Chronic Wasting Disease

A moose in Montana has tested positive for chronic wasting disease (CWD) for the first time. The finding expands the area wildlife managers believed the disease to exist.

The moose was killed north of Troy, just a half of a mile outside of the Libby CWD management zone, which spans a 10-mile radius around Libby. Thirty white-tailed deer have tested positive for CWD within the management zone since the disease was discovered this spring.

Montana wildlife officials say a mule deer buck harvested during archery season northeast of Joliet tested positive for Chronic Wasting Disease.

Both deer and elk rifle hunting seasons opened across the state Saturday and hunters hiked into the woods at the crack of dawn in the hopes of coming out with some fresh meat to stock their freezers. That ritual was a little different this year for hunters in the Libby area, where chronic wasting disease (CWD) has been detected in white-tailed deer.

The number of white-tailed deer infected with Chronic Wasting Disease continues to climb in Libby. Eighteen white-tailed deer have now tested positive since the count started this spring.

Hunter-harvested deer are expected to shed more light on the spread of the disease when general rifle season starts later this month.

Montana officials are expanding restrictions on the transport of big game animals to prevent the spread of a fatal disease.

State game managers say another white-tailed deer is likely positive for Chronic Wasting Disease in Libby. If confirmed, this would be the tenth deer to test positive since the spring.

It’s been two years since Chronic Wasting Disease (CWD) was detected in Montana’s deer herds, and in May the disease popped up in the northwest corner of the state in Libby. Montana Fish, Wildlife and Parks (FWP) has a plan to manage the fatal disease based on its prevalence, a strategy born from more than 20 years of trial and error across the country.

The Montana Department of Fish, Wildlife and Parks is wrapping up a series of public meetings on Chronic Wasting Disease, or CWD. This week, the agency explained its initial management strategy for the Libby area where six white-tailed deer have tested positive for the fatal disease.

CWD was detected in Libby this spring. It’s the first case of the disease showing up in a wild herd in western Montana.

Hundreds of white-tailed deer tags for a special chronic wasting disease (CWD) hunt near Libby sold out in about two hours Monday. The Montana Department of Fish, Wildlife and Parks says the hunt will help managers understand the prevalence of the disease and reduce its spread.

Montana Department of Fish, Wildlife and Parks is looking to understand how widespread chronic wasting disease in Montana by stepping up sampling efforts with white-tailed deer this hunting season.

The initial detection of chronic wasting disease, or CWD, west of the Continental Divide happened near Libby in late May. Since then, five deer have tested positive for the disease. So far the disease has only been confirmed in wild deer in Montana.
