How Much PFAS Should Be Allowed in the Food We Eat?

FDA Rejects Petition to Set PFAS Limits in Food: What the Decision Means for Consumers and Food Safety

It’s a simple question. Yet today, there is no clear federal standard that answers it.

In June 2026, the U.S. Food and Drug Administration (FDA) issued its final response to a citizen petition requesting enforceable limits for certain PFAS chemicals in specific foods. The agency declined to establish the requested tolerances and action levels, concluding that the available evidence did not support adopting the proposed standards at this time, while emphasizing that it continues to study PFAS exposure and potential future regulatory actions.

The decision has renewed an important national conversation.

PFAS, often referred to as “forever chemicals,” can move through the environment in ways that are difficult to contain. Industrial contamination can affect water, soil, and agricultural land, creating pathways for certain PFAS to enter crops, livestock, seafood, and ultimately the food people eat. The FDA recognizes these pathways and continues to study how environmental contamination contributes to dietary exposure.

The question is no longer whether PFAS contamination can reach the food supply.

The question is whether our regulatory system should establish clear, science-based standards that define when contamination becomes unacceptable.

AVA Law Group represents the Petitioners in legal action arising from the FDA’s response to the citizen petition. The legal process will address important questions about regulatory responsibility, food safety, and the role of science in protecting public health. We’ll continue sharing updates as the case moves forward.

Key Takeaways

• The FDA has denied a citizen petition requesting enforceable PFAS tolerances and action levels for certain foods.
• PFAS can enter the food supply through contaminated water, soil, and agricultural inputs, including biosolids.
• The FDA maintains it can address contaminated food on a case-by-case basis but has not adopted the clear nationwide standards requested by the Petitioners.
• The decision has moved the issue into the next phase of the legal process.
• The broader policy question remains: Should the United States establish clear, science-based PFAS limits in food?

What Are PFAS?

Per- and polyfluoroalkyl substances (PFAS) are a large group of synthetic chemicals that have been used for decades in industrial processes and consumer products because of their resistance to heat, water, and oil.

Their durability has also become their greatest concern.

Many PFAS break down very slowly in the environment, allowing them to persist in water, soil, and living organisms over time. Scientific research has associated exposure to certain PFAS with a range of potential health effects, leading federal and state agencies to expand research into how people are exposed and how those exposures can be reduced.

How Can PFAS Enter the Food Supply?

Environmental contamination does not stop where pollution begins.

PFAS can enter the food supply through contaminated soil, irrigation water, groundwater, and biosolids applied to agricultural land. Crops grown in contaminated areas may absorb certain PFAS, while livestock and seafood may also be exposed through contaminated feed or water.

This pathway illustrates why PFAS is not solely an environmental issue.

It is also a food safety issue. Contamination can originate far from a grocery store or dinner table. A release from an industrial source today may eventually affect farmland, fisheries, or other parts of the food production system years later.

This is why consistent scientific evaluation and effective regulatory oversight matters.

Why Did Petitioners Ask the FDA to Set PFAS Limits?

Federal law provides mechanisms that allow the FDA to establish standards for certain contaminants in food.

The regulatory showdown was initiated in November 2023 when the Tucson Environmental Justice Task Force filed a comprehensive legal petition compelling the FDA to mandate testing for up to 30 distinct PFAS compounds across a wide spectrum of daily staples, including produce, fish, eggs, milk, and bread. When the agency missed the statutory six-month response deadline, the task force strategically narrowed their request in 2025.

The revised petition specifically asked the FDA to establish immediate advisory thresholds for PFOA and PFOS, the two most extensively studied and statistically dangerous variants of the chemical class, specifically targeting commercial seafood and fluid milk products.

The request reflected a straightforward principle.

When contamination has the potential to reach the food supply, clear standards can help provide consistency for regulators, food producers, and the public alike.

Why Did the FDA Decline the Request?

The FDA explained in its response that it shares the goal of protecting the public from harmful PFAS exposure but concluded there was insufficient evidence to establish the specific tolerances and action levels requested in the petition. The agency also noted that scientific understanding of PFAS continues to evolve and stated that it is gathering data that could support future regulatory actions for some products.

Importantly, the FDA did not conclude that PFAS contamination in food is unimportant. Instead, it determined that the record before it did not justify adopting the requested standards at this time.

That distinction matters because the conversation is not simply about whether the FDA has authority to act. It is about when that authority should be exercised through clear, publicly defined standards.

What Protections Exist Today?

The FDA  continues to monitor contamination in the food supply.

The agency has developed testing methods, analyzed thousands of food samples, assisted states investigating contamination, supported product recalls when appropriate, and used import controls to prevent certain contaminated food products from entering the United States.

Those efforts demonstrate that PFAS contamination is taken seriously.

However, responding to contamination after it is identified is different from establishing clear standards that define acceptable levels before problems arise.

What Happens Next?

The FDA has issued its final response to the citizen petition.

That decision now moves the matter into the next phase of the legal process. Clear regulatory standards can provide consistency for everyone involved in the food system. They help regulators determine when action is appropriate, give producers a better understanding of compliance expectations, and provide the public with greater transparency about how food safety decisions are made.

AVA Law Group represents the Petitioners in litigation arising from the FDA’s response and will continue advocating for accountability through the legal system while sharing developments as the case progresses.

Regardless of the outcome, the conversation surrounding PFAS in food is likely to continue as scientific research expands and policymakers evaluate future regulatory options.

Looking Ahead

PFAS contamination presents complex scientific, legal, and regulatory questions. Addressing those questions requires thoughtful leadership, transparent decision-making, and a willingness to evaluate whether existing regulatory approaches continue to meet today’s public health challenges.

As this legal process moves forward, AVA Law Group will continue to share updates and developments.
