Quick take

  • PTFE, the plastic-like coating best known as Teflon, is itself a PFAS, according to Germany’s risk-assessment agency and Minnesota’s pollution-control agency.23
  • “PFOA-free” names one chemical. Both Consumer Reports and the Ecology Center warn it does not mean a pan is free of PFAS.67
  • Nobody can test for “all PFAS” at once. Every “free” claim sits on a specific test, with limits, or on no test at all.6
  • Minnesota, Maine and Colorado now restrict cookware that contains intentionally added PFAS. That is a rule about how products are made, not a lab certificate for any single pan.8910

What counts as a PFAS

PFAS stands for per- and polyfluoroalkyl substances. It is a large family of synthetic chemicals, and it has no single universal legal definition. The U.S. Food and Drug Administration’s December 2025 report notes there is “neither a consensus definition of PFAS internationally nor a federal definition in the U.S.”1 That report uses the 2021 definition from the OECD: fluorinated substances containing at least one fully fluorinated methyl or methylene carbon atom.1

State laws use their own wording. Minnesota and Maine both define PFAS as fluorinated organic chemicals containing at least one fully fluorinated carbon atom.89

Why this matters when you shop: “PFAS-free” can mean different things depending on who is using the phrase and which chemicals they checked.

PTFE is a PFAS

Polytetrafluoroethylene (PTFE) is the polymer most commonly used for nonstick pan coatings. Germany’s Federal Institute for Risk Assessment (BfR) states that PTFE “belongs to the chemical group of per- and polyfluoroalkyl substances (PFAS).”2 Minnesota’s Pollution Control Agency says: “Teflon™ is the trademarked brand name for one member of the PFAS family, polytetrafluoroethylene (PTFE)… As a PFAS, Teflon™ will be prohibited from use in cookware.”3

BfR also notes that making PTFE coatings involves other substances, including emulsifiers, some of which are non-polymeric PFAS, and that the baking-on (sintering) step removes or tightly binds most of the leftover starting and auxiliary substances.2 Related coating polymers named by BfR include ETFE, PFA and FEP.2

Other trade names exist. The Ecology Center’s testing identified several coating names printed on pans (QuanTanium, Granitestone, DuPont Autograph and Greblon) as PTFE.7 A brand name on the box is not a reliable guide to what the coating is.

What agencies and researchers say about risk

This is where honest sources disagree, and where marketing tends to flatten the picture. We are summarizing, not judging.

See the evidence: what each source says about risk
Source What it says Context
U.S. FDA Since the 1960s it has authorized specific PFAS-containing substances for food-contact use, including nonstick coatings. For pots and pans it says the manufacturing process vaporizes off virtually all smaller, migratable PFAS molecules, and “studies show negligible amounts of PFAS in this coating can migrate to food.”4 Federal rules list perfluorocarbon resins that “may be safely used” in food-contact articles, subject to conditions such as extractability limits.5
BfR (Germany) When used as intended, the amounts potentially released “are so small that no adverse health effects are to be expected.” Overheating an empty pan to around 360 °C and above can release gases hazardous to health.2 BfR says it has no experimental data of its own on transfer into food, and that its conclusion reflects the current state of knowledge.2
Consumer Reports Experts it consulted do not think an intact PTFE pan is likely to expose you to significant PFAS levels, but a scratched or degraded pan may be less safe, and PFAS in pans also raise environmental concerns from manufacturing and disposal. It also says growing research suggests many compounds used to make the coating may pose health risks.6 CR’s chemist says avoiding PFAS in pots and pans “may help protect your health and the environment.”6
Ecology Center PTFE coatings have been known to release hazardous chemicals when heated, especially above 400–500 °F. It calls the human-health effects of those emissions “not entirely understood,” and says research is “not definitive” on swallowed bits of scratched coating.7 An environmental nonprofit. It frames the issue around PFAS pollution across a pan’s lifecycle (manufacture, use, disposal).7

Put plainly: the sources above do not claim that an intact PTFE pan used correctly has been shown to harm the person cooking with it, and they do raise concerns about overheating, worn coatings, and the environmental footprint of PFAS production and disposal. People who choose to avoid PFAS in cookware are usually acting on precaution and on those lifecycle concerns. That is a reasonable personal standard, and it is the one this site is organized around. It is a standard, not a proven health outcome.

