FDA Rejects Petition to Establish Pfas Limits in Food Amid Growing Health Concerns

The U.S. Food and Drug Administration (FDA) rejected a petition on November 2023 that sought to set limits on toxic Pfas "forever chemicals" in food, a decision that disappoints public health advocates. The petition highlighted that food is the primary source of chemical exposure, as identified by the Environmental Protection Agency (EPA).

Background on Pfas and Food Safety

Pfas, a class of over 16,000 compounds, are utilized for their water-, stain-, and grease-resistant properties. They have been linked to severe health issues including cancer, birth defects, and kidney disease. Despite extensive research indicating that food poses a significant risk, the FDA has opted not to establish regulatory limits.

The Tucson Environmental Justice Task Force (TEJTF), which filed the petition, plans to sue the FDA to enforce limits. Attorney Sandra Daussin stated, "If it’s important enough to regulate in water then we need to regulate it in food – that’s a no-brainer."

FDA's Testing and Findings

Recent FDA testing revealed that 70% of seafood samples contained Pfas. Independent tests found contamination in 12% of milk samples, including significant levels in brands like Whole Foods and Kirkland Signature. The FDA's response stated there is "insufficient evidence" to support the TEJTF's request, opting instead to set non-binding action levels.

Testing methods for food contamination have lagged behind those used for water, complicating the assessment of the issue. Independent studies indicate high levels of Pfas in various foods, including blueberries and kale, which are particularly susceptible due to their water content.

The Implications of Inaction

Regulating Pfas in water but not in food leaves consumers vulnerable to health risks. Daussin emphasized that, "Your body doesn’t know how the Pfas got in there." The FDA's limited testing methodology has drawn criticism, as evidenced by a significant drop in reported contamination levels after a change in testing procedures.

• 182 food samples initially found contaminated in 2019
• Number dropped to 78 after methodology changes
• High levels of Pfas found in seafood, milk, and various produce

The growing body of evidence demands a more rigorous approach to testing and regulation, as public health advocates continue to push for stricter oversight of Pfas in the food supply.
