A system and method for storing and selecting animal carcasses within a cooler. A storage area has at least one storage loop forming a continuous loop upon which carcasses may circulate. A feed rail leads to the storage area. A loop entry rail branches from the feed rail onto each storage loop. A removal rail intersects each storage loop and leads to an exit rail. Each carcass may have an identification tag. Readers read the tag and a processor and database store and process information associated with the tag. Carcasses enter the storage area via the feed rail and are routed onto the loop entry rail of the storage loop having the greatest available capacity. When carcasses meeting specific criteria are desired, the database is searched and the processor causes the appropriate carcasses to circulate to the removal rails. The carcasses exit the storage loops onto the removal rails.
