Cattle Diets Could Control E Coli Danger
Simple change in cattle diets in the days before slaughter may reduce the risk of Escherichia coli (E. coli) infections in humans, U.S. Department of Agriculture (USDA) and Cornell University microbiologists have discovered. Grain-based cattle diets promote the growth of E. coli that can survive the acidity of the human stomach and cause intestinal illness. By feeding hay to cattle for about five days before slaughter, the number of acid-resistant E. coli can be dramatically reduced.
