Now that we've got the time limit out of the way, let's talk about the refrigerator rules. First, make sure your fridge is set at 40°F (4°C) or below - any higher, and you're inviting bacteria to the party. Also, store the turkey in a covered container on the middle or bottom shelf to prevent any juices from dripping onto other foods.
And, please, for the love of all things culinary, don't wash the turkey before storing it - you'll only end up splashing bacteria around and making a mess. Just pat it dry with some paper towels, and you're good to go. Oh, and one more thing - keep it away from strong-smelling foods like fish or onions, or your turkey will end up tasting like a seafood paella!
