"A staggering 80 percent of the antibiotics sold in the U.S. are given to farm animals, mostly, as I said, prophylactically: the low-dose drugs help the animals fatten quickly and presumably help ward off diseases caused by squalid living conditions. The animals become perfect breeding grounds for bacteria to gain resistance to the drugs, and our inadequate testing procedures allow them to make their way into stores and our guts."
