Limiting antibiotic use in farm animals will help reduce antibiotic resistance

The U.S. Food and Drug Administration has ruled that farmers must limit the use of antibiotics called cephalosporins to prevent infections in seemingly healthy cows, pigs, chicken, and turkeys. According to the FDA, 24.6 million pounds of antibiotics are used each year in cattle, pigs, chickens, and turkeys purely for the sake of prevention. This practice has contributed to the development of antibiotic-resistant bacteria, which are a growing threat to human health. Doctors often prescribe cephalosporins to stop common infections such as pneumonia and urinary tract infections. They are also used before surgery. Unfortunately, more and more infections are resistant to cephalosporins. Doctors are being asked to prescribe antibiotics only when they are most needed. Farmers should do the same thing. Otherwise, antibiotics lose their power. Bacteria strains become drug-resistant. And people suffer.
