Trichinosis possibilities should be at the back of your mind when eating bear and other predators. CDC says 160F for safety.

The older the bear, the more likely it has been parasitized by the trichenella organism/s. Trichinosis most likely won’t kill you, but you will feel very ill. Sorta like the flu, but instead of your joints aching from a viral flu, along with fever, chills and malaise, it’s the muscle pain fever, chills and malaise. That muscle pain is from all those nasties embedding their cysts into your muscle.
I have decided that I’m not gonna eat or serve under-heated bear meat. Stew, roast and sausage cooked to temp for me.
PS: ….it’s the CDC, why shouldn’t we take them at their word??
