A wild duck in Butte County in northern California has tested positive for highly pathogenic avian influenza, adding to a string of unprecedented West Coast bird flu cases. The U.S. Department of Agriculture on Wednesday confirmed that a hunter-shot duck in Butte County was infected with highly pathogenic H5N8. The USDA detected the virus Dec. 31, but didn't make an announcement until Wednesday. The wild duck was found as part of the USDA's increased surveillance on the West Coast and increased outreach to backyard poultry enthusiasts, according to the USDA. Highly pathogenic bird flu had never been detected in California, Oregon and Washington until the past month. Low pathogenic bird flu was found last spring on a quail farm in Stanislaus County in central California. China still restricts all poultry and poultry products from birds slaughtered, processed and shipped from California. Unlike British Columbia, Canada, where some 245,600 birds were culled at 11 poultry farms between Dec. 1-17, highly pathogenic bird flu has not been found in U.S. commercial poultry. The virus in wild birds and backyard flocks in Washington and Oregon has still meant export restrictions for the U.S. poultry industry. "It's possible every additional finding prolongs the situation," USA Poultry and Egg Export Council President Jim Sumner said Wednesday. Some countries, such as South Korea and South Africa, have imposed bans on all U.S. poultry. The USDA says those bans are unwarranted. Many countries have limited their bans to poultry and poultry products from Washington and Oregon. Federal and state officials Tuesday euthanized approximately 500 birds in a backyard flock in Benton County in south-central Washington. The flock had been exposed to highly pathogenic H5N2 bird flu by domestic ducks moved from another flock 9 miles away. The 140 ducks, chickens and turkeys in that flock were euthanized Monday, according to the Washington Department of Agriculture. Also in Whatcom County, Wash., a wild duck and a captive gyrfalcon fed wild duck were infected with highly pathogenic bird flu in December. Also that month, highly pathogenic bird flu broke out among a 100-bird flock of guinea fowl and chickens in Douglas County, Ore. Officials suspect migratory waterfowl along the Pacific Flyway are carrying the disease. Highly pathogenic bird flu cases also have been reported in Asia and Europe within the past two months. No human cases of the viruses have been reported, according to the USDA.
