EPA has announced its sixth Contaminant Candidate List, which includes PFAS, microplastics, pharmaceuticals, disinfection byproducts, and other chemicals and microbes. Concurrently, HHS unveiled its Systematic Targeting Of MicroPlastics (STOMP) initiative to address and understand microplastics in the human body.

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.

WHO assessed the overall public health risk as “moderate,” citing the vulnerability of infants, uncertainty around the extent of contamination, and gaps in surveillance and traceability.

Recent contamination incidents involving moringa products draw attention to supply chain vulnerabilities that affect many botanical ingredients used in the global natural health industry. These events offer an opportunity to examine where problems can emerge and how companies can better protect consumer safety.

A literature review conducted by Greenpeace concluded that heating food in plastic packaging—even ready-to-heat meals labeled as “microwave-safe” or “oven-safe”—may significantly increase the migration of microplastics and chemical additives into food.

The researchers positioned the machine learning model as a low-cost complement to traditional testing workflows, helping dairy processors enhance food safety while targeting laboratory resources.

Of the 111 “Generally Recognized as Safe” (GRAS) additives identified by the Environmental Working Group (EWG), 49 are known to be widely used by food manufacturers.

However, concerning levels of arsenic and lead were detected in some products, and Consumer Reports is therefore urging FDA to set limits for these metals in infant formula. PFAS were also found in more than a quarter of products.

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.
