About NAHRS

The National Animal Health Reporting System (NAHRS) is a joint effort of the United States Animal Health Association (USAHA), American Association of Veterinary Laboratory Diagnosticians (AAVLD), and USDA-APHIS. NAHRS is designed to collect data from chief State animal health officials on the presence of confirmed World Organization for Animal Health (OIE) -reportable diseases in specific livestock, poultry, and aquaculture species in the United States. It is a key component of the National Animal Health Surveillance System, and it is the only comprehensive reporting system for OIE-reportable diseases in the United States. NAHRS functions under the direction of the NAHRS Steering Committee and is managed by the USDA-APHIS-VS-Centers for Epidemiology and Animal Health (CEAH) National Surveillance Unit (NSU).

By providing timely summary-level information on animal health status to our trading partners, NAHRS helps protect the U.S. share of the global market for animals and animal products. U.S. animal health status information obtained through NAHRS helps the United States meet trade commitments, reduce disruption of existing trade, and aid in expanding trade. Individual States benefit from participating in NAHRS by strengthening their internal animal health surveillance abilities and enabling animal industries to provide information needed to develop and maintain international trade.
