BISMARCK, N.D. (AP) — A North Dakota official says state and federal veterinarians are investigating a case of tuberculosis in a young heifer from an Oliver County dairy herd. The heifer has never produced milk.
State Veterinarian Susan Keller says the case was found when the owner agreed to have the herd tested after an employee tested positive.
Keller says the U.S. Veterinary Service Laboratory in Iowa confirmed the tuberculosis diagnosis in the heifer. She says even if the heifer had produced milk, routine pasteurization would have prevented any contamination of the milk supply.
Tuberculosis can be transmitted from animals to humans and from humans to animals.
Keller says an investigation is now underway, and further testing will be done to determine the source of the disease and to prevent its spread.
