The Facts Behind Your Non-Stick Cookware According To Experts

Non-stick pan


Last year, roughly 70 percent of skillets sold in the United States needed a nonstick coating. It is logical, because nonstick cookware (Teflon has become the most typical) has several significant advantages, like super easy cleanup, not as food sticking into the top, and also the ability to cook with less oil and butter.

Still, many consumers have concerns about toxic compound emissions. Dozens of studies and reports from the business and outside sources have resulted in contradictory conclusions. So we talked to numerous experts, looked over the significant studies, also conducted our own lab tests at the Good Housekeeping Institute to find outside: Just how safe are nonstick cookware?

The solution is an experienced one. They’re safe, says Robert L. Wolke, Ph.D., a professor emeritus of chemistry at the University of Pittsburgh and also the author of What Einstein Told His Cook: Kitchen Science Explained, provided that they’re not overheated. Once they are, the coating can start to break (at the molecular level, which means you’ll not necessarily see it), along with toxic particles and gases, many of those carcinogenic could be released.

“There is a whole chemistry set of chemicals that will come off if Teflon is heated high enough to decompose,” says Wolke. “A number of them are fluorine-containing compounds, including a class that is usually poisonous” However, fluoropolymers, the chemicals from which these toxic compounds come, are a large part of the coating formula — and also the very reason foods don’t stick to nonstick.

If the danger begins when pans over-heat, then hot is too hot? “At temperatures above 500ºF, the breakdown smaller and begins chemical fragments are released,” explains Kurunthachalam Kannan, Ph.D., an environmental toxicologist at the New York State Department of Health’s Wadsworth Center. DuPont, manufacturer, and inventor of Teflon consider that 500°F is the recommended maximum for cooking.

How long does it require a skillet to overheat?

To discover how fast a skillet can reach 500°F (the point at that its coating can begin to decompose), the Good Housekeeping Institute placed three bits of nonstick cookware to the evaluation: a cheap, lightweight pan (weighing just 1 lb., 3 oz.); a midweight pan (two lbs., 1 oz.); and a high-end, heavier pan (two lbs., 9 oz.).

We cooked five dishes at different temperatures onto a burner that is typical in most homes. The results: We were amazed by how quickly a few of the pans got way too hot. Here are the evaluation details to see what we discovered to be secure and risky:

Safe for non-stick:

  • Scrambled eggs 218° F: Cooked on medium for 3 minutes in a lightweight pan
  • Chicken & pops stirfry 318° F: Cooked on high for 5 1/4 minutes at a lightweight pan
  • Bacon 465° F: Cooked on top for 5 1/2 minutes in a medium-weight pan


Risky for non-stick:

  • Empty pan preheated 507° F: Heated on high for 1 3/4 minutes in a skillet
  • Pan preheated with 2 Tbsp. Oil 5-14 ° F: Bite on top for 2 1/2 minutes in a skillet
  • Hamburgers 577° F: Cooked on top for 8 1/2 minutes at a heavyweight pan
  • Steak 656° F: Cooked on top for 10 minutes in a skillet


At very high temperatures — 660° F and — pans might more somewhat decompose, emitting fumes strong enough to induce polymer-fume fever, a temporary flu-like illness marked by chills, headache, and fever (The fumes won’t kill you — however they may kill pet birds, whose respiratory systems are more delicate).

At 680° F, Teflon releases least six toxic gases, including two germs, according to research by the Environmental Working Group, a nonprofit watchdog organization. “However, even when those gases have been formed, the odds that you’re going to breathe enough of them to be sick are low,” says Wolke, a spot corroborated by a number of the experts we interviewed.

What happens when nonstick starts flaking off?

If the butter is more flaking, you might accidentally consume a chip — but don’t be concerned, says Paul Honigfort, Ph.D., a consumer safety officer with the Food and Drug Administration. “A little particle could most likely simply pass through the body, without being absorbed and with no ill effect on the person’s health,” he says.

