Research on Antibiotics

1. According to the Union of Concerned Scientists, an estimated 70% of antibiotics in the U.S. are used on animals.

Executive Summary:

Antimicrobial resistance is a public health problem of growing urgency. Although use of antimicrobials in humans is the largest contributor to the problem, use of antimicrobials in agriculture also plays a significant role. Mounting evidence is confirming the view, long held in the public health community, that antimicrobial use in animals can substantially reduce the efficacy of the human antimicrobial arsenal.

Now is the time to act to curb the overuse of antimicrobials in animals. But as public health officials and citizens turn to this task, data on quantities of antimicrobials used are not publicly available, even though these data are critical to designing an effective response to the problem.

This report attempts to fill in that gaping chasm by providing the first transparent estimate of the quantities of antimicrobials used in agriculture. We have devised a methodology for calculating antimicrobial use in agriculture from publicly available information including total herd size, approved drug lists, and dosages. The method is complex but sound, and the results are startling. We estimate that every year livestock producers in the United States use 24.6 million pounds of antimicrobials for nontherapeutic purposes. These estimates are the first available to the public based on a clear methodology. We have been careful in making these estimates, always choosing conservative assumptions. We hope that any critics of this study who claim the estimates are incorrect will provide the documented data needed to refine them.

2. “Antibiotic resistant enterococci and staphylococci isolated from flies collected near confined poultry feeding operations,” Science of the Total Environment (January 2009)

Researchers at the Johns Hopkins Bloomberg School of Public Health found evidence that houseflies collected near broiler poultry operations may contribute to the dispersion of drug-resistant bacteria and thus increase the potential for human exposure to drug-resistant bacteria. The research was funded by a grant from the Johns Hopkins Center for a Livable Future.

The findings demonstrate another potential link between industrial food animal production and exposures to antibiotic resistant pathogens. Previous studies have linked antibiotic use in poultry production to antibiotic resistant bacteria in farm workers, consumer poultry products and the environment surrounding confined poultry operations, as well as releases from poultry transport

Jay Graham and his colleagues collected flies and samples poultry litter from poultry houses along the Delmarva Peninsula-a coastal region shared by Maryland, Delaware and Virginia, which has one of the highest densities of broiler chickens per acre in the United States. The analysis by the research team isolated antibiotic-resistant enterococci and staphylococci bacteria from both flies and litter. The bacteria isolated from flies had very similar resistance characteristics and resistance genes to bacteria found in the poultry litter.

Additional authors of the study include Lance Price, Sean Evans and Thaddeaus Graczyk.
