Earlier quoted context omitted.
The precautionary principle plus what we know about heating plastic makes your reticence seem churlish. There are easy, safe alternatives in wood, metal and silicone. There’s no need to risk it.
The problem is that even when there are easy, safe alternatives trying to avoid every little risk in your life will drive you crazy. This is a clear case where a regulator should step in and just ban these black plastic utensils in favor of their safe alternatives. That way you're not just protected from exposure in your own kitchen, but also when joining your friends for dinner.
Not really, just avoid them as they come up. Case in point: Throw out your black cooking utensils and use an alt. Simple simple. No crazy to it.
