Antibiotics in Food Animals: FAQ (cont.)
Such "production use" of antibiotics is what the FDA, in its June 2010 guidance to the industry, deemed unwise or "injudicious."
How can antibiotics given to animals create drug-resistant germs?
If you get an antibiotic prescription from your doctor, you'll be warned to take every single one of the pills exactly as prescribed. That's because the last few pills mop up the most drug-resistant germs. If you take too low a dose, the most resistant germs remain.
The same thing happens in animals. Veterinarians treat sick animals with appropriate doses of antibiotics.
But when antibiotics are used to make animals grow faster, they are given at low doses over long periods of time. That's a recipe for growing drug resistant bacteria in food animals.
Can drug-resistant bacteria in food animals find their way to humans?
There are some researchers, such as an expert panel of the Institute of Food Technologists, who say the odds are low that any of these bugs will find their way into humans. But in testimony before Congress, the USDA, the FDA, and the CDC all said that the use of antibiotics in food animals leads to infections with drug resistant bacteria to humans.
And in a letter to Congress, 14 health groups -- including the American Medical Association and the American Academy of Pediatrics -- said "overuse and misuse of important antibiotics in food animals must end, in order to protect human health."
The World Health Organization has also warned that overuse of antibiotics in food animals can lead to drug-resistant infections in people.
Didn't the FDA ban use of one antibiotic in food animals?
In January 2012, the FDA banned certain uses of cephalosporin antibiotics in food animals effective April 5, 2012.
The ruling prohibits giving food animals the kinds of cephalosporins used to treat disease in humans or in pets. Exceptions allow off-label use by veterinarians to treat specific diseases, and allow the use of an older cephalosporin called cephapirin, which is not used in humans.
Cephalosporins are not one of the antibiotics used to increase animal growth.
In 2010, U.S. meat and poultry producers used 27 tons of cephalosporins. That sounds like a lot. But it's only a fraction of the 14,600 tons of antibiotics used in food animals that year.
One consumer group called the FDA action a step forward -- but only a baby step.
Will the FDA ban use of other antibiotics in food animals?
There is no indication that the FDA plans to ban food-animal use of other antibiotics already approved for such uses.
