These are general guidelines from the USDA’s FoodKeeper data for food stored at safe temperatures: fridge at 40°F (4°C) or below, freezer at 0°F (−18°C). Freezer times are for best quality; food kept constantly frozen at 0°F stays safe longer. Always check the package and the food itself. When in doubt, throw it out.
