Can Nonstick Cookware be Toxic?
While easy to clean and good for low-fat cooking, Teflon and similar brands of nonstick cookware can release a toxic chemical called PFOA (perfluorooctanoic acid) when overheated.
This has prompted the US Environmental Protection Agency to urge companies to phase out the use of PFOA in manufacturing processes.
PFOA is used to make fluoropolymers, which are the basis for Teflon and other brands of nonstick surfaces, as well as a range of oil- and water-repellent coatings for carpets, furniture, leather and food packaging.
Although Teflon is considered safe under normal cooking conditions, it can release PFOA fumes when temperatures exceed 260°C, as the coating breaks apart. Alarmingly, after just two to five minutes on a conventional hot plate, cookware coated with Teflon can exceed 300°C, according to the Environmental Working Group, an independent consumer organisation.
While there is no direct evidence of harm to humans, animal studies show that PFOA can cause reproductive problems, enlargement of the liver, negative effects on the brain, immune suppression and even cancer.
Two studies reviewed by the European Food Safety Authority found that PFOA exposure in pregnant women was linked with reduced birth weight.
Another from UCLA School of Public Health found women with high levels of PFOA and another chemical in their blood took longer to fall pregnant.
Since PFOA has been detected at low levels in 98 per cent of Americans’ blood and 100 per cent of newborns, and it takes years to eliminate, the Environmental Working Group believes we should look for safer ways to prevent food from sticking.
5 tips for using nonstick pans
1. Use stainless steel instead, with a little oil, juice or water.
2. Invest in cast iron, which develops a natural nonstick surface with time, or try the enamelled variety, which is instantly nonstick.
3. If you love Teflon, never preheat it dry and use only low or medium heat.
4. If the nonstick coating cracks, chips or bubbles, throw out the pan.
5. Make sure an exhaust fan or window is open during cooking.

Add CommentA good alternative is NEOFLAM cookware which is free of PFOA and PTFE. It looks like Teflon but isn't. Heats up evenly on a low heat and is non stick even without oil. See their website. Quite pricey but well worth it. I have no interest in the company but think it is an excellent product.
Non stick cookwares made off Teflon are bad for your health, if used at high temperature.Teflon has a substance called Carcinogen.This can lead to cancer. But non stick cookwares which are made from Ecolon are safe as it is made off 100% natural materials. Neoflam cookwares are made from Ecolon.
After trying a few other potential solutions, this was the one that did the trick because My wife is systematically discarding all of our Teflon-coated pots, pans and utensils in response to a perceived concern that Teflon is a health risk.
