but it will be localized farm environment only..

Its just question of risk/benefit ratio, benefit is clear: cheap meat, because producers will be less impacted by deceases. Risks are not so clear in this case.

It doesn't stay localized; runoff from farmland is a major issue. In other words, the farm animal poops out a bunch of antiobiotics, then it rains and that poop ends up washing into the river/lake/water table. That's already something that happens with situations like E. coli contamination. Things that happen on the farm don't stay on the farm.

Ok, still focus could be not on avoiding antibiotics completely, but preventing runoff, or finding types which decay faster in environment.

Do we know even if we can build sustainable large scale industry without antibiotics?
