When Household Utensils Attack!
From Crooked Timber:
: Do not, under any circumstances, heat an empty Teflon-covered nonstick pan on the range for more than two or three minutes. At temperatures above 500 degrees (beyond the range of normal home cooking), Teflon will release fumes that cause flu-like symptoms in humans and can be fatal to birds. (No birds were harmed in the preparation of this post. One human, however, feels like he%u2019s been chewed up and spit out of something big.)
