Contamination Control

This episode of Food Safety Five discusses expert perspectives on the Healthy Florida First food contaminant testing program, including information gaps about the testing and risk assessment methodology and why this missing information matters.

Incorporating a novel “bio-fumigation” method based on a natural compound produced by mustard plants, the micro-malting machine effectively addresses mycotoxins while preserving quality. USDA is working with industry to scale the prototype for widespread adoption.

Researchers found that the presence of nanoplastic particles can increase the expression of virulence and antimicrobial resistance (AMR) genes in Salmonella, and can also encourage biofilm formation.

In an analysis of domestic refrigerator swabs, researchers discovered complex microbial communities harboring foodborne pathogens and antimicrobial resistance (AMR). The findings also suggested that regular cleaning is possibly more important than temperature control in managing these communities.

Following Codex recommendations for risk-based allergen Precautionary Allergen Labeling (PAL) and thresholds, the European Commission has posted a forthcoming draft act to its public feedback portal on harmonized requirements for the use of voluntary PAL statements.

The scientists will isolate and identify pathogens like Salmonella enterica and Listeria monocytogenes from Pennsylvania wastewater using whole genome sequencing (WGS), then work with the State Department of Health to connect isolates to foodborne illness outbreaks.

Dispersibility may be a useful tool for simulating the spread and hygienic control of allergenic food powders. Researchers recommend that producers add powders from as low a position as possible to reduce the risk of cross-contamination.

FDA has declared the outbreak over with 48 confirmed and probable cases of illness. A root-cause investigation is still ongoing. FDA has also announced new “Operation Stork Speed” infant formula resources for families.

Arachidonic acid oil (AHA oil) from a Chinese supplier was identified as the source of cereulide toxin contamination in infant formula produced by Nestlé and other well-known brands. Imports of Chinese AHA oil are now subject to stricter EU border checks.

With the goal of supporting stronger risk assessments to address emerging food chemical risks, the European Food Safety Authority (EFSA) reviewed existing data sources; data gaps and challenges; and recommendations for improving data availability, quality, and interoperability.
