The National Antimicrobial Resistance Monitoring System (NARMS) is a U.S. public health monitoring system that tracks antimicrobial resistance (AMR) in foodborne and other intestinal bacteria using a One Health approach. As outlined in the NARMS Strategic Plan: 2021-2025, the overall purpose of NARMS is to:
- Monitor trends in antimicrobial resistance among enteric bacteria from humans, retail meats, and animals at the time of slaughter;
- Disseminate timely information on antimicrobial resistance in pathogenic and commensal microorganisms to stakeholders in the U.S. and abroad to promote interventions that reduce resistance among foodborne bacteria;
- Conduct research to better understand the emergence, persistence, and spread of antimicrobial resistance;
- Provide timely antimicrobial resistance data for outbreak investigations; and
- Provide data that assist the FDA in making decisions related to the approval of safe and effective antimicrobial drugs for animals.
NARMS gathers surveillance data from human clinical samples, animal slaughter samples and retail meat samples. This approach to integrated surveillance provides information needed to assess the nature and magnitude of resistance in bacteria moving through the food supply and causing illnesses in humans. The NARMS interactive data dashboards found below allow the user to explore data in different ways.
