptides for reducing Salmonella in poultry, and the adoption of new international standards at the 48th session of the Codex Alimentarius Commission.
An ongoing project funded by the Center for Produce Safety is investigating ways to increase the antimicrobial activity of food-grade waxes, which are commonly applied to fruit and vegetables to extend shelf life.
A laboratory study has provided new insights into the efficacy of peroxyacetic acid (PAA) and chlorine dioxide against Escherichia coli, Listeria monocytogenes, and norovirus in wash water during potato processing, and investigated cross-contamination risks in batch washing and water reuse scenarios.
Researchers have developed a new, farm-to-fork quantitative microbial risk assessment (QMRA) model to evaluate the risk of Listeria monocytogenes contamination in fresh-cut cantaloupe.
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.
The Canadian Food Inspection Agency (CFIA) has enacted regulatory amendments with the goal of reducing red tape regarding labeling, traceability, and imports
for fresh fruit/vegetable producers and the poultry/egg industries—specifically, hatcheries.
The Center for Produce Safety (CPS) has announced six new research projects totaling $1.8 million to address critical food safety challenges in the fresh produce industry.
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.
