Minnesota Anthrax Outbreak: Livestock Producers Advised to Vaccinate Animals

The Minnesota Board of Animal Health has confirmed the state's first case of anthrax in animals in over a decade. The incident, occurring in Kittson County, has affected multiple cattle and a horse, leading to the quarantine of the affected property.

In response to the detection, the Board strongly advises livestock producers, especially those in northwest Minnesota, to ensure their animals are up to date on anthrax vaccinations.

Dr. Katie Cornille emphasizes the importance of proactive measures like vaccinations in preventing anthrax cases. Livestock producers in Kittson County should consult with their veterinarians about anthrax vaccinations if not already implemented, as the rarity of such incidents in the state can be attributed to these preventative actions.

Anthrax, caused by Bacillus anthracis, is a spore-forming bacterium. Livestock, especially ruminants like cattle, sheep, and goats, are most susceptible to the disease during summer pasture grazing. Rapid progression of the disease makes it crucial to have a veterinarian examine animals that die suddenly or are discovered deceased on pasture.

Veterinarians should avoid field necropsies for suspected anthrax to prevent spore formation and contamination. Anthrax spores can endure in soil for extended periods, posing a threat to other animals. Reporting suspected anthrax cases to the Board of Animal Health is mandatory, ensuring appropriate carcass disposal to mitigate spore spread.

While anthrax in animals does not pose a risk to the public, the disease can be transmitted through contact with affected animals or their products. Although the risk is low, individuals who have come into contact with animals that have died from anthrax should consult their healthcare provider or reach out to the Minnesota Department of Health for guidance.

Minnesota livestock producers should be attunedto anthrax detection, ensure proactive vaccinations and report suspected cases. This will effectively contain and manage the disease, safeguarding animal health and minimizing risks to the agricultural community and public.
