Avian Influenza Found in Oregon Duck
A Eurasian H5 strain of avian influenza was recently found in a mallard duck harvested by a hunter in Morrow County, Oregon, in the north-central part of the state along the Washington border. According to the U.S. Department of Agriculture’s Animal and Plant Inspection Service (APHIS), testing wasn’t able to determine the exact strain or whether the virus was low- or high-pathogenic.
No highly pathogenic avian influenza (HPAI) has been found in any commercial or backyard poultry since June 17, 2015, APHIS says. On November 18, USDA reported to the World Organization for Animal Health (OIE) that all cases of HPAI in commercial poultry in the U.S. had been resolved, and declared the U.S. free of HPAI.
When the H5N2 poultry outbreak died down last summer, APHIS warned it could reappear in the fall as birds began to migrate, and has so far tested 24,000 samples collected from hunter-harvested birds and wild birds found dead since July 1, 2015, with a goal of 40,000 samples tested by that date in 2016.
APHIS encourages poultry producers of all sizes to perform a biosecurity self-assessment and asks that sick birds or unusual bird deaths be reported by calling 866/536-7593.
