Cooked turkey can last up to 3 to 4 days inside the refrigerator (40 °F or below). If you put it in the freezer (0 °F or below), it can last up to 4 months.
Refrigerate cold food as soon as you get home (always within 2 hours). Serve your meal within 3 to 4 days.
Reheating a Whole Turkey is NOT Recommended. If you plan to reheat a turkey, cut the meat into smaller pieces. Slice breast meat. Legs and wings may be left whole. Refrigerate in shallow containers.
Exception: Cooked turkeys with the USDA inspection seal on the packaging have been processed under controlled conditions. Follow package directions for reheating and storing.
