Teflon, PFOA, PTFE and PFAS are not the same thing. But the relationship between them makes the non-stick pans we use in the kitchen far more important than we might think. Moreover, the issue is not just about pans and pots; thousands of chemicals called PFAS can be found in the environment, drinking water, food, textiles, carpets, firefighting foams, and numerous industrial products.
So is Teflon really harmful? Why was PFOA banned? Can a pan labeled “PFOA Free” still contain PFAS? What happens when a PTFE coating is scratched? And most importantly: What is the situation in Turkey? The answers to these questions are far more complex than the two extreme narratives found online: “Teflon is poison” or “PTFE is completely harmless.”
PFAS, PFOA, PTFE and Teflon are not the same thing
Let’s start with the most important distinction.
PFAS is a large chemical family encompassing thousands of synthetic fluorinated chemicals.
PFOA (Perfluorooctanoic acid) is one of the small molecules in this family. It was historically used as a processing aid in fluoropolymer production.
PTFE (Polytetrafluoroethylene) is a fluoropolymer used in non-stick coatings.
Teflon™ is a commercial brand associated with certain non-stick products, primarily PTFE.
The critical point here is this: PFOA ≠ PTFE but: PTFE is also within the PFAS family.
The polymer chain of PTFE is roughly –CF₂–CF₂–CF₂–CF₂–. This means that having “PFOA Free” written on a product does not automatically mean “PFAS Free.” This distinction is extremely important for consumers.
If it says “PFOA Free,” is the matter settled?
No. PFOA FREE means the product does not contain PFOA. This statement alone does not indicate that the product is free from all PFAS. Because PTFE itself is a PFAS fluoropolymer. Therefore, having PFOA FREE written on a coating is not the same thing as having PFAS FREE written on it.
Moreover, because the PFAS family is so large, replacing PFOA with another chemical does not automatically mean that all health and environmental problems have been eliminated.
Why is PFOA such a serious substance?
We have stronger data on PFOA than an ordinary chemical debate. The World Health Organization’s cancer research agency IARC classified PFOA in 2023 as: “Carcinogenic to humans” – Group 1.
In the IARC evaluation, there was limited epidemiological evidence in humans for renal cell cancer and testicular cancer; additionally, experimental animal studies and mechanistic evidence in human cells supported the classification. There is an important scientific distinction here: The “carcinogenic” classification does not mean that everyone exposed will develop cancer. IARC evaluates the hazard of a substance to cause cancer. The actual risk depends on the amount of exposure, duration, and route of exposure. PFOS, on the other hand, was classified in the same evaluation as “possibly carcinogenic to humans” – Group 2B.
So what does PFOA do to the human body?
In epidemiological research on PFAS, associations between certain substances and various health outcomes have been reported. Particularly in the C8 Health Project, which investigated high PFOA exposures, research was conducted on outcomes such as high cholesterol, thyroid diseases, kidney and testicular cancers. However, here too, it is not correct to evaluate all PFAS as a single substance.
Saying “PFAS = definitively causes all these diseases” is scientifically too general. The more accurate statement is: There is significant scientific evidence that some PFAS are associated with serious adverse effects on human health, and PFOA is one of the most extensively studied examples.
What happens if you scratch a PTFE pan and swallow a particle?
There is an interesting situation here. PTFE is a highly inert polymer. If small PTFE particles that break off from the coating are accidentally swallowed, they are expected to pass through the digestive system largely unchanged. Therefore, the issue is not: “I swallowed a tiny PTFE particle that broke off from the pan, so I’m definitely poisoned.” However, this information should not be interpreted as a safety recommendation for continuing to use a scratched or damaged coating. Because a significant part of the PFAS issue is not only the ingestion of solid PTFE particles.
One of the actual critical points: high temperature
PTFE coatings can be quite stable under normal use conditions. However, when an empty pan is heated to very high temperatures, the situation changes. The German Federal Institute for Risk Assessment (BfR) states that PTFE coating can degrade at temperatures of approximately 360 °C and above, and health-hazardous gases can form.
Moreover, these gases do not always have to appear as visible smoke. Therefore, overheating empty PTFE-coated cookware is especially important. The rapid rise in temperature on gas and induction stoves is also additionally important for control.
The problem here is this: How many people in the kitchen connect a thermocouple to the pan and constantly measure its temperature? Consumers often cannot visually distinguish between 300 °C and 400 °C. Therefore, the statements “safe under normal use” and “safe under all conditions” should not be confused with each other.
Was PFOA found on pans sold in Turkey?
Here, when the subject comes to Turkey, a very important scientific study emerges. In a study published in 2022, 35 PTFE-coated non-stick pan and pot samples available on the market in Turkey were examined. Researchers investigated perfluorinated compounds and some primary aromatic amines using the LC-MS/MS method.
The result was striking: PFOA was detected in 6 of the 35 samples.
The study also observed that migration increased with rising temperature. This result does not show that all PTFE pans sold in Turkey today contain PFOA. The study examined a certain number of samples and products available on the market during a certain period. However, the fact that PFOA migration in PTFE-coated cookware sold in Turkey has been investigated and detected in some samples shows that the issue is not entirely theoretical for our country.
What was the DuPont case and PFOA/C8?
