If it's Teflon / PTFE, as long as you don't let it smoke you should be fine. The polymer chain is too large to enter your cells, so your body just expels them intact.

That's not to say you should go out and buy everything coated in PTFE. It generates tons of pollution when it's synthesized. I'm just saying there's no need to rush to throw away the ones you may already have at home - that might be counter-productive as you're now generating waste unnecessarily.
