DEER MANAGEMENT ISSUES BAITING / SUPPLEMENTAL FEEDING

    In Michigan, where bovine Tuberculosis exists in wild deer and elk, scientists believe that the maintenance of bovine TB in white-tailed deer is directly related to supplemental feeding/baiting and the increased focal densities these practices create. The unnatural circumstances of supplemental feeding promote inhalation of bovine TB bacteria or consumption of feed contaminated with the bacteria from animals coughing and exhaling.
  • Bovine tuberculosis – a disease still worth fighting, UPMatters.com, July 6, 2017After more than two decades of study and testing white-tailed deer for bovine tuberculosis, Michigan has become world-renowned for its research and expertise on managing this serious contagious disease. There are several types of tuberculosis, but bovine tuberculosis (bTB) can infect the widest variety of animals and is what wildlife managers have been trying to eradicate from white-tailed deer in Michigan.
  • Can chronic wasting disease jump from deer to humans? Concerns keep rising, Milwaukee Journal-Sentinal, July 10, 2017In 2002, the year CWD was discovered in Wisconsin, six cases of Creutzfeldt-Jakob disease were recorded, according to the state Department of Health Services. In two of the last four years, 13 cases have been recorded. That’s a 117% increase.
  • DNR update on impact of Newaygo County bovine TB finding on area hunters, MI DNR, March 17, 2017Voluntary deer check is only change hunters will see due to bovine TB-positive steer
    Earlier this week, the Michigan Department of Agriculture and Rural Development announced the finding of bovine tuberculosis (TB) in a sample taken from a 2-year-old steer from Newaygo County. The animal was identified as possibly diseased and removed from the human food chain by the U.S. Department of Agriculture Food Safety Inspection Service. Bovine TB is a bacterial disease that can be spread between wildlife populations and other mammals, including humans. In Michigan, TB is primarily found in the northeast Lower Peninsula.
  • Deer Hunters in SE Indiana Face Bovine TB Testing on Deer, AGWeb, Nov 11, 2016The animal disease was detected in August in a wild deer in neighboring Franklin County, marking the first such discovery of the disease in Indiana history.
  • Deer Check-In Rules in Dearborn and Franklin Counties, WRBIRadio.com Indiana, Nov 11, 2016The DNR has established a bovine tuberculosis surveillance zone in Dearborn County north of State Road 48 because the disease has been detected in a wild deer in neighboring Franklin County.
  • Two TB-positive deer trigger need for cattle testing, Michigan Farmer, Feb 15, 2015Cattle and bison farms in Presque Isle County and Cheboygan County townships within a 10-mile radius around the Presque Isle County TB positive deer will be tested in the next six months. Cattle farms in the Modified Accredited Zone are already TB tested on an annual basis, so there is no additional TB testing required in those townships.

  • Bovine Tuberculosis, Michigan Department of Natural ResourcesBovine TB is spread primarily through the exchange of respiratory secretions between infected and uninfected animals. This transmission usually happens when animals are in close contact with each other. Thus, animal density plays a major factor in the transmission of M. Bovis.
  • Managing the wildlife reservoir of Mycobacterium bovis: The Michigan, USA, experience, 4th International Conference on Mycobacterium bovis, 2006White-tailed deer, the primary reservoir and maintenance host of tuberculosis, are highly valued by the public, and particularly hunters, for cultural and economic reasons. Since 1995, significant progress has been made in defining and reducing the reservoir of tuberculosis in deer. As yet, no other wildlife species has been shown to play an epidemiologically important role in the disease cycle. The importance of deer and deer hunting to Michigan has uniquely shaped tuberculosis control policies, and poses ongoing challenges as wildlife managers strive to maintain momentum for broad control strategies, and develop focused strategies that are publicly acceptable.
