The Nebraska Agriculture Department says a case of bovine tuberculosis has been diagnosed in a cow from a small herd in Knox County.
The announcement was made by the department on Tuesday. The rest of the herd was quarantined and tested negative for the disease.
The Associated Press reports federal experts are assisting the department in deciphering how the animal was infected.
Earlier this month, the USDA announced new plans to help control bovine TB by developing and improving diagnostic tests, vaccines and other technology to detect and prevent the spread of disease.
Infection rates of bovine TB in cattle are low, but the disease persists in wildlife which can then be transmitted to cattle.
