North Dakota reports first anthrax case of 2023

Jul. 27—BISMARCK, N.D. — North Dakota State Veterinarian Ethan Andress says the state's first reported case of anthrax this year has been confirmed.

The case, in Grant County, was confirmed by the

North Dakota State University Veterinary Diagnostic Laboratory.

Andress said the diagnosis is a reminder to livestock producers to protect their animals, especially in areas with past issues with anthrax.

"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 state veterinarian's office will coordinate with local and state resources to assist producers in dealing with a disease situation.

Anthrax is caused by a spore-forming bacterium called Bacillus anthracis, which can emerge in greater concentrations after rainstorms, flooding, or excavation. Animals are exposed to the disease when they graze or consume forage or water contaminated with the spores.

Effective anthrax vaccines are readily available

, but it takes about a week for immunity to be established, and it must be administered annually for continued protection. Producers should monitor their herds for unexplained deaths and work with their veterinarian to ensure appropriate samples are collected and submitted to a diagnostic lab to give the best chance of obtaining a diagnosis.

"Anthrax has been most frequently reported in northeast, southeast and south-central North Dakota, but it has been found in almost every part of the state," Agriculture Commissioner Doug Goehring said. "A few anthrax cases are reported in North Dakota almost every year. The animals impacted included cattle, bison, horses, sheep, llamas and farmed deer and elk."

Two cases of anthrax were last reported in North Dakota in 2021

. In 2005, however, more than 500 confirmed deaths from anthrax were reported with total losses estimated at more than 1,000 head.

Minnesota earlier this month reported its first anthrax infections in more than a decade.

The cases, affecting cattle and a horse, were in northwestern Minnesota.
