Antibiotics and meat don't mix

For the American public's health, it's time for the meat industry to stop administering the drugs preventively but only to animals already ill.

With its blunt warning that antibiotics in meat "pose a serious threat to public health," the U.S. Food and Drug Administration has finally acknowledged what many scientists have been saying for a long time. For years, evidence has been mounting that extensive use of antibiotics in livestock, particularly to promote growth or prevent the spread of disease in crowded pens, has resulted in the development of drug-resistant bacteria.

The issue is not that the meat itself is infected or that consumers are ingesting antibiotics with their protein, but that the overuse of antibiotics is diminishing the efficacy of crucial medications needed for human use. Estimates are that 70,000 Americans each year die from infections that once could be treated with common medications. The European Union has banned the use of antibiotics in livestock except to treat illness, but similar efforts in the United States have stalled in Congress.

So last week, when the FDA issued a "draft guidance" urging meat producers to employ antibiotics judiciously, asking them to voluntarily limit their use to instances of "medical necessity" or to administer them with the oversight of a veterinarian, it was a step forward. Sort of. The occasion can be likened to then-Surgeon General Luther Leonidas Terry formally declaring in 1964 that cigarette smoking was a serious health hazard. That too was an important step forward, and both public health officials and ordinary citizens took note — but tobacco companies spent the next three decades in denial. So the good news is that the FDA's action brings us into the 1960s. The bad news is that the draft has no teeth and proposes no regulations that might become law. What's more, it doesn't discourage the prophylactic use of antibiotics in livestock to prevent disease, which is a big part of the problem. It should have allowed the use of antibiotics only to treat animals that are already sick.

It is difficult to tell where all the stakeholders stand. The American Veterinary Medical Assn. welcomed the FDA's action and vowed to work with the agency. The pork industry questioned the science behind the draft and said that its farmers already use antibiotics judiciously. And the National Cattlemen's Beef Assn. issued a statement asserting that the causes behind drug-resistant infections are complex and solutions should also take into account human misuse of antibiotics.

It's time to take a firmer stand and ban the use of antibiotics except when animals are sick. It's harmful to public health to use antibiotics preventively or to promote growth. The results are in and the science is sound. No longer is the question whether antibiotics in meat farming should be curtailed, but how best to go about doing it.
