For Bob, a crucial step came when he switched to organic production eight years ago. A Stanford study has cast doubt on whether organic food is more nutritious, but it affirms that organic food does contain fewer pesticides and antibiotic-resistant bacteria. Bob’s big worry in switching to organic production was whether cows would stay healthy without routine use of antibiotics because pharmaceutical salesmen were always pushing them as essential. Indeed, about 80 percent of antibiotics in the United States go to farm animals — leading to the risk of more antibiotic-resistant microbes, which already cause infections that kill some 100,000 Americans annually.
