The smaller of the two zones was classified as nonmodified accredited because of the prevalence of tuberculosis among cattle in that zone exceeded the level allowable for modified accredited status. The larger zone, which consisted of most of Michigan, was classified as accredited free. Since November 1999, Michigan has detected tuberculosis in wildlife in several areas outside the nonmodified accredited zone. Because of these detections, Michigan has determined that it can carry out its tuberculosis control and eradication program more effectively with a single set of statewide requirements for movement of livestock.
Bovine tuberculosis is a contagious, infectious, and communicable disease.
It affects cattle, bison, deer, elk, goats, and other species, including humans. Bovine tuberculosis in infected animals and humans manifests itself in lesions of the lung, bone, and other body parts, causes weight loss and general debilitation, and can be fatal. This interim rule was effective June 22 and is scheduled for publication in the June 28 Federal Register. Consideration will be given to comments received on or before Aug. 28.
