National Animal Health Reporting System

Overview
The U.S. Department of Agriculture’s (USDA) National Animal Health Reporting System (NAHRS) is a comprehensive reporting system for World Organization for Animal Health (OIE)-reportable diseases in the United States. Under NAHRS, participating state animal-health officials report monthly on the occurrence of confirmed OIE-reportable diseases in U.S. livestock, poultry, and aquaculture species. States receive a monthly report from this system.
