The U.S. Department of Agriculture’s Animal & Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic avian influenza (HPAI) strain H5N2 in a commercial turkey flock in Pope County, in Minnesota's west-central region.
APHIS noted that this is the first finding in the Mississippi flyway and is the same strain of avian influenza that has been confirmed in backyard and wild birds in Washington, Oregon and Idaho as part of the ongoing incident in the Pacific flyway.
Samples from the turkey breeder replacement flock, which experienced increased mortality, were tested at the University of Minnesota Veterinary Diagnostic Laboratory, and the APHIS National Veterinary Services Laboratories in Ames, Iowa, confirmed the finding. APHIS is partnering closely with the Minnesota Board of Animal Health on a joint incident response. State officials quarantined the affected premises and the remaining birds on the property will be depopulated to prevent the spread of the disease. Birds from the involved flock will not enter the food system.
APHIS explained that the Centers for Disease Control & Prevention (CDC) considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry to be low. No human infections with these viruses have been detected at this time. The Minnesota Department of Health is working directly with poultry workers at the affected facility to ensure they are taking the proper precautions. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165°F kills bacteria and viruses.
Federal and state partners are working jointly on additional surveillance and testing in the nearby area, following existing avian influenza response plans. APHIS said the U.S. has the strongest avian influenza surveillance program in the world, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets, and in migratory wild bird populations.
USDA will be informing the World Organization for Animal Health (OIE) and international trading partners of this finding. USDA also continues to communicate with trading partners to encourage adherence to OIE standards and minimize trade impacts. OIE trade guidelines call on countries to base trade restrictions on sound science and, whenever possible, limit restrictions to those animals and animal products within a defined region that pose a risk of spreading disease of concern.
