Testing & Analysis

The list includes kits validated for Salmonella, Campylobacter, Listeria, and Escherichia coli.

This episode of Food Safety Five discusses new academic publications exploring the limitations of a “zero-risk” approach to food safety and evaluating the limited benefits and trade-offs associated with intensified microbiological sampling.

The third Science Meets Policy conference will take place September 2–3 in Rome, Italy, focused on helping EU competent authorities and industry members effectively implement new WGS data-sharing requirements for foodborne pathogens.

Sponges far outperformed cotton swabs in laboratory experiments and real-world sampling in an RTE food production facility. The findings align with existing recommendations supporting the use of sponge-based sampling with neutralizers for environmental monitoring.

The updated Microbiology Laboratory Guidebook chapter on whole genome sequencing (WGS) of bacterial isolates now includes protocols for using both the Illumina MiSeq and MiSeq i100 sequencing platforms.

Using metagenomic sequencing and qPCR, the study analyzed bacteria from produce, chicken meat, and RTE deli meats sold at retail stores in Tennessee. A high abundance and diversity of antibiotic resistance genes were identified, potentially contributing to the persistence and spread of antimicrobial resistance (AMR) in the food supply.

Unlike many other foodborne pathogens, Listeria can both survive and grow at refrigeration temperatures. This ability, along with the risk of cross-contamination to other foods and surfaces, contributes to its persistence in food processing environments and makes it a significant concern for food safety.

The Canadian Food Inspection Agency (CFIA) recently published the findings from several food sampling and testing assignments for microbiological and chemical contaminants across a range of food categories. In general, the results were satisfactory.

A JEMRA meeting was convened to help inform discussions about potential updates to Codex Alimentarius guidance, reflecting how scientific advances could strengthen microbiological risk assessments for food safety.

The Environmental Working Group’s 2026 Shopper’s Guide to Pesticides in Produce highlights PFAS pesticides for the first time. Although EWG recently updated its methodology, scientists argue it still does not consider key exposure science and risk assessment principles, therefore misleading consumers about the health risks of conventionally grown produce.
