South Dakota Confirms First Anthrax Case of 2026 in Meade County Beef Herd

Northeast Radio SD News – South Dakota - Anthrax has been confirmed in a South Dakota beef herd currently located in Meade County, according to a news release from the South Dakota Animal Industry Board. This marks the first confirmed case of anthrax in 2026.

State Veterinarian Dr. Mendel Miller says the cow/calf herd first began experiencing unexplained deaths while pastured in Butte County, where exposure is believed to have occurred. The cattle were later moved to Meade County, where symptoms continued. In response to the diagnosis, adult cattle in the herd have now been vaccinated.

The Animal Disease Research and Diagnostic Laboratory at South Dakota State University confirmed the disease using samples submitted by the herd’s veterinarian. The Animal Industry Board has quarantined the affected herd, notified neighboring herd owners, and will quarantine any additional herds if needed.

“Veterinary oversight is important when faced with disease concerns, and the Animal Industry Board will continue to work with ranchers and private veterinarians to quickly respond to anthrax,” Dr. Miller said, noting that the anthrax vaccine remains an effective tool for herd protection.

Officials urge ranchers to contact their local veterinarian or the Animal Industry Board at 605‑773‑3321 if anthrax is suspected. They also warn producers not to move carcasses until a diagnosis is made, emphasizing that proper handling — including burning and burying — is critical to preventing further spread.

Anthrax is a rapidly fatal livestock disease, and spores can survive indefinitely in soil. Significant weather events such as drought, flooding, or high winds can increase exposure risk.