Also of less concern than formerly thought: the danger of nonstick pans exposing the family to PFOA (perfluorooctanoic acid). A compound used to fabricate the fluoropolymers that makeup non-stick burner’s coat, PFOA is connected with germs and developmental issues in animals, and pros are concerned with its possible consequences on humans.

In 2004, DuPont agreed to cover $343 million to settle a lawsuit alleging that PFOA, utilized in the production of Teflon at a certain plant, had polluted drinking water near. In 2007, a study at Johns Hopkins Bloomberg School of Public Health found an association between PFOA exposure and smallish declines in head circumference and body weight in infants (except people born by cesarean section). The EPA has already reached an agreement with eight organizations, including DuPont, to phase out the use of PFOA completely.

Also worth mentioning is that sources of PFOA are anywhere, not just in nonstick pans made before 2015: From microwave-popcorn bags, fast food packaging, shampoo, carpets, and clothing. Studies indicate that the majority of folks possess PFOA in their bloodstreams, and babies reveal trace amounts at birth. The FDA has also tested nonstick pans to value the risk of PFOA contact with humans. “What we found was the manufacturing process used to produce those pans drives off the PFOA,” says Honigfort,” which means that the compound evaporates. “The danger to consumers is considered negligible.”

How to Safely Use Non-Stick Cookware

You are able to use non-invasive safely, provided that you stick to some precautions to utilize it properly. Any food which cooks quickly on low or moderate heat and coats most of the pan’s face (which brings the pan’s fever) is unlikely to create issues, including foods like scrambled eggs, pancakes, or warmed-up leftovers. And a number of different kinds of cooking are safe as well.

In GHI’s evaluations, the only food preparation that uttered a nonstick pan temperature surpassing 600ºF at less than 10 minutes was beef at a skillet that is lightweight. But to be careful, keep these tips in mind:

Never preheat a vacant pan.

In our evaluations, each of the three vacant non-pans we heated on top reached temperatures above 500 degrees in less than 5 minutes — and the cheapest, most lightweight pan got there in under 2 minutes. Additionally pans with oil in them can be problematic; our cheapest pan zoomed into more than 500 degrees in 2 5 minutes.

Don’t cook at high temperatures.

Most nonstick manufacturers, for example, DuPont, today counsel consumers not to proceed above moderate. (DuPont maintains, however, that Teflon does not pose some health risks, and that its guideline is simply meant to make the most of the life span of the product.) Do people still cook on high, despite manufacturers’ guidelines? “There’s no statistical reply to this query,” says the FDA’s Honigfort. But you know if you’re doing this, of course, if you are, the consensus is pretty clear: It would be safer in the event that you stop. To play it safe, set your knob to either moderate or don’t put your skillet over alleged power burners (anything above 12,000 BTUs on a petrol stove or 2,400 watts within an electrical stove) because those burners are intended for tasks like boiling a big pot of water quickly.

Ventilate your kitchen.

After cooking, turn to the exhaust fan to help clear any fumes.

Do not broil or sear meats.

Those techniques require temperatures above what nonstick can usually handle.

Choose a heavier nonstick pan.

Lightweight pans generally warm up fastest, so put money into heavier-weight pans that can be good for frying. It’s well worth the excess money.

Avoid damaging or stinging the pan.

We’ve been told not to use metal utensils on nonstick pans. Newer products could be harder to process, “as the adhesion between the brow and the nonstick coating is even better,” says Honigfort. Still, if tanks do chip or flake out they may be more inclined to discharge toxic substances, says Kannan of their New York State Department of Health. To prevent scratching, use wooden spoons to stir fry food, avoid steel wool, and don’t stack these pans. (In case you’re doing it, put a paper towel lining between them). How long can you expect your non-stick cookware to last? DuPont’s quote, based on moderate usage, is just three to five years. Many experts, like Kannan, advise replacing your non-stick cookware every couple of years. What do you need to do if the pan will become damaged? A crystal very clear answer, from Kannan: throw out it.
