I was in the midst of browning meat for a stew recipe with my Le Creuset pot. I finished the first batch of meat and removed it from the pan, and then took my new nonstick oxo tongs to the pan to remove some of the darkened stuck meat bits to prevent burning.
Then I looked at the nonstick tongs and realized that about 1/4 of the tip had melted off, and that there was blackened plastic all over the pan! Then there was lots of smoke! Then the fire department arrived.
After the nice fireman left, I browned the rest of the meat and onions in a different pan while I scrubbed out the Le Creuset. Unfortunately, now there is dark marking on the bottom of the pan and some minor flaking. I got it pretty clean though- the inside of the pan was smooth to the touch, but then I continued on with the recipe (it's still going).
We've got the windows airing out the kitchen, but I'm worried that the meal might now contain some toxic plastic. The meat never came into contact with the melted tongs, but if toxic chemicals are still in the Le Creuset or somehow penetrated it (there were a bunch of tiny shallow pin-sized holes in the enamel after I finished cleaning) that I'm going to eat poison.
