Saddlesore is like usual a very good source of information. The not opening the thoracic or abdominal cavity prior to removing the limbs back straps and exterior rib meat is a most practical way for optimum meat recovery with minimum chance of bacterial contamination.
IMO
On a side note I applaud saddlesore for his perhaps extraordinary paitience and tolerance in sharing his wealth of knowledge.
