If you’ve ever looked at the ingredient list on a snack bar and thought, “Wow, that’s a lot of syllables,”
welcome to the modern food erawhere the scariest thing isn’t always what’s in the food, but what
quietly gets into the food. Enter PFAS: a huge family of “forever chemicals” that don’t break down
easily, move through water and soil, and can wind up in places they were never invited… like your lunch.

In August 2025, Public Employees for Environmental Responsibility (PEER) announced a petition urging the
Make America Healthy Again (MAHA) Commission to treat PFAS in the food system like the “we-should-not-be-eating-this”
problem it is. The petition’s argument is blunt: you can’t promise a healthier America while allowing multiple
industrial pathways to deliver PFAS into the food chain at scale.

PFAS in Plain English: Why “Forever” Is Not a Compliment

PFAS (per- and polyfluoroalkyl substances) are a large group of human-made chemicals used for decades because they’re
excellent at resisting heat, grease, stains, and water. That’s great if you’re designing a raincoat, less great if
you’re designing a bloodstream. Some PFAS accumulate in the body over time. Research and public health agencies have
linked certain PFAS exposures to health concerns such as immune effects, changes in cholesterol, and increased risks
for some cancersespecially when exposure is higher or sustained.

The hard part is not understanding that PFAS can be harmfulit’s tracing how they travel. PFAS don’t need to be
directly sprinkled onto food to show up in it. They can ride along through fertilizer, packaging, industrial processing,
pesticides, contaminated water, and runoff. The PEER petition focuses on three specific pathways it says are both major
and fixable: biosolid fertilizers, fluorinated plastic containers, and pesticides.

Who Is PEERand Why Petition the MAHA Commission?

PEER is a nonprofit known for supporting environmental and public health professionals and for pushing agencies to follow
scientific evidence and legal mandates. In this case, PEER aimed its petition at the MAHA Commissiona federal commission
created to address chronic disease drivers and improve health outcomes. In the petition and related materials, PEER argues
that the MAHA effort discussed PFAS primarily in the context of drinking water but did not adequately address PFAS pathways
into food.

The timing matters. PFAS regulation has been accelerating across multiple agencies and states, with increasing attention on
exposure routes beyond drinking waterespecially when chemicals can move into milk, meat, fish, produce, and pantry staples.
PEER’s pitch to MAHA is essentially: “If you’re serious about health, you can’t treat food contamination like a footnote.”

The Petition’s Core Claim: Three PFAS Pathways Into the Food Chain

PEER’s petition highlights what it describes as three “regulatory failure” channels that allow PFAS to reach people through food.
Think of them as three conveyor belts delivering unwanted chemistry to your plate. The petition’s solution is not magicit’s
governance: define PFAS consistently, close loopholes, and use agency authority to cut off preventable exposure.

1) Biosolid Fertilizers: When “Recycling Nutrients” Comes With a Side of PFAS

“Biosolids” is the polite term for treated sewage sludgesolid material separated during wastewater treatment. In theory, it can
be nutrient-rich and used as fertilizer or soil amendment. In reality, wastewater is where many industrial and household chemicals
end up, including PFAS. Wastewater treatment plants generally weren’t built to remove PFAS effectively, meaning sludge can become a
concentrated holding tank for persistent contaminants.

PEER argues this is one of the most direct routes from industrial chemical use to farm fields and, eventually, to food.
The petition cites estimates that a significant portion of U.S. agricultural land uses sludge-based fertilizers and that tens
of millions of acres may be affected. It also points to real-world cases in which PFAS contamination was detected in animal tissue
and local food products following nearby sludge applicationsexactly the kind of “surprise ingredient” nobody wants.

This isn’t just an abstract risk model. When biosolids are applied to land, PFAS can move into soil and water and may be taken up by
plants or consumed by livestock. That can lead to contamination in milk, meat, eggs, and fish. Even if broad national supply impacts
are hard to quantify, localized contamination can be devastating for farmers, ranchers, and communitiesfinancially and emotionally.
Once PFAS are in soil, remediation can be extremely difficult and expensive.

2) Fluorinated Plastic Containers: Packaging That Can Create PFAS

The petition’s second pathway is less “farm field” and more “industrial process.” Certain plastic containers are treated through a
fluorination process to improve barrier propertieshelping containers resist chemical degradation or leakage. PEER argues that this
process can create PFAS (including PFOA) in the container surface and that those PFAS can leach into contents.

