It is egg hunting season in many rural Alaska communities, and harvesters want to know if they should be concerned about eating eggs from wild birds. According to guidance from the State of Alaska and USFWS, the risk from avian flu for people is very low.

Cases are being detected all over the state, from the Aleutians to Mat-Su to Haines and the Interior.“What we’re seeing this year is an unprecedented level of highly pathogenic avian influenza in wild birds,” said Andy Ramey of USGS.

The advice to hunters, don’t shoot or harvest game that appears sick. If you found an animal injured or dead, just leave it there. When processing, wear rubber gloves and washing the area the game was cleaned on. You should also cook game to an internal temperature of at least 165°F.

While the risk to human health is low, Gerlach has said that avian influenza could pose a threat to not only the state’s domestic birds but also wild birds, including geese, shore birds, vultures and eagles. There’s no treatment for birds that are infected, and the mortality rate for poultry and raptors like hawks, eagles or owls is especially high. Possible signs of infection includes the “sudden death of multiple birds in the flock, nasal discharge, sneezing, and coughing, or respiratory distress."
