North Dakota has recorded its second case of anthrax in cattle this year.
A release from the state says a North Dakota State University lab on Tuesday confirmed a beef bull from northwestern Dickey County had anthrax.
In May, an anthrax case was confirmed in eastern Sioux County.
State veterinarian Susan Keller is urging producers to have their cattle vaccinated against the illness and to report unexpected deaths in their herds to veterinarians.
Anthrax bacteria spores lie dormant in the ground and become active under conditions such as heavy rainfall, flooding or drought.
North Dakota usually has a few anthrax cases every year. In 2005, the disease resulted in an estimated 1,000 dead cattle, bison, horses, sheep, llamas and farmed deer and elk.
