I listened to this interesting story on NPR this morning, Antibiotic Use On The Farm: Are We Flying Blind?
It is undenaible that massive use of antibiotics occurs on the farms and that it is just a given in most agricultural schools of thought this is a necessary and good thing. It probably is necessary if for no other reason than the conditions industrialized agriculture houses animals in, an unnatural and unhealthy environment being fed unnatural feed. The reward at the end for this is "cheap" food for Americans, resulting in American families spending less of their income as a percentage on food than ever before in history.
Is this bad? It it nothing to worry about? I am not sure but even as someone who is not an eco-nut or alarmist I think there are legitimate and serious concerns about the massive and often preemptive use of antibiotics in our food system. The story is brief, give it a listen and see what you think. At the very least it should encourage you to think more about where your food comes from and how it got there.
