1st Study Of Estimated Local Use Of Antibiotics As Livestock Feed Additives Shows 90% Of Estimated Use Concentrated In 23 States
Washington, DC - Almost all (90%) of the 26.5 million pounds of antibiotics estimated to be used in the United States as feed additives each year - seven times the amount used in human medicine nationwide - occurs in 23 states, according to a report released today by Environmental Defense. The report, Resistant Bugs and Antibiotic Drugs: Local Estimates of Antibiotics in Agricultural Feed and Animal Waste, is the first study to provide state and county level estimates of the quantities of antibiotics used as feed additives for chicken, hogs and beef cattle, along with estimates for antibiotics in animal waste. The report is available at www.environmentaldefense.org/go/antibiotic.estimates.

“Studies suggest that people living in areas with intensive use of antibiotics as feed additives are at greater risk of contracting antibiotic-resistant infections,” said Ellen Silbergeld, Ph.D., Professor of Environmental Health Services at Johns Hopkins Bloomberg School of Public Health.

The Environmental Defense report estimates were prepared using new data from the U.S. Department of Agriculture (USDA) on numbers of animals per county, and multiplying those figures by estimates previously developed by the Union of Concerned Scientists (UCS) on the quantity of feed-additive antibiotics consumed per animal. UCS presented national estimates, but not state or county estimates.
“The public has a right to know where antibiotics are being used for nonessential purposes, notably as antibiotic feed additives,” said Environmental Defense senior attorney Karen Florini, co-author of the report. “Unfortunately, no governmental data are available on quantities of antibiotics used in livestock feed either locally or nationally.”
Overuse of antibiotics in agriculture is widely regarded as contributing to the spread of antibiotic-resistant bacteria that threaten human health. Antibiotics are added to feed not to treat sick animals, but rather on the grounds that they may promote slightly faster growth or prevent disease that could result from the crowded, stressful conditions.
“Feeding antibiotics to animals is not only a major cause of antibiotic-resistant bacteria in the human food supply, but also results in the presence of antibiotic-resistant bacteria in animals and in their waste,” said Environmental Defense senior scientist Rebecca Goldburg, Ph.D., co-author of the report. “Those bacteria can in turn colonize and infect farm workers, as well as contaminate water, air, and soil.”
“With antibiotics, the more you use them, the faster you lose them,” concluded Goldburg. “That’s because bacteria become resistant in response to being exposed to antibiotics. Antibiotic resistance is a serious and growing threat to human health, so it’s just plain foolish to be feeding vast quantities of antibiotics to chickens, pigs, and beef cattle.”
The report urges swift enactment of bipartisan federal legislation to phase out use of medically important antibiotics as feed additives, The Preservation of Antibiotics for Medical Treatment Act (S. 742/H.R. 2562), sponsored by U.S. Senator Olympia Snowe (R-ME) and U.S. Rep. Sherrod Brown (D-OH). The bipartisan Senate version of this bill authorizes funds to farmers to help defray costs of phasing out non-therapeutic use of medically important antibiotics, and provides for research and demonstration projects to assist farmers in this transition.
