The Food borne Diseases Active Surveillance Network (FoodNet) is the principal food borne disease component in the Emerging Infections Program of the Centers for Disease Control and Prevention (CDC). Selected state health departments, the U.S. Department of Agriculture Food Safety Inspection Service, and the U.S. Food and Drug Administration collaborate with CDC on FoodNet.

FoodNet began in 1996 with five sites. Since then, it has expanded to 10 sites (called "catchment areas")-seven states (Connecticut, Georgia, Maryland, Minnesota, New Mexico, Oregon, and Tennessee) and selected counties in three other states (California, Colorado, and New York). These sites cover 44.5 million people or 15% of the U.S. population.
