Iowa Confirms Tenth H5N1 Case

By Andi Anderson

State and federal agriculture officials have confirmed a new case of Highly Pathogenic Avian Influenza, commonly known as bird flu, in a backyard poultry flock in Dallas County, Iowa. This marks Iowa’s tenth confirmed case of H5N1 in domestic birds in 2025.

H5N1 bird flu is a viral disease that affects both wild and domestic birds. Wild birds can carry the virus without appearing sick. However, the disease is often fatal for domestic birds such as chickens and turkeys. Because of this risk, authorities are encouraging all poultry owners to stay alert and protect their flocks.

Agriculture officials are strongly advising poultry producers and backyard flock owners to improve their biosecurity practices. This includes limiting visitors to bird areas, keeping equipment clean, and preventing contact between domestic birds and wild birds. Strong biosecurity helps reduce the chance of the virus spreading to healthy flocks.

Bird owners should carefully watch their birds for signs of illness. Common warning signs include sudden bird deaths, loss of appetite, reduced egg production, soft or misshapen eggs, swelling of the head or face, blue or purple coloring of combs and legs, breathing problems, coughing, sneezing, diarrhea, and trouble walking. Anyone who notices these signs should contact a veterinarian right away and report the case to state agriculture officials.

Food safety remains an important focus. Officials confirm that eggs and poultry products are safe to eat when handled and cooked properly. Consumers are reminded to cook poultry and eggs to an internal temperature of 165 degrees Fahrenheit to ensure safety.

People who find large numbers of sick or dead wild birds in one area are encouraged to report their findings to wildlife officials. Public health experts continue to state that the risk to the general public remains low.

Confirmed cases are recorded by national veterinary laboratories and added to official tracking systems. These efforts help monitor the disease and protect poultry farms across the state.
