The most tender and flavorful skeletal muscles of the cow become roasts, steaks and racks of ribs. Poor-quality cuts and meat scraps are often combined with fat trimmings to create jerky, burger and sausages. Milk is the best recognized by-product of cattle. The majority of a cow's organs are safe to eat, including liver, heart, kidneys, brains, tripe, pancreas, tongue and testicles.
