Is Teflon toxic when scratched?

Author: Adan Boyle  |  Last update: Wednesday, July 1, 2026

Broken or scratched Teflon coating could lead to the release of thousands to millions of plastic particles, a study suggests. The coating may shed microplastics and PFAS, also known as forever chemicals. Exposure to PFAS has been linked to health risks including liver disease and kidney cancer.

Is it safe to use scratched Teflon?

Scratches in metal and non-stick (teflon) pans are fine. If you scratch up a non-stick (teflon) pan just use it like a regular metal pan. If the non-stick (teflon) materiel starts to flake off use a brillo pad to take the rest of the non-stick off.

Is Tefal toxic when scratched?

Is it dangerous to cook in a scratched pan? TEFAL non-toxic cookware products are designed to be long lasting without deteriorating. However, inadvertently swallowing a piece of the coating is quite harmless.

Are old Teflon pans safe to use?

Should I throw out old Teflon pans?

Nonstick Pans Do Not Last Forever

A good rule of thumb is to replace them approximately every five years.

The Truth About Nonstick Cookware: Teflon

Does Teflon still contain PFAS?

Conventional nonstick cookware is made with a PFAS called PTFE (polytetrafluoroethylene), also known as Teflon. In the past, PTFE was produced with the help of another PFAS called PFOA. But studies clearly linked PFOA to health risks, so this specific chemical was phased out in 2014.

Should I throw away my scratched non-stick pan?

We advise replacing your nonstick pans whenever the coating starts to degrade or is scratched—or about every three to five years.

When did TEFAL stop using Teflon?

Tefal Pans Are Not Made With TEFLON™

Historically, Tefal used TEFLON™-branded coatings for its non-stick pans. However, when Groupe SEB acquired Tefal in 1968, it chose to internalize the production of its own non-stick coatings to better control and manage all stages of production.

Does Calphalon use Teflon?

Teflon® is a registered trademark of DuPont and a brand name for polytetrafluoroethylene (PTFE) a nonstick finish. While Calphalon cookware features polytetrafluoroethylene-based nonstick finishes, we are not associated with, nor do we use, Teflon® branded products.

Why was Teflon banned?

Concerns and Considerations

Environmental Impact: The manufacturing process of PTFE can lead to the release of harmful substances like PFOA, a type of PFAS. Health Risks: While PTFE is stable, overheating it can release fumes that might cause flu-like symptoms in humans, sometimes referred to as "Teflon flu."

What is the difference between PTFE and Teflon?

Essentially, the only difference lies in the name. PTFE is the shortened name of the chemical polytetrafluoroethylene, and Teflon is the trade name of the same polymer. If you are looking for a highly flexible, non-stick material that is chemical, electrical and thermal resistant, look no further than PTFE.

Is PTFE absorbed by the body?

PTFE is too large and too insoluble to be absorbed by organisms - PFOA, PFOS and PFHxS are readily absorbed by organisms that eat/drink contaminated food/water.

What is the best non-toxic cookware?

Is it safe to wear Teflon?

Safety of Teflon™ Textile Finishes

In fact, the U.S. Environmental Protection Agency (EPA), does not believe there is any reason for consumers to stop the routine use of products made with PFCs including nonstick cookware and products such as breathable, all-weather clothing.

Do air fryers have Teflon?

Most air fryer baskets are coated with Teflon or a similar nonstick coating. The majority of air fryers in the market today have Teflon or nonstick-coated cooking baskets. They function similarly to nonstick cookware in that they release food easily and can be cleaned often with just soapy, hot water.

Are scratched TEFAL pans safe?

A surface scratch on Teflon coating may shed more than 9,000 micro- and nanoparticles, potentially contaminating food with harmful chemicals, according to a study by researchers from the Global Centre for Environmental Remediation.

When did Calphalon stop using Teflon?

A: Calphalon stopped manufacturing our nonstick using PFOA back in the third quarter of 2012. We have then since moved to a formula that is completely FDA approved.

Is Teflon safe now?

More than 50 years of consumer use, along with laboratory testing and published peer-reviewed research, has affirmed that cookware made with Teflon™ nonstick coatings is safe for both consumer and commercial use at normal cooking temperatures. Myth: Nonstick coatings wear off easily.

Is it bad if my family uses scratched nonstick pans?

No. While they don't necessarily present a safety concern, you still shouldn't hold onto your scratched nonstick pans.

Is PTFE carcinogenic?

The International Agency for Research on Cancer reviewed the research on PTFE, and determined the current data was inconclusive with regard to PTFE's potential to cause cancer. However, a wide-ranging literature has linked PFOA, which can be a contaminant of PTFE-containing consumer products, to health effects.

Is PFAS in parchment paper?

Because PFAS are so ubiquitous, trace amounts make their way into products without manufacturers intentionally adding them. Parchment paper and other food-grade paper products that contain fewer than 100 parts per million (ppm) of PFAS are generally considered to have no intentionally added PFAS.

Why do we no longer recommend GreenPan?

Then, we removed GreenPan entirely from our list of non-toxic cookware. There were two primary reasons: Competing brands began providing independent laboratory testing to prove their products are non-toxic. We became aware of lawsuits against GreenPan that cast doubt on the company's marketing claims.
