The CDC estimates that more than 400,000 U.S. residents become ill with infections caused by antibiotic-resistant foodborne bacteria every year. Antibiotic use in food animals can lead to resistant infections in humans. Studies have shown that:
- Antibiotic use in food animals allows antibiotic-resistant bacteria to grow and crowd out the bacteria that do not respond to antibiotics;
- Resistant bacteria can contaminate food from the animals;
- Resistant bacteria in food can cause infections in humans; and
- These bacteria also can get into the environment through animal stool and may spread to produce that is irrigated with contaminated water.
