PFAS in 2025: What the FDA's Latest Update Means for Your Food and Health

The U.S. Food and Drug Administration (FDA) has reaffirmed its ongoing guidance on per- and polyfluoroalkyl substances (PFAS), describing them as a large family of human-made chemicals found in a wide range of consumer products. While this isn't a single new bombshell finding, the FDA's updated page serves as a reminder that PFAS monitoring, research, and consumer questions remain very active in 2025. Here's what the agency says, who it affects, and what you can actually do about it.

What Did the FDA Say About PFAS?

According to the FDA, PFAS are a class of thousands of synthetic chemicals that have been manufactured and used since the 1940s. Because of their resistance to heat, water, and oil, they've been widely used in food packaging, cookware, textiles, firefighting foam, and industrial processes. The FDA notes that PFAS can enter the food supply through several pathways, including contaminated soil and water used in agriculture, as well as through certain types of food packaging that may contain these substances.

The agency emphasizes that it continues to test foods as part of its broader monitoring efforts and works with other federal and state partners to better understand where PFAS come from and how people may be exposed through the food supply.

Who and What Is Affected?

Because PFAS have been used so widely for decades, the FDA notes that most people have likely had some level of exposure. Potential sources highlighted by the agency include:

• Certain fast-food wrappers, bakery bags, and microwave popcorn bags that historically used PFAS-based grease-resistant coatings
• Food grown in soil or irrigated with water affected by PFAS contamination
• Fish and seafood from waters with elevated PFAS levels
• Some types of nonstick cookware, though the FDA notes proper use generally limits transfer into food

It's important to understand that detecting PFAS in a product or environment does not automatically mean a health problem will occur. Exposure levels, duration, and the specific type of PFAS compound all factor into potential risk.

Why Does This Matter for Consumers?

PFAS are sometimes called "forever chemicals" because they break down very slowly in the environment and can accumulate in the human body over time. The FDA and other health agencies have pointed to research suggesting associations between certain PFAS exposures and health effects, including changes in cholesterol levels, immune response, and other outcomes. These are described as associations observed in scientific studies, not proof that PFAS directly causes these conditions in every individual.

The FDA states that it evaluates the potential risk of PFAS in the food supply as part of its food safety mission, using the latest available science to guide any necessary actions, such as working with manufacturers to phase out certain uses of PFAS in food packaging.

For consumers, this matters because food packaging, cookware, and water sources are everyday parts of life. Understanding where PFAS may show up—and where exposure has been reduced over the years thanks to voluntary phase-outs and regulatory action—helps put personal risk in context rather than in alarm.

What Can You Do Right Now?

While no one can eliminate PFAS exposure entirely, the FDA and other public health resources suggest several practical steps consumers can take to reduce unnecessary exposure:

• Check your water: If you're on a public water system, request or review your local water quality report, which may include PFAS testing results. Private well owners can consider independent testing.
• Be mindful of packaging: Limit regular use of greasy fast-food wrappers or microwave popcorn bags, especially for hot, fatty foods, which can increase the chance of chemical transfer.
• Care for nonstick cookware properly: Avoid using metal utensils that scratch coatings, and replace pans that are visibly worn or damaged.
• Diversify your diet: Eating a varied diet, including a mix of fish sources, can help limit concentrated exposure from any single contaminated source.
• Stay informed: Because PFAS regulations and testing results continue to evolve, checking updates from agencies like the FDA and EPA periodically can help you make informed choices.

How Are These Findings Determined?

The FDA's assessments rely on chemical testing methods, exposure modeling, and collaboration with other agencies such as the EPA and CDC.

Bottom Line

PFAS remain a widespread and long-lasting group of chemicals in consumer products and the environment, according to the FDA. While their presence in some foods and packaging is considered an area of lower concern when exposure is limited and packaging use is minimized, ongoing monitoring reflects the agency's effort to reduce risk over time. Consumers don't need to panic, but staying informed and making small adjustments—like avoiding certain packaging or checking water quality—can help reduce unnecessary exposure.

Frequently Asked Questions

1. Does the FDA say PFAS in food is dangerous?

The FDA does not label PFAS-containing food as flatly dangerous. Instead, it describes ongoing testing and monitoring to understand exposure levels and reduce risk where possible, treating current findings as an area of lower concern rather than a confirmed hazard for typical consumers.

2. Can I completely avoid PFAS exposure?

Complete avoidance is very difficult given how widely PFAS have been used since the 1940s, according to the FDA. However, consumers can take practical steps, such as limiting certain packaging use and monitoring water quality, to help reduce exposure.

3. Are all PFAS chemicals the same risk level?

No. PFAS include thousands of distinct compounds, and research suggests risk levels can vary based on the specific chemical, exposure amount, and duration. The FDA and other agencies continue to study individual PFAS compounds to refine this understanding.
