Just looked on a recently purchased can of Underwood Deviled Ham. It has an expiration date of January 19, 2013. Has more fat than protein. However in a survival situation, you will need fat in your diet so you could stock up on something like this and rotate it out. Not enough an it will kill you. I read about someone who survived in the wilderness for about 2 weeks on rabbit, and he was severly needing fat. Doctor said he would have died if not found in about a week due to lack of fat in his diet. Guy did not eat the internal organs like the liver and heart, but only the legs and muscle meat which was extremely lean.
