Highly Pathogenic Avian Influenza Detected in a Mixed Species Flock in Kossuth County
DES MOINES, Iowa (Jan. 22, 2026) – 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 mixed species flock in Kossuth County, Iowa. The flock includes game bird pheasants and backyard chickens. This is Iowa’s first detection of H5N1 HPAI within domestic birds in 2026.
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 continue bolstering their biosecurity practices and protocols to protect their flocks. The Department has numerous biosecurity resources to reference on its website.
Suspected Cases in Poultry
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.
Clinical signs of H5N1 HPAI in birds may include:
It remains safe to enjoy eggs and poultry products. As a reminder, consumers should always properly handle and cook eggs and poultry products, including cooking to an internal temperature of 165˚F.
Wild and Migratory Birds
The Iowa Department of Natural Resources (DNR) asks those who find 20 or more sick or dead wild birds in a small area to report their findings to local DNR Wildlife Management staff.
Public Health
The Centers for Disease Control (CDC) continues to believe the threat to the general public remains low. Any questions related to public health should be directed to the Iowa Department of Health and Human Services.
List of Confirmed Cases
As H5N1 HPAI detections are confirmed by the National Veterinary Services Laboratory (NVSL) in Ames, those cases are added to tracking websites located on the USDA APHIS website.
