Definitely do NOT eat it. Quite often, the liver is the first internal organ that will show there is something wrong in the body. This is why my parents woulld never order liver. Itcleans the bood, and they did not know how healthy the animal was or whatthe liverlooked like before it was cooked. We had our own beefwhich we butchered ourselves. Dad would always check the liver over very well (ours were always very nice).
