DES MOINES, Iowa (AP) — A bird-flu strain that has already hit numerous turkey farms in the Midwest has been found in a turkey flock in northwest Iowa. An Iowa Department of Agriculture spokesman says Tuesday the H5N2 strain of bird flu virus has been confirmed in a barn on a farm housing 27,000 birds in Buena Vista County. The disease was suspected when turkeys began dying in the barn.

An Iowa Poultry Association spokesman says the farm is under quarantine and the turkeys will be euthanized. Animal health officials have long said the virus is dangerous to all commercial poultry. Iowa has 130 turkey farms raising 11 million turkeys a year. The state also is the nation’s leading egg producer with 59.6 million egg layers. No chicken flocks in Iowa have been infected.
