Some plastics are more stable than others. That said, we are admittedly far too lackadaisical with them in general.

To answer your direct question, we do have an FDA that does a passable job with some things, salmonella outbreaks, emergency vaccine development, stuff like that. There is probably some regulatory capture at play, though, where business interests get their people appointed into oversight roles. When a full half of our government is so vocally and rabidly pro-business, this is difficult to prevent in the long run.
