The feeding of animals like chickens, and almost every other meat animal, uses routine doses of antibiotics on almost every day of their lives. Drug-resistant infections are responsible for at least 700,000 deaths around the world each year. Disease organisms have been developing defenses against the antibiotics meant to kill them for as long as antibiotics have existed.
Tetracycline arrived in 1948 and resistance was beginning before the 1950s ended. Erythromycin came in 1952 and resistance arrived in 1955. Methicillin was developed in 1960 specifically to counter penicillin resistance, yet within a year, staph bacteria developed defenses against it as well (MRSA). Each time pharmaceutical chemistry produced new antibiotics the bacteria adapted faster and faster.
There has been over-prescription of antibiotics for humans, but the main abuse is that 80% of the antibiotics in the U.S. and 50% around world are used in animals. Abuse of antibiotics is another grave threat our world is facing that we are not addressing with enough seriousness. Without changes to our food system, that which was constructed to nourish us may ultimately destroy us.
