The infected herd is in Stark County
Officials in North Dakota are reminding livestock producers about the dangers of anthrax after the North Dakota State University Veterinary Diagnostic Lab confirmed its presence in a herd in Stark County.
North Dakota Agriculture anthrax maps dating back to 2005 show this is Stark County’s first case of anthrax since that time.
That year, more than 1,000 head died from anthrax.
With this case in 2025, which appears to be the first confirmed in the U.S. this year, farmers should be vigilant and review anthrax plans, State Veterinarian Dr. Ethan Andress said.
“Producers in past known affected areas and counties should consult with their veterinarians to review their risk factors and vaccination needs,” he said in a statement. “If producers have unusual losses on pasture, they should reach out to their local veterinarian as they are experienced and trained for this type of response.”
The bacteria Bacillus anthracis causes anthrax.
These bacteria can survive in soil as spores for decades.
The spores are brought to the surface when the ground is disturbed by erosion, heavy rain or other factors.
Livestock can become infected by breathing in, eating or drinking the spores.
One challenge with anthrax is how quickly it can spread through an animal’s system.
Animals can die within hours of ingesting spores without showing any symptoms.
Some symptoms, however, can include trembling, high temperature, difficulty breathing and convulsions.
Farmers have options when it comes to protection.
Vaccines are available, but it could take more than a week to establish herd immunity.
