Michigan Hunter Warning: Test Your Deer for Bovine Tuberculosis

While one of the longest periods of state deer hunting begins, the Michigan Department of Natural Resources warns hunters to closely monitor bovine tuberculosis that can be detected in animals.

The ministry has labeled bovine tuberculosis an "emerging disease" that recently hit a large herd of cattle in Alcona County, Michigan. According to the Associated Press, it is the 73rd herd of cattle to be identified with bovine tuberculosis in the state since 1998.

Bovine tuberculosis is a bacterial disease that mainly affects livestock. However, other animals such as deer can be infected, according to officials of the state. Food contaminated with the saliva of an infected tuberculous animal can spread the disease.

The first archery session of the Deer Hunting Season in Michigan began on October 1st and will last until November 14th. The hunt for the firearm lasts from November 15 to 30.

Dan O 'Brien, a veterinarian specializing in the agency's Wildlife Disease Research Laboratory, said that this year was not unusual, but that it needed to be conscious to hunt and consume deer.

"We have been testing for over 20 years," said O & Brien at CBS News. "It's at a low level but it's still there – it's a concern, absolutely."

Bovine tuberculosis can develop in the lungs, but it can also be found in the intestines and other parts of the body, according to the Michigan Department of Natural Resources. The agency warns hunters of the presence of swollen or infected lymph nodes in the animal's head or lesions throughout the body. Deer with severe tuberculosis may have yellow or tanned lumps lining the chest wall and lung tissue.
