HAMILTON COUNTY, Iowa (IOWA CAPITAL DISPATCH) – A case of highly pathogenic avian influenza has been detected in a commercial turkey flock of about 18,000 birds in Hamilton County, according to the Iowa Department of Agriculture and Land Stewardship. Iowa has had nine detections of the H5N1 strain of the highly pathogenic avian influenza, which has impacted more than 184 million commercial and backyard birds since February 2022.

IDALS reported a case of the bird flu in a Calhoun County turkey flock in October. The October case was the first detection in the state since April. Gov. Kim Reynolds issued a disaster proclamation for Hamilton County following the HPAI detection. The proclamation makes state resources more available as officials work to dispose of birds exposed to the virus and monitor, contain and further detect the bird flu.

IDALS asked producers to exercise heightened biosecurity around their flocks to help prevent the spread of HPAI, which is usually deadly for exposed poultry. Producers who notice sudden deaths in a flock, lethargy, decreased egg production, or birds with swollen heads and difficulty breathing, should contact their veterinarians, according to the agriculture department.

Turkey, chicken and egg products remain safe to consume during the current HPAI outbreak, IDALS said.
