Highly Pathogenic Avian Influenza Detected in a Commercial Turkey Flock in Calhoun County

Oct 03, 2025

The Iowa Department of Agriculture and Land Stewardship and the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) have detected a case of Highly Pathogenic Avian Influenza (H5N1 HPAI) in a commercial turkey flock in Calhoun County, Iowa. This is Iowa’s eighth detection of H5N1 HPAI within domestic birds in 2025.

About H5N1 HPAI in Birds

H5N1 HPAI is a viral disease that affects both wild and domestic bird populations. H5N1 HPAI can travel in wild birds without those birds appearing sick, but is often fatal to domestic bird populations, including chickens and turkeys.

Heightened Biosecurity

The Iowa Department of Agriculture and Land Stewardship is strongly encouraging Iowa poultry producers and backyard flock owners to bolster their biosecurity practices and protocols to protect their flocks. The Department has numerous biosecurity resources to reference on its website.
