BISMARCK, N.D. — The North Dakota State University Veterinary Diagnostic Laboratory has confirmed the presence of highly pathogenic avian influenza in a non-commercial, backyard flock in Cass County, North Dakota. The detection triggers the suspension of poultry/bird events across the state. If no new cases emerge in 30 days, the suspension will be automatically lifted.
More than 40.57 million domestic and commercial birds have died this year due to avian influenza, according to the U.S. Department of Agriculture's Animal and Plant Health Inspection Service . Neither the new North Dakota case nor a case reported in Minnesota had been added to the USDA database by the afternoon of Aug. 31.
The State Board of Animal Health and the North Dakota Department of Agriculture say they are working closely with USDA-APHIS and local officials in the response. The premises have been quarantined and the flock is being depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system. Owners of domestic birds in a 10 kilometer zone around the affected farm are being instructed to prevent contact between domestic poultry and wild birds and to monitor their flocks closely for illness to prevent the spread of HPAI.
“While we hoped there would not be additional cases this fall, due to the extensive involvement wild birds played in the spread of disease this year, we knew it was possible,” State Veterinarian Dr. Ethan Andress said. “The suspension of poultry/bird events is a precaution to reduce the risk of further spread of avian influenza to North Dakota birds.”
There is no immediate public health concern due to this finding. The risk to people from HPAI is low despite the disease often being fatal for birds.

“As farmers take to the fields this fall, they should avoid contact with sick or deceased wild birds and change out of field clothes or boots when caring for their own poultry,” Agriculture Commissioner Doug Goehring said.
Avian influenza infects many species of wild birds and can be transmitted by direct contact with infected birds or contaminated food or water. Sick and dead wild birds should be reported to North Dakota Game and Fish at https://gf.nd.gov/wildlife/diseases/mortality-report .
