Top-tier antibiotics need to be reserved for humans. Absolutely. Obviously, overuse of any antibiotics in huge populations of humans or animals leads to bacteria evolving resistance... for a random event in a trillion, it ends up being a pretty determinstic fact, just like neutron decay. It doesn't necessarily follow that using 2nd or 3rd tier antibiotics in limited cases in animal populations is always unwarranted, so long as we're aware of the potential for resistance and we're developing new ways to counter it. You have to play the cards you're dealt. Yes, the elimination of mass meat farming would go a long way toward preventing the adaptation of novel resistant bacteria. The situation, though, is that this type of farming will continue to happen for a long time. Regulations should prohibit the overuse of antibiotics, without completely preventing their use.
