A widespread outbreak of a disease affecting deer, elk and antelope forces Fish, Wildlife & Parks officials to consider making changes to hunting regulations.
FWP officials said epizootic hemorrhagic disease, or EHD, and bluetongue disease are common east of the continental divide.
However, this year, reports of dead white-tailed deer and antelope have been more widespread, even as far as Missoula.
FWP officials said they may recommend reductions in deer regulations in some parts of the state.
Vivica Crowser, of Fish, Wildlife & Parks, said, "We've had over 200 deer that were found dead between Missoula and Frenchtown that we expect are EHD positive. We're still waiting on the lab confirmation of that. That we expect this week."
EHD and bluetongue are naturally occurring viruses that cause bleeding within an animal.
Officials said humans can't contract the disease, so it's safe to handle and eat meat from infected animals.
