The shelf life of Starburst candies can vary depending on a few different factors, such as the specific product, storage conditions, and the packaging. In general, unopened packages of Starburst candies can last for 6 to 12 months, while opened packages may last for 3 to 6 months if they are stored in a cool, dry place and properly sealed. However, the quality and texture of the candies may degrade over time, especially if they are exposed to moisture or heat.
It's always a good idea to check the expiration date on the package and use your best judgment when deciding whether or not to consume a particular candy. If you notice any signs of spoilage, such as a strange odor, a change in color, or a sticky or slimy texture, it's best to dispose of the candy and avoid consuming it.
