There is mounting evidence that the industrial farming of chickens, pigs, and cattle is cultivating more than poultry and livestock — it’s cultivating bacteria that medicine is losing the ability to fight. Antimicrobial drugs, including antibiotics like penicillin, ciprofloxacin, and methicillin, kill pathogenic bacteria. Scientists estimate that 50 percent to 80 percent of all antimicrobials in the United States are not used by doctors to treat sick people or animals but are added to farm animal feed, mostly in such subtherapeutic dosages. Public health researchers like Ellen Silbergeld are convinced that this nontherapeutic use of antimicrobials is building dangerous genetic reservoirs of resistance. If they are right, industrial agriculture is fostering and dispersing drug-resistant bacteria that impair medicine’s ability to protect the public from them.
Kellogg Schwab, director of the Johns Hopkins Center for Water and Health, refers to a typical pig farm manure lagoon that he sampled. “There were 10 million E. coli per liter [of sampled waste]. Ten million. And you have a hundred million liters in some of those pits. So you can have trillions of bacteria present, of which 89 percent are resistant to drugs. That’s a massive amount that in a rain event can contaminate the environment.”
