Meat with a bone in it would be "on the bone", as opposed to boneless
meat. When you cook meat with a bone, the bone retains cold longer and
makes it take longer to cook. Also, there can be pockets of less done
meat next to the bone, which is what I think the reasoning is for the
suggestion. Underdone meat might not get rid of the disease organisms.
