Stevens County Goat Tests Positive for Same Influenza Virus Affecting Poultry
A Stevens County goat kid (juvenile goat) residing on a farm with a Highly Pathogenic Avian Influenza (HPAI) positive poultry flock tested positive for the same virus. This is the first U.S. detection of HPAI in a domestic ruminant (cattle, sheep, goats, and their relatives). All poultry on the property were already quarantined from the February HPAI detection. Following the confirmation of HPAI in the goat, the Board quarantined all other species on the premises. The Board is working with the U.S. Department of Agriculture (USDA) to investigate the transmission of the virus in this case.
“This finding is significant because, while the spring migration is definitely a higher risk transmission period for poultry, it highlights the possibility of the virus infecting other animals on farms with multiple species,” said State Veterinarian, Dr. Brian Hoefs. “Thankfully, research to-date has shown mammals appear to be dead-end hosts, which means they’re unlikely to spread HPAI further.”
Earlier this month the owner notified the Board of unusual deaths of newly kidded goats on the property where a backyard poultry flock was depopulated due to HPAI in February. The goats and poultry had access to the same space, including a shared water source. One of the goat carcasses was taken to the University of Minnesota Veterinary Diagnostic Laboratory (VDL), where it tested positive for influenza A. The National Veterinary Services Laboratories (NVSL) later confirmed H5N1 HPAI, which is the same virus circulating in the national outbreak that began in 2022. Samples from the adult goats were negative for HPAI and all appear healthy; no more sick goat kids have been reported since March 11.