The reason this belongs in a food-chain conversation is simple: some of those containers hold substances that touch food or become
part of food processinglike edible oils and flavoringsor they hold agricultural chemicals that later contact crops. In other words,
even when PFAS aren’t “added,” they may be unintentionally generated and then transferred into materials that travel through the food system.

PEER has also pursued litigation and advocacy on this issue, arguing that regulators should not treat PFAS created through fluorination as
a minor technical detail. To consumers, it’s not technical. It’s the difference between “food-grade supply chain” and “why does my salad dressing
need a chemical origin story?”

3) PFAS in Pesticides: “Forever” Meets “Spray It on Strawberries”

The third pathway might be the most head-snapping: PFAS in pesticides. PEER points to peer-reviewed research described as a comprehensive review
of how PFAS can appear in pesticide productssometimes because PFAS are intentionally added (to improve stability or performance), and sometimes
because PFAS can leach from fluorinated containers.

Pesticides are applied widely across U.S. agriculture, and residues can appear on crops or move into nearby soil and water. If PFAS are present
in pesticide formulations or packaging, this becomes another route for environmental dispersion and potential human exposure. PEER’s broader point is
not that all pesticide use equals PFAS exposureit’s that PFAS-containing pesticides (or PFAS contamination in pesticide supply chains) should not be
normalized, ignored, or waved away with “don’t worry about it” energy.

What PEER Wants MAHA and Federal Agencies to Do

The petition’s recommended actions are pragmatic and bureaucratic in a good waylike finally labeling the breaker box before the house catches fire.
PEER calls for a uniform, government-wide definition of PFAS (including a definition used by multiple authorities and states, according to the petition)
and for agencies to use their regulatory, procurement, and grant-making powers to eliminate support for products and practices that channel PFAS into food.

In practice, that could mean:

• Biosolids: Stronger federal action on PFAS in sewage sludge used as fertilizertesting, limits, disclosure, and potentially restrictions where needed.
• Containers: Tightening oversight of fluorination practices that can generate PFAS and ensuring safer alternative barrier technologies are used.
• Pesticides: Identifying PFAS-containing products, closing definitional loopholes, and restricting or canceling approvals that introduce PFAS into agriculture.

One important nuance: definitions and regulatory interpretations of “what counts as PFAS” can be contentious. Different agencies and stakeholders sometimes
draw lines differentlyespecially around chemicals that contain fluorinated carbons but may not behave like classic long-chain PFAS. That debate is precisely why
PEER is pushing for a consistent definition: without it, you can end up regulating a fraction of the problem while the rest keeps strolling into the food system
wearing a fake mustache.

How This Collides With Real Life: Farmers, Food Brands, and Shoppers

PFAS policy can sound like a Washington-only drama until you see who pays the bill when contamination is discovered. Often it’s not the chemical manufacturer
or the wastewater generatorit’s the farmer whose land can’t be used, the dairy that can’t sell milk, the family told not to eat the fish in their local lake,
or the county that suddenly needs emergency support.

For farmers and ranchers, the biosolids pathway is especially alarming because it can create contamination through “approved” practices. A farmer may apply a
legally marketed soil amendment and later learn that PFAS moved into water, animals, or crops. That can trigger testing, lost contracts, livestock impacts, and
years of uncertainty. It’s not just a health story; it’s a business continuity story.

For food brands, PFAS concerns are increasingly a supply-chain risk. Even if a brand doesn’t use PFAS directly, suppliers may face PFAS issues through water,
fertilizers, packaging, or agricultural chemicals. Risk management may require more testing, vendor standards, and documentationespecially for products like dairy,
meat, eggs, and seafood where localized contamination events can be consequential.

For shoppers, PFAS exposure reduction isn’t as simple as “buy organic” or “avoid one ingredient.” PFAS are environmental contaminants that can show up through
multiple routes. That said, changes at the system levelclosing pathways, improving monitoring, and reducing PFAS at the sourcecan lower overall exposure without
turning grocery shopping into a chemistry final exam.

Where the Science and Policy Conversation Is Heading

Recent federal and state actions suggest a growing willingness to treat PFAS as a long-term environmental health challenge, not a short-term PR headache.
Some PFAS have been targeted with drinking water standards and cleanup frameworks. Food-related oversight is also evolving. Federal agencies have expanded testing methods,
and recent public updates show a push to better understand where PFAS are detected in foods and what levels may matter.

