Limiting the use of antibiotics in factory farming

A startingly high 70% of all antibiotics used in the U.S. are given to livestock. This overuse of antibiotics results in increased bacterial resistance and immunity to their effects, which limits the drugs' usefulness in treating humans.

The Center for Food Safety has an active campaign to urge Congress to impose tighter regulation of antibiotic use for livestock (H.R.6432 and H.R.6433):

Did you know that an estimated 70 percent of all antibiotics used in the United States are regularly added to the feed of livestock and poultry that are not sick--a practice with serious consequences for our health? Bacteria that are constantly exposed to antibiotics develop antibiotic resistance. This means that when humans get sick from resistant bacteria, the antibiotics prescribed by doctors don't work.
