While it would be great if the FDA did something about this, there are probably global dimensions to this problem also. Presumably antibiotics are used globally against strains of disease that spread quite merrily from country to country.
I'd assume epidemiology is not domestically constrained: the antibiotic/agricultural practices of one nation impact all others.
I have no idea what is standard practice for domestic agriculture in my own country. Things I think I "know" about agriculture are distorted through the prism of American cultural influence - documentaries like Food Inc., are writ large in the imagination even where these are only concerned with domestic affairs.
What resources exist that document antibiotic use on a global basis?