Meanwhile, biosolids are becoming a flashpoint. Regulators have acknowledged risks for people with higher exposures through locally produced foods in impacted areas.
Even when agencies say “the broader food supply is not at risk,” localized exposure is still a serious public health and economic issueespecially for communities
relying on local agriculture, home gardening, hunting, or fishing.

PEER’s petition is best read as an attempt to force coordination: drinking water rules alone won’t solve PFAS exposure if other pipelines keep flowing. If the MAHA Commission
wants measurable health improvements, it needs to treat PFAS as a cross-agency food-system problemnot a single-agency water problem.

What Readers Can Do Without Losing Their Minds

If you’re not in charge of a federal agency (and if you are, hello, please return my calls), there are still practical steps to consider:

• Stay informed locally: PFAS risk can be highly regional. Pay attention to state advisories on fish consumption, agricultural contamination, and drinking water.
• Ask smart questions: If you buy from local farms, it’s fair to ask about soil and water testing programs in your regionespecially in areas with known contamination.
• Support transparency: Policies that require disclosure and monitoring of PFAS in biosolids, pesticides, and food supply chains help everyone make better choices.
• Focus on upstream fixes: The biggest wins come from preventing PFAS from entering wastewater and industrial processes in the first place.

Most importantly, don’t let the complexity lull you into resignation. PFAS are difficult, yesbut many pathways are identifiable and preventable. PEER’s petition is a
reminder that “forever chemicals” shouldn’t get forever access to the food system just because the paperwork is inconvenient.

Real-World Experiences Related to PFAS in the Food Chain (Added Section)

People often talk about PFAS like they’re invisible villainsand they arebut the lived experience is surprisingly tangible. It starts with a phone call, an email,
or a test result that changes your relationship with everyday food.

The farmer’s experience: One of the most repeated themes in reported contamination cases is shock. Farmers who used legally marketed soil amendments
have described feeling blindsided when PFAS testing shows up in soil, water, or animal products. Even before any health conclusions are reached, the business impact can
be immediate: buyers pause orders, processors ask questions, and everyone suddenly wants documentation that didn’t exist a month ago. The emotional toll is real, too.
Farming is often multigenerational, and the idea that land can be contaminated for years feels like an inheritance being rewritten in real time.

The county and community experience: Local officials and residents in affected areas often end up playing detective. They’re trying to figure out what
happened, which practices were involved, and who has authority to fix it. Communities may push for emergency declarations, testing programs, and financial support.
Meanwhile, neighbors swap practical advicelike whether it’s safe to eat eggs from backyard chickens or fish from a nearby creekbecause official answers can take time.
The uncertainty can fracture trust: people wonder whether agencies knew, whether companies disclosed enough, and whether “it’s within guidelines” is actually comforting.

The food company experience: For brands and processors, PFAS becomes a supply-chain audit nightmare. Not because every product is contaminated, but because
the risk is distributed: water sources, farm inputs, packaging, and even industrial handling can matter. Quality teams may expand vendor questionnaires, tighten specifications,
and add targeted testing. Some companies describe a shift in mindsetfrom “PFAS is an environmental story” to “PFAS is a procurement story.” That’s not glamorous work, but
it’s how big systems change: one vendor standard at a time.

The shopper’s experience: Consumers rarely get a clear “avoid this one thing” instruction. Instead, they get a mosaic: PFAS in water, PFAS in some food packaging,
PFAS in certain hot spots, PFAS in fish advisories, PFAS in headlines that sound alarming but don’t explain the dose. The most common feeling is fatiguefollowed by the
realization that systemic prevention matters more than perfect personal avoidance. People want regulations that reduce exposure without requiring everyone to become an amateur
toxicologist before breakfast.

Taken together, these experiences explain why the PEER petition emphasizes closing pathways. It’s not just about chemicals; it’s about preventing the moment when a family,
a farmer, or a community discoverstoo latethat “forever” also means “hard to undo.”

Conclusion

PEER’s petition to the MAHA Commission frames PFAS exposure as a food-chain issue with three major, addressable entry points: sewage sludge-based fertilizers, fluorinated
plastic containers that can generate and leach PFAS, and pesticide products and supply chains that may contain PFAS. Whether you come to this topic as a public health advocate,
a farmer, a regulator, or a person who simply enjoys eating without chemical surprises, the takeaway is the same: preventing PFAS from entering the food system is far easier
than cleaning it up after the fact.
