Highly Pathogenic Avian Influenza Detected in a Sioux County Dairy

Jun 12, 2024

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 (HPAI) in a herd of dairy cattle in Sioux County, Iowa. 

About HPAI 
HPAI is a viral disease that affects both wild and domestic bird populations as well as lactating dairy cattle. HPAI can travel in wild birds without those birds appearing sick, but is often fatal to domestic bird populations, including chickens and turkeys. With supportive care, dairy cattle recover with little to 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. The Iowa Department of Agriculture and Land Stewardship has biosecurity recommendations for dairy herds to utilize. In addition, the Department has numerous other biosecurity resources for poultry producers and livestock farms to reference on its website. Farmers or farm workers who interact regularly with both dairy and poultry or who interact frequently with other farm workers in poultry or dairy, should take extra precautions to limit possible transmissions. 

Suspected Cases in Dairy 
If dairy producers suspect cases of HPAI, they should contact their herd veterinarian immediately. Possible cases must also be reported to the Iowa Department of Agriculture and Land Stewardship at (515) 281-5305. 
Clinical signs of HPAI in dairy may include: 
•    Decrease in food consumption with a simultaneous decrease in rumination 
•    Clear nasal discharge 
•    Drop in milk production 
•    Tacky or loose feces 
•    Lethargy 
•    Dehydration 
•    Fever 
•    Thicker, concentrated, colostrum-like milk
