Fester said:Last friday I was "sealing" some chicken in the frying pan. The frying pan was new. The Spatula was a black plastic. The spatula actually left stains on the frying pan where it had melted; I ate the chicken and it was delicious.

If the point is other potential sources of plasticizer may be hard to weed out, thereby making it impossible to form conclusions based on a +ive for plasticizer, I get your drift. BUT I'd be surprised if spatulas (e.g.) contain the same plasticizer used in blood bags. There are many different kinds of plasticizers:
Given there are many different kinds, I wonder how specific the plasticizer test is? Does is detect a specific compound, or a group of compounds? If only good down to the group level, that might make a possible scenario like the one you suggested more plausible and difficult to refute.
