Bovine tuberculosis testing

A DNR lab worker removes lymph nodes from a deer head for disease testing.

As a responsible hunter, you understand the importance of monitoring the health of the deer herd for diseases like bTB. Fortunately, you can take your deer to a staffed disease sample submission site or unstaffed drop box to have your deer tested for bTB. We are here to provide you with the necessary information to help you make an informed decision about bTB testing to keep our deer population healthy and sustainable.
