Health Issues Which May Affect This Animal

What Causes This Disease?

Trichinosis is a disease caused by a nematode parasite, Trichinella spiralis.

Where Is The Disease Found?

Trichinosis occurs throughout North American and can be found in grizzly bears, polar bears, black bears, feral swine, mountain lions, wolverines, wolves, coyotes, and foxes. Trichinosis has been documented in black bears and mountain lions in Idaho. Trichinosis has been documented in humans associated with consuming home-made jerky made from a cougar and a black bear in Idaho.

Signs of Disease

Animals infected with trichinosis generally appear healthy. Trichinosis is hard to detect when butchering because there are few lesions and the cysts are very small. The cysts are most common in the muscles of the jaw, tongue, and diaphragm. Animals that are infected with adult worms may have swollen intestines with small bruises on the intestinal wall. Affected muscles and associated lymph nodes may be soft and swollen.

    Mountain lions in Wood River Valley

    SUN VALLEY- This winter has been an interesting one for the Wood River Valley. After last year’s record snowfall, this year has nearly been the opposite, with very little snow.

    Fewer elk and mule deer are calling the river bottoms home due to the open hillsides, but many of the mountain lions that prey on them are still trying to carve out a living where they were finding abundant deer and elk populations last winter.

    Idaho Department of Fish and Game recently lethally removed two lions, one from the Freidman Memorial Airport and one from the Gimlet subdivision.
