Farmers and ranchers will for the first time need a prescription from a veterinarian before using antibiotics in farm animals, in hopes that more judicious use of the drugs will reduce the tens of thousands of human deaths that result each year from the drugs’ overuse.

Just how broadly farmers use antibiotics simply to promote animal growth is unknown. About 80 percent of antibiotics used on farms are given through feed, and an additional 17 percent are given in water. Just 3 percent are given by injection.
