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 multi-species backyard flock in Dallas County, Iowa. This is Iowa’s 10th detection of H5N1 HPAI within domestic birds in 2025.
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.
The Iowa Department of Agriculture and Land Stewardship is strongly encouraging Iowa poultry producers and backyard flock owners to continue bolstering their biosecurity practices and protocols to protect their flocks. The Department has numerous biosecurity resources to reference on its website.
If poultry producers or those with backyard birds suspect signs of H5N1 HPAI, they should contact their veterinarian immediately. Possible cases must also be reported to the Iowa Department of Agriculture and Land Stewardship at (515) 281-5305.
