Surveillance and Data Systems
CDC uses several surveillance systems to track foodborne, waterborne, and animal contact diseases reported in the United States. Most often, information in these systems comes from state and local health agencies. Although some of these systems have been used extensively for decades, new surveillance methods have improved the quality, quantity, and timeliness of their data. The surveillance systems described below play an important role in detecting and preventing disease and outbreaks.
Foodborne Disease Surveillance
National Antimicrobial Resistance Monitoring System for Enteric Bacteria (NARMS)
NARMS is an interagency public health surveillance system that tracks antimicrobial resistance in foodborne and other enteric (intestinal) bacteria from humans (CDC), retail meats (FDA), and food animals (USDA) in the United States.
PulseNet is a national laboratory network that connects foodborne illness cases to detect outbreaks. PulseNet uses DNA fingerprinting of bacteria making people sick to detect thousands of local and multistate outbreaks.
CDC is creating an interactive dashboard to present foodborne surveillance data, including real-time data from PulseNet isolates. As an interim step, we will provide interim quarterly static reports of PulseNet data.
System for Enteric Disease Response, Investigation, and Coordination (SEDRIC)
CDC, state and local health departments, the U.S. Food and Drug Administration, and the U.S. Department of Agriculture Food Safety and Inspection Service use SEDRIC, a secure, web-based platform that combines epidemiologic, laboratory, and traceback data in real time, to collaborate when investigating multistate outbreaks.
Animal Contact Outbreak Surveillance
Waterborne Disease Surveillance
National Outbreak Reporting System
National Outbreak Reporting System (NORS)
NORS is a web-based platform that U.S. health departments use to report outbreak information to CDC. Through NORS, CDC collects reports of enteric disease outbreaks caused by bacterial, viral, parasitic, chemical, toxin, and unknown germs. NORS also collects reports of foodborne and waterborne disease outbreaks that are not enteric. NORS is managed by the National Center for Immunization and Respiratory Diseases.