“PFOA-free” is not “PFAS-free”

PFOA is one PFAS.

A “PFOA-free” label says that one chemical was left out of that pan’s coating. It does not say anything about the other PFAS.

See the evidence: what the tests found
  • The Ecology Center, which identified coatings on 24 nonstick pans in 2020, reported that “most pans labeled ‘PFOA-free’ were coated with PTFE without clearly indicating that.”7
  • Consumer Reports tested a PTFE-coated pan (Swiss Diamond) whose package said PFOA-free. It reported an average of 4 parts per billion of PFOA in the coating and measurable levels of 16 of the 96 PFAS it looked for.6 The U.S. distributor challenged CR’s results. It said PFOA-free raw materials had been used since 2007 and that cross-contamination in testing was possible. CR said it took precautions against cross-contamination, including testing its equipment, and found no PFOA in that check.6
  • Consumer Reports says it has stopped displaying “PFOA-free” in its nonstick cookware ratings because the claim may not be reliable for PTFE-coated products.6

The Ecology Center also reports that after PFOA manufacturing in the U.S. was reportedly phased out, a similar chemical, GenX, was often substituted.7

Materials: what the evidence covers

The table covers what tests exist, not a ranking. See the materials comparison for more detail.

See the evidence: what the tests cover, material by material
Material What the sources say What we could not find
PTFE-coated nonstick A PFAS by BfR’s and MPCA’s description.23 —
Ceramic-coated nonstick (marketed as PTFE-free) In CR’s 2022 test, two ceramic-coated pans (Our Place Always Pan and Red Copper) had none of the 96 PFAS it looked for. CR notes other PFAS could theoretically be present.6 In the Ecology Center’s coating analysis, the two pans labeled PTFE-free had a silicon dioxide (“ceramic”) coating, matching their labels.7 Tests of other brands or newer production runs. These results cover specific pans bought at specific dates.
Uncoated stainless steel, cast iron, carbon steel CR says many uncoated pans, including carbon steel and cast iron, are also “unlikely to contain PFAS.”6 The Ecology Center lists stainless steel and cast iron among durable alternatives that avoid PTFE’s lifecycle concerns.7 Both sources’ lab tests looked at nonstick pans. We found no published PFAS lab results for specific uncoated pans. The expectation rests on how those pans are made, not on a test.
Enameled cast iron The Ecology Center lists it as another option “often marketed as nonstick.”7 No PFAS test of enameled cookware found.
Glass The Ecology Center lists glass among options for baking.7 No PFAS test of glass cookware found.

How claims are tested, and the limits

A claim is only as strong as the test behind it, and every method here has limits.

How we know: the testing methods and their limits
Method What it can tell you Limits
Coating identification (FTIR spectroscopy). Used by the Ecology Center: it scraped bits of coating off each pan and identified the coating’s composition.7 Whether a coating is PTFE, silicone/polyester, silicon dioxide (“ceramic”), BPA-based epoxy and so on. This is how it showed that some labels did not match the coating.7 The Ecology Center says it tested only the coating type. It did not test for PFOA, GenX or other PFAS chemicals used in manufacturing and possibly remaining in finished products.7
Targeted PFAS panel. Used by Consumer Reports: coatings scraped from 30 samples of each of three pans were tested for 96 PFAS.6 Which of those 96 specific chemicals were or were not detected in the sampled coating, and at what level. CR’s chemist notes there are thousands of PFAS but most tests look for fewer than a hundred. “Free” may also mean below a set level, not zero.6 Three pans is a small sample.
Total fluorine screen. A general method that measures fluorine in a product. A broad signal that fluorine is present. The FDA states that total fluorine analysis “only analyze[s] for fluorine in a product and cannot discern between the presence of PFAS or the presence of other non-concerning fluorine containing substances.”4 California’s AB 1200 uses a threshold of 100 parts per million of total organic fluorine to define regulated PFAS in plant-fiber food packaging, which is not cookware.11
Manufacturer testing on request. Minnesota’s commissioner can direct a manufacturer to provide test results within 30 days when there is reason to believe a product contains intentionally added PFAS.8 If testing shows no intentionally added PFAS, the manufacturer must give the commissioner a certificate saying so, with the results.8 We found no public database of these certificates. This is a compliance mechanism, not a consumer-facing label.

