The Iowa Department of Agriculture said Friday it has confirmed an outbreak of avian influenza in a commercial egg-laying operation in Taylor County, a southwestern county located on the Missouri border.
The state said nearly 920,000 laying hens would be destroyed to prevent the spread of the disease that’s highly contagious to other birds.
Iowa has experienced two other outbreaks of the virus as it also spreads in other states across the U.S. Officials confirmed the first outbreak March 1, when a backyard flock of 42 chickens and ducks tested positive for highly pathogenic avian influenza; and on Sunday, when 50,000 turkeys in a commercial facility in Buena Vista County tested positive for the virus.
