Technical Abstract: Twenty-four epizootics of high pathogenicity avian influenza (HPAI) have occurred in the world since 1959. The largest of these outbreaks has been the H5N1 HPAI which has caused problems in poultry and other birds in 11 Asian countries since 1996. These viruses have also caused severe infections and death in a few humans. Most frequently, the HPAI viruses were transmitted to humans by direct close contact with infected poultry, although a few cases have implicated consumption of raw or uncooked poultry products. The HPAI viruses cause severe systemic infection in multiple poultry species and the viruses can be present in multiple internal organs, meat, eggs and blood. Pasteurization can be effective at inactivation of the viruses in egg products. Cooking at 70C for less than 1 minute will kill HPAI viruses in infected meat.
