US FDA rejects petition to set PFAS limits in food

The U.S. Food and Drug Administration has rejected a petition asking it to set enforceable limits for PFAS in food, drawing a line in one of the most closely watched public-health fights over the chemicals known as "forever chemicals."

In a response posted July 8, the agency said the evidence was not sufficient to support mandatory thresholds for PFAS in food. Instead, the FDA said it will rely on non-binding action levels.

The petition came from the Tucson Environmental Justice Task Force, which has been pressing the agency to act on PFAS contamination in food. The group says it plans to sue and ask a court to order the FDA to set thresholds.

How the petition developed

The petition was first filed in November 2023. After the FDA missed its six-month response deadline, the request was narrowed in 2025.

The final version focused on two PFAS compounds, PFOA and PFOS, and on two food categories, seafood and milk. Those are among the foods advocates have pointed to in the broader debate over how PFAS enter the food supply.

The FDA's rejection now leaves the petitioners without the formal limits they sought and keeps the agency on a less enforceable path.

Why advocates pushed for limits

PFAS are widely described as persistent chemicals that do not break down easily in the environment or the body. They are used in products that resist water, stains and grease, and can reach food through pesticides, packaging, sludge used as fertilizer, processing water and other pathways.

The dispute over PFAS regulation has been more advanced in drinking water than in food, even though consumers can also be exposed through what they eat. That gap is part of why public-health advocates have pushed the FDA to set clear standards.

Advocates argue that food should face enforceable limits because the exposure risk remains serious. The FDA's position, in contrast, is that the current evidence does not justify mandatory thresholds.

What comes next

The immediate question is whether the FDA will provide additional technical rationale for its decision or publish draft action levels for PFAS in food.

Another open issue is timing and litigation. The Tucson Environmental Justice Task Force has said it intends to sue, which could push the dispute into court and force the agency to defend its approach.

For now, the decision marks a clear regulatory choice: the FDA is declining to impose mandatory PFAS limits in food while signaling that it will continue with a less enforceable framework.

That leaves consumers, food producers and regulators watching for the next move in a fight that has already become part of the broader debate over PFAS oversight in the United States.
