Antibiotic use statistics prove misleading

The oft-cited statistic that 80 percent of antibiotics sold in the United States are used in animals is highly misleading, says Richard Raymond, MD, former undersecretary for food safety at the USDA, in an excerpt published by the Center for Infectious Disease Research & Policy, University of Minnesota.

In a recent Food Safety News (FSN) opinion piece, Raymond writes that the 80 percent statistic is commonly used by those who want to eliminate antibiotic use in animals (because of the risk of promoting resistance to the drugs) and/or reduce the amount of animal products consumed in the United States.

Citing information from a U.S. Food and Drug Administration report, Raymond says 28 percent of antibiotics used in animals are ionophores, which have never been approved for use in humans. Because several other antibiotics used in animals also remain unapproved for human use, a total of 45 percent of antibiotics sold for animal use are not used in human medicine, Raymond writes.

Further, tetracycline is the most commonly used class of antibiotics given to animals, accounting for 42 percent of sales. In human medicine, tetracycline drugs make up only about 1 percent by weight of antibiotics sold.

Thus, Raymond argues, 87 percent of antibiotics used in animals are rarely or never used in humans. He argues against the “radical” step of banning antibiotic use in food animals except to treat actual infections, saying it would markedly drive up the cost of protein.
