If farm animals are being fed antibiotics, it’s usually a sign that they’re living in crowded facilities that are likely to make them sick (antibiotics prevent disease) or they're eating an unnatural diet meant to fatten them quickly (antibiotics make animals grow fast).Antibiotics in meat is more of a human health concern than an animal welfare issue (feeding antibiotics doesn't harm animals), but when factory farms ditch antibiotics, they are forced to raise animals a little more naturally, and therefore a little more humanely.  (Note: They can still crowd animals together inhumanely, without enrichments. This is why "antibiotic free" is not one of my 5 recommended labels.)If you want antibiotic-free and humanely raised meat, look for organic labels or humane certification labels.
