Re “The High Cost of Cheap Meat” (editorial, June 3), about the looming public health danger posed by the overuse of antibiotics on factory farms, an issue I’ve been working on for years:

The Food and Drug Administration must take steps to reduce the needless use of antibiotics in healthy animals and preserve their effectiveness for human beings.

Unfortunately, House Republicans are threatening to cripple the F.D.A.’s ability to keep our food safe and to regulate tobacco — along with a whole host of other public health threats — through an agriculture appropriations bill this year.

It is time for Congress to stand with scientists, the World Health Organization and the American Medical Association and take action to prevent the spread of resistant bacteria. The long-term public-health costs of returning to an era before antibiotics are simply too high to ignore.
