Highly Pathogenic Avian Influenza Detected in a Commercial Turkey Flock in Sac County
DES MOINES, Iowa (Feb. 19, 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 Sac County, Iowa. This is Iowa’s fourth detection of H5N1 HPAI within domestic birds in 2025.
About H5N1 HPAI
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. H5N1 HPAI can also impact dairy cattle, and 13 cases were detected in Iowa dairy herds in June of 2024. With supportive care, dairy herds recover with limited, or no mortality associated with the disease.
Heightened Biosecurity
The Iowa Department of Agriculture and Land Stewardship is strongly encouraging Iowa poultry producers and dairy farmers to bolster their biosecurity practices and protocols to protect their flocks and herds. In addition, the Department has numerous biosecurity resources for poultry producers and dairy and livestock farmers 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:
