FDA's Study Finds PFAS in Food; Urges Urgent Federal Regulations

New FDA Research Highlights PFAS Presence in Food Products

The U.S. Food and Drug Administration (FDA) recently released findings from its ongoing Total Diet Study (TDS), shedding light on the presence of per- and polyfluoroalkyl substances (PFAS) in our food supply. This comprehensive study aims to assess the levels of contaminants and essential nutrients in various food items, amidst rising concerns over food safety and public health.

During the 2024 phase of the study, a total of 542 food samples, ranging from salmon and chicken breast to kale, were analyzed. Remarkably, more than 92% of these samples displayed no detectable PFAS levels. However, approximately 7% did present trace amounts of these substances, with specific seafood samples—four out of 39 tested—showing elevated concentrations.

The FDA's commitment to testing plays a crucial role in determining average PFAS exposure levels and refining future monitoring and regulatory strategies. Since the program's commencement in 2019, findings have consistently indicated that 95% of examined fresh and processed foods contain no detectable PFAS.

While the FDA asserts the importance of their data collection, they caution that “TDS data can show how much contamination is present and help estimate possible exposure, but they should not be used on their own to decide whether something is safe or harmful to health.” This nuanced understanding of the data aims to prevent misinterpretations about food safety.

PFAS, which are synthetic chemicals used widely in consumer goods and industrial applications, are known for their persistence in the environment and potential health hazards, including links to cancer. In a related development, the Biden administration's Environmental Protection Agency (EPA) has mandated the first federal limits on PFAS in drinking water, although these regulations are currently under review by the Trump administration.
