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.
1 Pineapple â Store it at room temperature to ripen, then refrigerate for 3-5 days. Cut up pineapple will last 3-4 days in the refrigerator.  Raspberries â Discard bruised or moldy berries before storing. Store in the refrigerator (top shelf), in a shallow container, covered with plastic wrap.
