(I don't really agree with either viewpoint I'm just trying to explain the argument)
Bioaccumulation of harmful substances as we rise through the food chain is a known issue.
Using our best antibiotics to produce 60 billion chickens per year is a state financed suicide and not at all a free market mechanism.
What I don't understand is how the unregulated shipment of of a antibiotic from one country (where it is controlled) for a chicken industry in another country (one of whom was actually bought by pharma company in India) to increase profits of both private companies is "state financed suicide and not at all a free market mechanism". It sounds exactly like laissez faire capitalism exploitation due to bypass of state regulation.
I'm sure you'd rather your romaine not come with a free side of E. coli.
If the majority of the food supply is tainted, your choices from within it doesn't affect the rest.
