Iowa has another five probable cases of highly pathogenic avian influenza (HPAI) on the table in commercial poultry farms in Osceola, O'Brien, and Sioux Counties in northwest Iowa, says Bill Northey, the Iowa Secretary of Agriculture. 

Iowa confirmed its first case of the H5N2 strain of HPAI two weeks ago on a turkey farm. A week later a layer farm housing 3.8 million birds confirmed the virus, which was the largest contamination to date. 

Today, Northey announced the five probable cases that were quarantined over the weekend and are awaiting confirmation of HPAI.
