The Iowa Department of Agriculture and Land Stewardship has recently identified the first case of highly pathogenic avian influenza (HPAI) in 2025 within a diverse backyard flock located in Clinton County. This incident follows a series of detections in both commercial and non-commercial flocks across the state since December 2024. Concurrently, the Department of Natural Resources reported an increase in H5N1 bird flu cases among wild birds during the same period. Despite these developments, health authorities maintain that poultry products remain safe for consumption, and the overall public health risk remains low.

In December, Iowa recorded its first human infection of the virus, which resulted in mild symptoms but no further cases have been detected among humans in the state. Meanwhile, Louisiana experienced its first severe human infection leading to fatality. The patient had underlying health conditions and was over 65 years old. To mitigate risks, Governor Kim Reynolds extended disaster proclamations in several counties affected by commercial flock outbreaks, emphasizing stringent biosecurity protocols for both commercial and backyard producers.

Enhanced Vigilance for Commercial and Backyard Flocks

With the resurgence of avian influenza, the agricultural sector is on high alert. Authorities urge immediate veterinary consultation if there are suspicions of HPAI in birds. Producers are advised to implement enhanced biosecurity measures to prevent the spread of the virus. These measures include wearing protective equipment and avoiding contact with sick or deceased animals. Proper containment and depopulation procedures are critical to controlling outbreaks in affected areas.

Commercial and backyard flock owners must remain vigilant against potential signs of infection. Early detection and prompt action can significantly reduce the impact of HPAI. By adhering to strict biosecurity guidelines, such as limiting access to facilities, disinfecting equipment, and monitoring bird health closely, producers can safeguard their flocks and minimize economic losses. Communication between farmers and veterinarians is essential for timely intervention and effective management of any suspected cases.

Public Health and Wildlife Monitoring

While the risk to public health from avian influenza remains minimal, individuals with direct exposure to infected birds should be cautious. Those experiencing flu-like symptoms or eye infections after contact with potentially affected animals should seek medical advice immediately. Public health officials emphasize the importance of preventive measures, including proper hygiene and the use of personal protective equipment when handling birds.

Iowans are encouraged to report clusters of five or more sick or dead wild birds to local wildlife biologists within a week. Such vigilance helps authorities track the virus's spread in wild populations, facilitating swift response strategies. Collaboration between public health agencies, wildlife experts, and the community is crucial for managing this outbreak effectively. Authorities stress that maintaining awareness and following recommended precautions will help protect both human and animal health.
