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.
As in years past, USDA’s Pesticide Data Program reports that more than 99 percent of foods sampled in 2024 were compliant with EPA pesticide residue limits. Some persistent organic pollutants, like DDT, continue to show up in crops.
Two research projects are investigating several novel techniques for detecting hepatitis A virus that eliminate false positives produced by inactivated, non-infectious RNA fragments—an issue that limits the usefulness of existing methods for indicating actual food safety risk.
In a retrospective analysis of two Listeria monocytogenes outbreaks linked to packaged salads, CDC epidemiologists underline key learnings and suggest proactive measures for industry.
Researchers with the Connecticut Agricultural Experiment Station have demonstrated that the use of iron-fortified hemp biochar made from agricultural waste can significantly reduce the amount of toxic PFAS “forever chemicals” taken up by food crops grown in contaminated soil.
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.
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.
