A bird flu detection in northwest Iowa has put a commercial turkey operation under scrutiny — and prompted Gov. Kim Reynolds to activate emergency resources to help contain the disease.
State and federal agriculture officials confirmed Wednesday that highly pathogenic avian influenza, or H5N1, was detected in a commercial turkey flock in Sac County. The affected operation has approximately 44,000 turkeys and is the largest flock affected by an Iowa bird flu detection so far this year.
The detection marks Iowa’s eighth case of highly pathogenic avian influenza in 2026. Officials have not publicly identified the farm’s exact location within Sac County.
In response, Reynolds issued a disaster proclamation effective immediately through Nov. 27.
The proclamation makes state resources available to help monitor the disease, detect additional infections, contain the virus and carry out disposal and disinfection at affected sites. Agencies that may assist include Iowa Homeland Security and the Iowa Department of Agriculture and Land Stewardship. The proclamation also waives certain regulatory requirements for commercial vehicles responding to affected sites, helping facilitate the response.
The detection comes as wild birds migrate through the region this fall. State agriculture officials warn that wild birds can carry the virus without appearing sick, potentially spreading it to domestic poultry. The disease is often fatal to chickens and turkeys.
The state is urging commercial poultry producers and backyard flock owners to strengthen biosecurity measures to protect their birds.
Warning signs can include a sudden increase in bird deaths, decreased egg production, lethargy, difficulty breathing and trouble walking. Anyone who suspects bird flu in a flock should contact a veterinarian immediately and report the suspected case to the Iowa Department of Agriculture and Land Stewardship at 515-281-5305.
For consumers, officials say the detection does not pose an immediate public health concern, and poultry and eggs remain safe to eat when properly handled and cooked. Poultry and egg products should reach an internal temperature of 165 degrees Fahrenheit.
The Iowa Department of Natural Resources (DNR) is also asking people who find five to 10 or more sick or dead wild birds in a small area to report them to local DNR wildlife management staff.
