How careful do I need to be about nonstick pan fumes?

Hi Avian Vet,
I'm one of those bird owners that probably errs on the side of overly cautious- I don't take any chances with my lovebird. I'm wondering about the use of nonstick cookware. I personally don't use it, but I've just moved in with a roommate who does. If my bird stays in another room with the door shut and windows cracked, do I need to be concerned? If the pans are overheated and do release a toxin, how potent is it? Thanks for your help.
