hi smokesman, my timeline has it such, that when the finished meat is ready to get rested the other raw comp meat is coming out of the cooler so it is then washed and ready. as far as putting some MOINKballs and beers and water in the same cooler for personal consumption i don't see too much issue really, as long as you're careful with packaging. there is food-safe certification among my team and sanitation and cleanliness are top priorities. as they should be.
but, might be easier the way you do it.
