How can you tell if cool whip or pudding is spoiled?

To determine if Cool Whip or pudding is spoiled, check for changes in color, texture, or smell. If you notice any off-putting odors, a watery layer on top, or an unusual consistency (like separation or curdling), it's best to discard them. Additionally, always check the expiration date; if it's past that date or if the product has been opened for an extended period, it's safer to throw it away.
