Misuse and overuse of antibiotics is fueling a scourge of drug-resistant infections, a dire threat to public health. While doctors are working to become better stewards of the life-saving medicines, many health experts are taking aim at farms, which soak up nearly 80 percent of the antibiotics sold in the United States.
