Answer to Question 1

Antibiotics are administered in animal feed to help reduce the risk of infection in large herds that are crowded together and to promote faster growth and greater meat production. The concern is that similar antibiotics are used to treat infections in people. Bacteria grow quickly and can mutate into strains resistant to the killing effects of the antibiotic drugs. If an E. coli bacterium becomes resistant to a particular antibiotic, the bacterium will continue to grow even if the drug is present. If this bacterium enters a person and causes an infection, the drugs used to treat the infection may not work because the bacterium is resistant to the drugs.
