Contamination Control

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.

The researchers conducted environmental sampling throughout a controlled environment agriculture (CEA) operation and tested swabs for L. monocytogenes. Boot covers proved to be a useful tool for evaluating the effectiveness of cleaning and sanitation.  

The first set of results focuses on acrylamide and certain toxic heavy metals. Although the levels of some contaminants in food are decreasing overall, the population's exposure still remains concerningly high.

EPA repealed Biden-era amendments that had tightened emissions regulations under the Mercury and Air Toxics Standards (MATS) rule. Critics warn that this decision could lead to greater bioaccumulation of the neurotoxin methylmercury in fish, increasing human dietary exposure.

A new study quantified the allergen cross-contamination that occurs in shared frying oil and evaluated the efficacy of different filters in removing allergen protein residues from oil.
