Evidently you are not used to skinning and butchering your meals. Unless you wear gloves (which get in the way) you are almost certain to get some blood in the nicks and scratches on your fingers. Even if you keep your knife sharp and do not cut yourself, the briars and brambles you pushed through while hunting will almost certainly have opened up a small scratch or two on your hands.

Hi urban peasant,
Normally when people eat uncooked organ meats, they are showing off how tough they are to observers, not enjoying themselves. So the real danger comes during the initial preparaton of the food, before cooking it.
