Government agriculture officials will kill up to 5,000 ducks, geese, chickens, pheasants and turkeys due to a bird flu outbreak at a hunting operation Washington's Okanogan county.
About 40 birds at a game farm in Riverside, Washington, were ill over the weekend and tested positive for bird flu. The U.S. Department of Agriculture and the state of Washington announced it would kill birds from the flock and establish a quarantine around it.
The birds are used for private hunting excursions and retriever training. The flock represents the largest number of birds the state has had to test and possibly kill during 2015 bird flu outbreaks.
Washington state has now lifted a quarantine in the Tri-Cities but one in Port Angeles remains. No new cases have been found in either location.
An outbreak in California led to 146,000 turkeys being killed at a commercial operation. Several countries including China have banned poultry and eggs from the United States.
