TB investigated in North Dakota herd

A North Dakota beef herd is being tested for bovine tuberculosis, following the identification of a cow with a TB lesion at a Minnesota meat-processing plant, the North Dakota Agriculture Department says in a release.

“We are in the early stages of the investigation, and complete results of the herd tests won’t be known for several weeks,” state veterinarian Dr. Susan Keller said Dec. 5.

Keller said that a suspect lesion on the animal was detected through routine inspection at a processing plant in Long Prairie, Minn., and that pathological tests at the National Veterinary Services Laboratory in Ames, Iowa, confirmed the diagnosis of bovine TB. A traceback determined that the animal came from a livestock operation in southwestern North Dakota.

North Dakota has been officially TB-free since Jan. 1, 1976. Under federal guidelines, that status remains in effect. The last time a North Dakota herd tested positive for the disease was in 1999 in Morton County.
