Background Information - Avian Influenza Testing in Meat-Type Chickens
USDA's Animal and Plant Health Inspection Service (APHIS) Veterinary Services (VS) works closely with State and commercial industry on programs to monitor and test domestic poultry and wild birds to detect the occurrence of avian influenza (AI). One of these industry partners is the National Chicken Council (NCC), which represents the U.S. broiler industry and conducts rigorous testing for AI. The NCC Avian Influenza Monitoring Plan focuses on extensive private laboratory testing in which every participating company tests all broiler flocks before slaughter; this exceeds the minimum national standards established by USDA for AI surveillance. NCC participating companies represent 98% of the U.S. broiler production.
USDA APHIS Veterinary Services collaborates with the NCC to maintain secure data reporting systems that allow NCC testing data to be used in national avian influenza surveillance. The surveillance information provided on these Web pages regarding avian influenza testing in meat-type chickens results from the collaborative efforts of NCC industry partners and USDA to assure that the commercial poultry industry is providing a safe food supply. This information also demonstrates to international partners that U.S. avian influenza surveillance assures the safety of poultry exports to other countries.Questions about these data should be referred to the National Surveillance Unit (national.surveillance.unit@aphis.usda.gov).
