Many public health officials and medical organizations are increasingly concerned about the rising incidence of antibiotic-resistant infections in the United States. According to the Interagency Task Force on Antimicrobial Resistance (co-chaired by the Centers for Disease Control and Prevention (CDC), the U.S. Food and Drug Administration (FDA) and National Institutes of Health), unless antibiotic resistance ―problems are detected as they emerge—and actions are taken quickly to contain them—the world may soon be faced with previously treatable diseases that have again become untreatable, as in the pre-antibiotic era.1
Children, seniors, pregnant women, cancer patients and other vulnerable populations are at greater risk of contracting infections that are becoming less and less responsive to vital antibiotics. Patients in hospitals and residents in nursing-home facilities are particularly susceptible to infection, as they often have weakened immune systems and high exposure to contagions that may originate in health care settings, or in the general community.
One of the key factors contributing to this dramatic increase in antibiotic resistance is the routine, non-therapeutic use of antibiotics in food animal production—not because the animals are sick, but to promote growth and to compensate for the effects of overcrowded and unsanitary conditions. This practice puts human health at risk, because it can breed dangerous strains of bacteria that are antibiotic resistant, and some of them can spread to humans. Last year the FDA, the U.S. Department of Agriculture and the CDC testified before Congress that there was a definitive link between the non-therapeutic uses of antibiotics on industrial farms and the crisis of antibiotic resistance in humans.2
Resistant bacterial infections are harder to treat and require multiple applications of antibiotics, longer hospital stays, and possibly other interventions. Researchers with the Alliance for the Prudent Use of Antibiotics and Cook County Hospital in Chicago estimate the extra costs to the U.S. health care system due to antibiotic-resistant infections range from $16.6 billion to $26 billion per year.3 Health experts recommend that all inappropriate uses of antibiotics be curtailed, including the non-therapeutic use of antibiotics in food animal production, in order to stem the rising tide of resistant infections, and to reduce health care costs.
To help address the public health care crisis of antibiotic resistance, protect patients and communities and lower health care costs, Congress should pass legislation to phase out the use of these life-saving drugs on industrial farms unless animals are sick or directly exposed to disease.
Animal antibiotics are human antibiotics.
Reasons to be concerned about the non-therapeutic use of antibiotics in food animal production:
Animal antibiotics are human antibiotics.
Food-borne illnesses can be antibiotic resistant.
Resistant infections can be deadly.
Pathways to resistant infections are diverse.
