Antibiotics are essential to the so-called "miracle" of modern medicine. Now antibiotic-resistant bacteria have shown up at American grocery stores. Researchers in Arizona sampled meat and poultry sold at grocery stores in Flagstaff, Los Angeles, Chicago, Fort Lauderdale and Washington, DC. What they found has added fuel to the controversy over the use of antibiotics on factory farms. Some claim that's evidence that antibiotics are losing their effectiveness because of overuse on American farms.