A single clean result does not make a brand’s whole line clean. Any serious claim should say who tested, which method and which chemicals, when, and on which product. See how we evaluate claims.

State laws: Minnesota, Maine, Colorado (and California’s labeling rules)

Several states now restrict cookware sold in their state if it contains intentionally added PFAS. Summaries below come from the statutes themselves. They are not legal advice, and laws change, so check the originals.

See the evidence: the state rules, side by side
State Cookware rule Notes from the text
Minnesota Beginning January 1, 2025, a person may not sell, offer for sale or distribute for sale cookware that contains intentionally added PFAS.8 “Cookware” includes pots, pans, skillets, grills, baking sheets, baking molds, trays, bowls and cooking utensils.8 “Intentionally added” means deliberately added where the PFAS’s continued presence is desired to perform a function.8 The 2025 ban does not cover PFAS only in electronic or internal components.8 The MPCA says products with PFAS only in such components fall under a separate 2032 prohibition instead.3
Maine Effective January 1, 2026, a person may not sell, offer for sale or distribute for sale a cookware product containing intentionally added PFAS.9 “Intentionally added PFAS” also includes degradation by-products. Used products are exempt. Retailers are not covered by the prohibition unless they have received a state notification that a product’s sale is prohibited.9
Colorado On and after January 1, 2026, a person may not sell, offer for sale, distribute for sale or distribute for use in the state cookware that contains intentionally added PFAS chemicals, including in an internet listing or transaction.10 The act defines cookware so that it excludes food equipment intended primarily for commercial settings.10 We read the signed 2024 act and have not checked for later amendments.
California (labeling, not a ban) AB 1200 requires cookware makers to disclose certain chemicals and bars “free of” claims for a chemical in a listed group unless that chemical was not intentionally added.11 The California Attorney General’s 2023 advisory says the rule applies to chemicals on a state “designated list” that is intentionally included in the handle or any food-contact surface. Website disclosure began January 1, 2023 and label disclosure January 1, 2024.11

What these laws do not do. They regulate what manufacturers may deliberately add and sell. They do not certify that any individual pan has been tested or contains zero PFAS. Minnesota’s own definition rests on intent: PFAS “deliberately added” to perform a function.8 A pan can be legally on sale in these states and still have no public test result behind it. We make no claim about how closely any brand or retailer complies, and we have not verified whether any of these laws is being challenged.

What to do with this

  1. Treat “PFOA-free” as a prompt to ask “what is the coating?”, not as an answer. See the label decoder.
  2. If you want a nonstick surface and want to avoid PTFE, look for a product that states the coating type plainly. Both CR and the Ecology Center say a PTFE-free claim on a ceramic-coated pan is more informative than a PFOA-free claim.67
  3. If you will cook at high heat, consider uncoated materials. See the materials guide.
  4. For a registry, work material-first. See the kitchen registry guide.
  5. If you own a PTFE pan, BfR’s advice is not to heat it empty and not to overheat it. CR advises against metal utensils and steel wool.26

What we don’t know

  • Whether any particular pan is free of PFAS. We do not test products, and only a few have public lab results.
  • Test results for brands beyond those cited. CR’s and the Ecology Center’s results apply to the pans they bought, in 2020–2022.
  • How states are enforcing their cookware laws, and whether other states have added restrictions. We covered Minnesota, Maine, Colorado and California only.
  • Whether coatings sold as “ceramic” contain other substances of concern. The sources cited address PFAS and PTFE.
