re: what is the longest you have left deer meat in ice chest on ice?

Beef is not considered aged until it's 21 days old. All choice steaks served in restaurants are aged. Wet aged meat, which is meat vacuum sealed and refrigerated, can be aged upwards of 60 days. Best steak I've ever eaten was a filet from a loin I let age for 82 days. As long as you keep the meat refrigerated between 33-36 degrees or on ice you will be fine.
