From 1998 to 2016, Montana tested more than 17,000 wild deer, elk and elk for CWD. There was no positive evidence, until this fall.
A mule deer shot by a hunter on November 12 north of Chester on the Hi-Line line near the Canadian border tested positive on the proof of chronic attrition disease, according to Montana Fish, Wildlife and Parks.
The deer was captured in hunting district 401 in Liberty County, in a very remote country less than 10 miles from the Canadian border, said Bruce Auchly, spokesman for FWP in Great Falls.  The results of the test mark the fifth CWD incident discovered in wild deer in Montana this fall, but the first in northern Montana.
The other four deer came from the south of Billings.
"This was not unexpected in that CWD is on three sides of us: Alberta and Saskatchewan, the Dakotas and Wyoming," Auchly said.
Until this year, CWD had not been found in Montana, although the disease exists in herds of wild deer in Wyoming, North and South Dakota, Saskatchewan and Alberta.
The results arrived on Monday.
A hunter shot the deer and FWP took samples.
He had a radio collar because it was part of a study of the mule deer movement in the area, Auchly said.
As a result, FWP officers knew he had died when the animal stopped moving.
Chronic wasting disease, or CWD, is a progressive and fatal neurological disease of moose, deer, elk and caribou, for which no cure is known.
The name comes from the appearance of symptomatic animals, which become very thin and sickly appearance before dying.
The people of Montana and those interested in big game here have not yet really understood the impact that CWD represents for the wild ungulate populations of the state, according to a response plan from FWP to CWD.
moves slowly through the populations.
However, if not managed, the population could decrease in the long term, affect the value of the properties and reduce interest in deer hunting and the $ 400 million in income generated by deer, elk and antelope. , according to FWP.
Transmission to humans is not known, says FWP.
However, the World Health Organization and the Centers for Disease Control and Prevention recommend not consuming meat from an animal. It is known that I am infected with CWD.
In addition, the CDC recommends that hunters consider having their animals tested before eating meat when they hunt in areas where CWD is known to exist.
Four deer tested positive previously after being shot in Carbon County in southern part of Montana near the southern border with Wyoming.
A mule deer died at the end of October, 10 miles southeast of Bridger, and a second mule deer died in early November, 3 miles south of Belfry.
A mule deer harvested southeast of Bridger and a white-tailed deer shot east of Joliet also tested positive.
The initial discovery of CWD prompted FWP director Martha Williams to form an incident command team, which will implement the department's CWD response plan.
FWP proposes a special two-month hunt for mule deer in Carbon County to measure the prevalence of CWD in the area.
The Montana Fish and Wildlife Commission is scheduled to vote on Thursday on the proposed search.
The search will be divided into two sessions: from December 15 to January 14 and January 14 to February 15
FWP is in the process of assembling a team for the last detection north of Chester, said Auchly
It has not yet been determined if there will be a special CWD hunt north of Chester, he said.
As of 2017, CWD had been found in captive or free herds in 24 states, three Canadian provinces, Norway and South Korea.
It was first discovered in 1967 in the mule deer in a research facility in Colorado. Its origin is unknown.
Soon after, captive mules and moose were also found in deer in Ontario, Colorado and Wyoming.
In the 1990s it was discovered in white-tailed deer and mule deer, elk and elk in Colorado and Wyoming and among captive animals in Saskatchewan, South Dakota, Montana and Oklahoma.
In the early 2000s, CWD was found free in Saskatchewan, Alberta, Illinois and Wisconsin.
Once CWD is present in a wild population, it is extremely difficult, if not impossible, to eliminate, said FWP.
New York and perhaps Minnesota may be the only two states that have eliminated an outbreak of CWD after its detection.
Both responded aggressively to what appears to have been very early and small outbreaks, FWP said.
In general, the CWD is discovered after it has been established for some time.
The incubation period of approximately 16 months, "When an animal is infectious and releases potentially long-lived prions into the environment, it makes it difficult to detect an emerging epidemic before it is well established," FWP said.
There are currently no effective treatments or vaccines for CWD, said FWP.
Prevention is fundamental for the control of CWD in large landscapes.
Preventive tools include restricting the transport of corpses from areas or states infected with CWD, prohibiting the transport or translocation of wild deer or deer and other cervids, and demanding the responsible disposal of corpses from infected regions, said FWP .
Many states have tried to combine the reduction of population density, the sacrifice of diseases and the reduction of large concentrations of deer or elk to control the spread.
Some simple precautions should be taken when wearing deer, elk or elk, according to FWP:
»Wear rubber gloves and eye protection when dressing in field.
»Minimize the management of the brain and spinal tissues.
»Wash your hands and instruments thoroughly after the bandage is completed in the field.
»Avoid consuming brain, spinal cord, eyes, spleen, tonsils and lymph nodes of harvested animals. (The normal field dressing together with the deboning of a carcass will essentially eliminate these parts.)
