The FDA declined a legal request to establish limits for PFAS in food, citing insufficient evidence despite mounting scientific data and an EPA report that food is the largest source of exposure.

Independent testing shows 70% daoine of seafood samples contain PFAS, while 12% of a 50‑sample milk batch tested for the same compounds spiked in brands like Whole Foods. 2019 FDA data dropped from 182 contaminated samples to 78 after a methodology shift, fueling accusations of intentional under‑reporting.

The agency plans only non‑binding “action levels,” which do not mandate removal of contaminated products. Testing technology lags behind water‑monitoring systems, leaving a patchwork of state‑level recalls and industry‑wide uncertainty about contamination routes from pesticides, packaging, and sewage‑sludge fertilization.

For regulators and manufacturers, the decision underscores a need for a comprehensive testing framework. Without binding tolerances, consumers remain exposed to chemicals that can persist for millennia, while public‑health groups push for stricter oversight and clearer standards.
