| USDA tips: Pantry: Refrigeration ensures that commercial sauces and condiments stay fresh for a longer period of time. Shelf-stable commercial salad dressing is safe when stored at room temperature after opening. Quality, not safety, is the reason the labels on these products suggest that they be refrigerated after opening. | |||

Get early accessThese 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.
