Unopened Cool Whip should be safe to consume for about 2 to 3 weeks when stored in the refrigerator. It's important to check the "Best By" or "Use By" date on the packaging to get an exact idea of its shelf life.
Always follow the storage guidelines provided by the manufacturer. Once opened, the Cool Whip should be used within a week or as recommended on the package. If you notice any changes in color, texture, or an off odor, it's best to discard it, as these are signs that the product may have spoiled.
Remember that proper storage conditions are essential to maintaining the quality and safety of any food product. Keep Cool Whip refrigerated at all times, and avoid leaving it out at room temperature for extended periods.
