The Iowa Department of Agriculture has confirmed two more cases of Avian Influenza in the state.

The latest cases are in a commercial turkey flock in Pocahontas County and the other is in a mixed species backyard flock in Guthrie County. They are the second and third cases of the bird flu confirmed in Iowa in the past three days. The first was a Buena Vista County commercial turkey flock that was announced Friday.

It’s believed the bird flu is carried by migrating birds. There were two other bird flu cases in Iowa in January and March of this year.