When attorney Robert Bilott began investigating environmental pollution allegations thought to be linked to DuPont facilities near a farm in West Virginia, the matter extended to PFOA/C8. Documents that emerged during the lawsuit revealed a very large body of information accumulated over the years about the environmental spread of PFOA and its possible effects on human health.
The U.S. Environmental Protection Agency (EPA) later imposed sanctions on DuPont regarding information reporting related to PFOA/C8. In 2005, DuPont reached an agreement with the EPA including a $10.25 million civil penalty** and **$6.25 million in environmental projects. In subsequent years, health data and blood samples from approximately 70,000 people were collected under the C8 Health Project. These studies later became an important data source for examining the relationships between PFOA and various health outcomes.
There is also an important legal detail here: It is not correct to simplify it as DuPont accepted all these allegations. For example, although a large settlement covering thousands of personal injury cases was reached in 2017, companies going to settlement does not mean that all scientific or legal claims were accepted.
Why did Europe restrict PFOA?
In the European Union, serious restrictions on PFOA and PFOA-related substances came into force as of July 4, 2020. However, let’s correct a very important misunderstanding here: The European Union did not ban all Teflon pans in 2020. Restrictions were introduced on the production, placing on the market, and use of PFOA and certain PFOA-related substances.
However, Europe’s PFAS policy did not end there. On the contrary, Europe is currently working on a much broader restriction that could cover the entire PFAS family. In 2023, a comprehensive PFAS restriction proposal prepared by Denmark, Germany, the Netherlands, Norway, and Sweden was submitted to ECHA. In 2026, the scientific committees of the European Chemicals Agency made important evaluations on this proposal.
So the approach in Europe is gradually moving from the question: “How do we control only PFOA?” to the question: “How do we reduce the spread of thousands of PFAS into the environment and to humans?”
Why are some U.S. states banning pans?
In Minnesota, as of January 1, 2025, the sale of certain products with intentionally added PFAS was banned, and the scope includes cookware. In Minnesota’s official statement, Teflon™ is directly defined as PTFE within the PFAS family. In Maine, the sale of cookware products with intentionally added PFAS was banned as of January 1, 2026.
Maine’s definition covers not only pans and pots but also baking sheets, molds, trays, bowls, and some kitchen utensils. The fundamental rationale for these bans is not only “poisoning from a pan.” The persistence of PFAS, its spread in the environment, its accumulation in water and soil, and its ability to reach humans through different exposure routes are at the center of broader environmental policy.
Is PFAS only in the kitchen?
No. The real big issue starts here. Substances in the PFAS family have historically been used or are being used in:
Non-stick coatings,
Water- and stain-repellent textiles,
Carpets,
Food packaging,
Firefighting foams,
Electronics and semiconductor applications,
Aviation and aerospace industry,
Gaskets and technical parts,
Some medical applications.
The important characteristic of PFAS is that carbon-fluorine bonds are very strong. Therefore, they do not easily break down in the environment. As a result, the issue cannot be reduced to just a pan in the kitchen:
Production → waste → soil → groundwater → drinking water → food chain → human
We are talking about a much larger environmental problem that progresses in this way.
What is being done in Turkey today?
In Turkey, there is no situation like “PFAS doesn’t exist.” With the Turkish Food Codex Communiqué on Sampling and Analysis Method Criteria for Official Control of Perfluoroalkyl Substances in Certain Foods published in 2025, official control and analysis methods were regulated for PFAS in certain foods:
PFOS,
PFOA,
PFNA,
PFHxS.
In other words, PFAS contamination in foods in Turkey is now the subject of the official control system. However, the important difference is this:
Currently in Turkey, there is no regulation banning the general sale of PTFE non-stick pans and pots containing intentional PFAS, as in Minnesota or Maine.
Therefore, the situation in Turkey is: not “PFAS is not controlled at all”; however, it is also not “PFAS-containing non-stick cookware is directly banned.” The difference between these two sentences is very important.
Conclusion: The issue is not just Teflon pans
The clearest conclusion that can be drawn from the scientific data we have today is this:
PFOA and PTFE are not the same substance.
PTFE is a fluoropolymer within the PFAS family.
PFOA is a separate PFAS chemical and has been classified as carcinogenic to humans by IARC.
The statement PFOA FREE does not mean PFAS FREE.
Overheating PTFE coating, especially in an empty pan at temperatures of approximately 360 °C and above, can lead to the formation of health-hazardous decomposition gases.
In a study conducted on PTFE-coated cookware sold in Turkey, PFOA was detected in 6 of 35 samples.
All of this does not lead us to the conclusion that “every PTFE pan definitely poisons humans.” But likewise, it does not lead to the conclusion: “Teflon is completely harmless, PFOA is no longer present, you can use it however you want.”
Especially because PFAS are extremely persistent in the environment, the issue is not only the effect of a pan we use today on our health. The issue is;
Where the chemicals entering our homes come from, where they go, and what they leave to the generations after us.
Therefore, more transparent product labeling, stronger migration controls, independent tests, and stricter regulations centered on human health must continue to be discussed regarding PFAS. Because consumers now need to know that a product labeled “PFOA FREE” and a “PFAS FREE” product are not the same thing.
And perhaps the most important question is this:
If it is known that a chemical is this persistent in terms of human health and the environment, how much longer should we wait to remove it from as many areas of our lives as possible?
