If it ain't sick, don't cure it

The Food and Drug Administration (FDA) has announced a restriction on the usage of some antibiotics to prevent illness in farm animals, due to the risk of generating bugs affecting humans, with resistance to drugs. The restrictions will affect cephalosporin usage. Critics argue that cephalosporin accounts for 0.2% of farm antibiotic usage, and are concerned about penicillin and tetracycline usage, which the FDA planned to tackle in 1977. The FDA claims it has focused on voluntary action by farmers, and that it is still concerned about the issue.
