The National Antimicrobial Resistance Monitoring System for Enteric Bacteria (NARMS) was established in 1996 and is a collaboration among state and local public health departments, CDC, FDA and the USDA.

The surveillance system tracks changes in the antimicrobial susceptibility of four pathogens transmitted commonly through food—Campylobacter, E. coli O157, Salmonella, and Shigella. It covers people reporting illness; retail meats and food animals in the United States.
