Raspberries (and blackberries and all those similar) have a short shelf life which is why you rarely see them sold in stores. They might last a day or two but go bad fast (even with refrigeration.) Blueberries also go bad quickly but can last a bit longer. Yes, refrigerate them, but don't wait too long to eat.
How To Store Blueberries. You can store your blueberries in a number of ways. Before you store the berries, carefully go through the berries, discard any soft berries or berries with white areas on their skin, and remove stems. If you are planning to refrigerate or freeze your blueberries, do not wash the berries before you store them; wait to wash the berries until you are ready to use them. Cool your berries down to room temperature before storing them. By doing this, you can avoid a lot of condensation in the blueberry containers.
