MINNESOTA, US - USDA has confirmed an outbreak of highly pathogenic avian influenza of the H5N2 subtype in a commercial turkey flock in Minnesota.
The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza in a commercial turkey flock in Pope County, Minnesota.
This is the first finding in the Mississippi flyway. It 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.
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. The United States has the strongest AI 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 OIE and international trading partners of this finding. USDA also continues to communicate with trading partners to encourage adherence to OIE standards and minimise 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.
These virus strains can travel in wild birds without them appearing sick. People should avoid contact with sick/dead poultry or wildlife. If contact occurs, wash your hands with soap and water and change clothing before having any contact with healthy domestic poultry and birds.
All bird owners, whether commercial producers or backyard enthusiasts, should continue to practice good biosecurity, prevent contact between their birds and wild birds, and to report sick birds or unusual bird deaths to State/Federal officials, either through your state veterinarian or through USDA’s toll-free number at 1-866-536-7593. Additional information on biosecurity for backyard flocks can be found at healthybirds.aphis.usda.gov.
