I think humans in general can eat raw meat. It just doesn't give as much calories compared to cooked meat, plus more chance of diseases which would've been sorted out by the heat if it was cooked.
That's why it "doesn't give as much calories." It actually gives the same amount of calories, we just expend more calories digesting raw meat. Cooking the meat is also referred to as "freeing up" calories.
In Poland it is quite common in restaurants.
