Unfortunately I think this will only arise if/when we have a major crisis that results in a large amount of Americans being poisoned. We're really, really bad at preventative measures instead opting for short term profit over long term stability and health.

The amount that farms end up poisoning local rivers, streams etc I thought would be enough of a wake up call but I guess I was too optimistic. Organic foods aren't the answer either sadly, since a lot of the time that's the result from unfounded fears.
