thermometer on fire
I was roasting some cauliflower and squash and after about 10 minutes or so went to check the oven and saw something on fire on the oven floor. I took out the trays and saw it was our oven thermometer that must have fallen on the heating element. The outside rubber (?!) was on fire and half turned to dust. I am now wondering if the smoke from that is A) toxic or bad and B) now a part of my veggies. I would list the brand but I can't read it. It is one thing to poison myself but quite another to poison friends and loved ones who would be eating this food tonight.

Unlike most polymers, silicone does not emit toxic fumes when burned. Silicone + oxygen = silicon dioxide + carbon dioxide + water. (Silicon dioxide is commonly known as "sand".)
Seems like there are more toxic things that go into ovens (oven cleaner), and that while the burning plastic is not a good thing, it probably hasn't hurt anyone yet. The roasted veg is certainly not better for having been exposed, and if it's going to preoccupy you to feed it to other people I would consider discarding it. On the other hand, lots of food has lots more wrong with it! Depends on how purist you are, not whether it's going to kill anyone. (I am, however, not a qualified food scientist in this respect! Good luck.)
