Bovine tuberculosis refers to infection with bacteria called Mycobacterium bovis, or M. bovis. Mycobacterium bovis is related to another organism that causes tuberculosis in humans, Mycobacterium tuberculosis, but M. bovis is found most commonly in cattle and other animals. People can become infected with M. bovis when they consume raw milk and unpasteurized dairy products. Symptoms of bovine tuberculosis in people depend on the parts of the body infected; most infections result in no or only mild symptoms, including fever, night sweats, abdominal pain, and diarrhea. A comprehensive testing program conducted by the U.S. Department of Agriculture, state animal health agencies, and livestock ranchers has virtually eliminated bovine tuberculosis from cattle in the United States. However, bovine tuberculosis remains common in many developing countries, and persons should refrain from consuming imported dairy products that are not pasteurized.​
