Good News: Foodborne Diseases on Decline in U.S.

The U.S. Centers for Disease Control reports that infections from foodborne bacteria have fallen since the 1990s, which was attributed to "better food-industry practices." The rates of infection from most bacteria responsible for food contamination -- E. coli, campylobacter, cryptosporidium and yersinia -- dropped between 31 and 45 percent. Salmonella infections dropped the least, only eight percent, "mainly because health officials still know little about the bacteria, the CDC said."
