High temperatures do not bother Teflon, there's no reason to dispose of it because of that.
According to the EPA Teflon frying pans do not leech any PFOA into food, that's not where people are exposed.
I've noticed that for some reason a ton of people think they get exposure to PFOA from cookware, and that's simply not true. PFOA exposure mainly comes from waterproofing coatings, slippery coatings (like the bottom of skis), and firefighting foam.
Paper dishes (plates, straws, etc) are a big source of exposure because they need to make them waterproof. Make sure to ask for plastic.
- t-3 4y agoLeaching isn't the worry with non-stick coatings, flaking is. Everyone's seen pans flake off teflon into food.
- fzzt 4y agoTeflon is very non-reactive and any small pieces you ingest should pass through unchanged pretty quickly. You likely ingest a lot more plastic from other sources.
- intrepidhero 4y agoOn the other hand, visible flakes of plastic in my food are kind of a bummer.
- pessimizer 4y agoI don't know what's released from Teflon pans at high heat, but Teflon kills birds. I know this because I killed two birds by forgetting about a pan I was warming up. Wasn't enough to make the pan look any different; was enough to instantly kill the birds. https://www.teflon.com/en/consumers/teflon-coatings-cookware-bakeware/safety/bird-safety https://www.teflon.com/en/consumers/teflon-coatings-cookware...
- powerhour 4y agoMy family learned this after replacing a stove with one that had a non-stick interior a couple decades ago. That was a pretty major bummer.
- ars 4y agoI googled, and I could not find any ovens with Teflon in them. On top of that you have to heat the Teflon over 500F / 260C, and ovens temperatures don't go so high (except in self cleaning but a non-stick oven would not have self cleaning). I suspect something else happened to your birds - probably simple smoke from food residue, which kills birds much easier than overheated Teflon does.
- powerhour 4y agoInteresting. IIRC the only thing that changed before and after was the oven was replaced. Ah well.
- mrguyorama 4y agoThis person has been saying all over the thread that "ovens don't go to 500F" and here finally add the actual caveat "except self cleaning". At least half the ovens listed in Lowes's online inventory list self cleaning as a feature, and it's even a feature in my bargain basement level apartment oven, which happily goes up to 550F, which is great for cooking pizza. I don't know whether they're being intellectually dishonest, or genuinely don't realize they're spreading useless info. They're claim that nobody gets a pan hot enough to degrade teflon while cooking is slightly more reasonable, except plenty of recipes start with "heat an empty, dry pan until it is searing hot" and that leaves a lot of room to screw up your pan.
- philipkglass 4y agoI believe that the chemical primarily responsible for bird toxicity from PTFE pyrolysis is perfluoroisobutene: https://en.wikipedia.org/wiki/Polymer_fume_fever https://en.wikipedia.org/wiki/Polymer_fume_fever https://en.wikipedia.org/wiki/Perfluoroisobutene https://en.wikipedia.org/wiki/Perfluoroisobutene Although acutely toxic, this substance is not a persistent "forever chemical" because there are multiple mechanisms that rapidly degrade it in the environment: https://pubchem.ncbi.nlm.nih.gov/compound/Perfluoroisobutylene#section=Environmental-Fate-Exposure-Summary https://pubchem.ncbi.nlm.nih.gov/compound/Perfluoroisobutyle...
