Document Summary
The us model of high-density agriculture where livestock are kept in very close quarters is an ideal breeding ground for bacteria. Scientists predicted in 2001 in the us: 3 million pounds in human medicine, 24. 6 million pounds in animal agriculture, 70% of the total are used for non-therapeutic uses (ie not treating a sick animal) Potential transmission routes from animals to humans: ventilation of facilities with particles in the air, direct contact with livestock, contaminated soil, drinking water, eating contaminate meat or crop fertilized with contaminated animal waste. Some evidence that use of antibiotic in animals may increase bacterial resistance in humans. After a drug began being used in livestock, saw great increase of antibiotic resistant bacteria in human fecal samples. Frequency of antimicrobial resistance study saw that the poultry works vs the population had significantly more frequency of resistant cases.
