Iowa agriculture officials said Monday that another commercial egg farm in the state has been infected with bird flu, the first commercial farm case identified since April, when a turkey farm was infected.
The latest case is in Wright County in north central Iowa about 80 miles (130 kilometers) north of Des Moines housing about 1.1 million chickens.
Iowa has had 15 commercial farms infected this year, including turkeys, egg-laying hens and other chickens. In addition, five backyard flocks have been infected. Because the virus is highly contagious, all birds on an infected farm are killed and disposed of to avoid the spread of the disease.
