The Animal and Plant Health Inspection Service (APHIS) confirmed this week that the first commercial case of highly pathogenic avian influenza (HPAI) was discovered in South Dakota. APHIS says the virus was confirmed in a commercial turkey flock of 47,300 birds on October 4.
Another case was also recently confirmed in a small non-commercial flock located in Idaho. The Canadian Food Inspection Agency also reported four commercial cases of the virus since mid-September. The most recent case was announced on October 3 in a commercial flock located in Alberta. The agency doesn’t disclose the type of poultry or how many birds were involved in the infection.
One of the first clinical signs of HPAI in domestic birds is sudden, unexplainable death. Many infected birds drop their water consumption in the 72 hours that lead up to their unexplainable death. Decreased egg production and depression in layers may be another sign that the birds are ill.
