OKLAHOMA CITY — The USDA Animal and Plant Health Inspection Service (APHIS) has confirmed a case of Highly Pathogenic Avian Influenza (HPAI) in an Oklahoma dairy herd.

The positive sample was collected by the dairy in April and recently submitted to USDA APHIS for testing. The dairy herd has fully recovered, and the farm has not reported any other cases of HPAI.

There is no concern about the safety of pasteurized milk or dairy products. The commercial milk supply remains safe due to both federal animal health requirements and pasteurization.

Oklahoma is the 13th state to have a confirmed positive case of HPAI in a dairy herd.
