Livestock Antibiotic Overuse

I rarely agree with Senator Dianne Feinstein on anything but you won't find me arguing against her effort to limit the use of antibiotics in livestock. I'm not so sure we need to make a literal federal case out of this...or maybe we do?

I've actually been thinking about this fairly often lately. It bothers me that animals are routinely given antibiotics as a prophylactic measure. This not only is believed to lead to diseases resistant to antibiotics, but I don't really like the idea of eating meats full of antibiotics.

I realize most science nowadays seems based on some sort of hysteria, but it seems common sense to me you don't use antibiotics unless really necessary and the bill in question still allows use of antibiotics to treat disease. I'd be interested in hearing arguments against Feisntein's proposal.
