Grazing livestock in northwestern Minnesota at risk for anthrax

ST. PAUL, Minn. - Producers in northwestern Minnesota are urged to vaccinate their cattle soon against naturally occurring anthrax.

"Before producers turn their cattle out on pasture this summer they should consider vaccinating for anthrax,"

said Minnesota Board of Animal Health Executive Director and State Veterinarian Dr. Bill Hartmann. "Cattle

that graze can be exposed to anthrax spores in the soil. Vaccination is an inexpensive way to protect your

cattle."

Anthrax is a naturally occurring disease caused by the bacteria Bacillus anthracis. The bacteria can lie

dormant for years in the soil. However, heavy rains and flooding can bring the spores to the surface, where

they may be ingested by grazing animals. Livestock infected with anthrax die quickly, often exhibiting no

symptoms until just before death.

As an added precaution, Hartmann recommends producers assume that any unexpected death among their

herd is due to anthrax until the disease can be ruled out. Suspect carcasses should not be cut open, because

that can allow anthrax to spread. If you suspect anthrax contact your veterinarian immediately.

Fortunately, the risk of humans developing anthrax from naturally occurring bacteria is extremely low.

Minnesota has recorded no human cases of anthrax since 1953.
