Health Care and the Antibiotic Resistance Crisis

Health Care and the Antibiotic Resistance Crisis

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.

Reasons to be concerned about the non-therapeutic use of antibiotics in food animal production:

Animal antibiotics are human antibiotics.

  • Many of the antibiotics used in food animal production—for example, penicillins, tetracyclines, macrolides and sulfonamides—are identical to, or from the same family as, drugs used in human medicine to cure serious diseases. According to the CDC, because these classes of antibiotics are similar, bacteria resistant to antibiotics used in animals also will be resistant to antibiotics used in humans.4 The FDA reported that more than 20.5 million pounds of antibiotics were sold for use in U.S. food animal production in 2009, including for non-therapeutic purposes.5
  • As the use of antibiotics has increased, there has been a growth in the number of antibiotic-resistant bacterial strains against which common antibiotics are no longer effective.

Food-borne illnesses can be antibiotic resistant.

  • According to the FDA, 5,000 deaths, 325,000 hospitalizations, and 76 million cases of food-borne illness occur annually in the U.S.6
  • Many of these antibiotic-resistant strains of bacteria include those that cause common food-borne illness. These bacteria include, but are not limited to, Escherichia coli 0157:H7, Salmonella, Listeria monocytogenes, Cyclospora cayetanesis and Campylobacter jejuni.
  • Food-borne illnesses are now becoming more difficult to treat due to the increase in antibiotic-resistant strains and the decreased effectiveness of antibiotics routinely used as a first-line defense.

Resistant infections can be deadly.

  • According to the Infectious Diseases Society of America, 90,000 people die each year of a hospital-acquired infectious disease. Many of these infections are resistant to at least one antibiotic.7
  • Other antibiotic-resistant infections are causing a strain on the health care industry as well. MRSA, or Methicillin-resistant Staphylococcus aureus, a multi-drug resistant skin infection that can infiltrate the blood system and infect the lungs and urinary tract, causes more than 60 percent of Staph infections in U.S. hospitals.8 MRSA is now showing up in people outside of the health care setting. The CDC reports that in 2007, 14 percent of people with MRSA infections had acquired them from the general community.9
  • Clostridium difficile is another bacterial infection posing a challenge to doctors and hospitals. C. diff. causes symptoms ranging from diarrhea to life-threatening inflammation of the colon and sepsis, and often strikes after patients have been on antibiotic treatment. The Mayo Clinic says that in recent years, C. diff. infections have become more frequent, more severe and more difficult to treat. Each year, tens of thousands of people in the U.S. fall ill, including healthy people who are not hospitalized or taking antibiotics.10

Pathways to resistant infections are diverse.

  • If bacteria become resistant to antibiotics, they can spread in many ways, including handling or eating contaminated meat or produce fertilized by contaminated manure or coming in contact with farm or food workers who handle contaminated animals or meat or with soil and water fouled by animal waste. 11, 12, 13, 14, 15
