Seattle: U.S. officials say they've found avian influenza in wild birds in Washington state but there's no immediate public health concern.
The Department of Agriculture said on Tuesday that separate strains of the H5 virus have been confirmed in northern pintail ducks and gyrfalcons that were fed wild birds killed by hunters.
The agency says both viruses have been found in other parts of the world and have not caused any human infection to date.
Neither virus has been found in commercial poultry in the U.S.
An avian influenza outbreak this month in southwest British Columbia has spread to seven poultry farms, and 155,000 birds have died of the virus or will be euthanized.
In Washington state, the virus was detected in Whatcom County, which is on the Canadian border.
