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.
Note: Nut oils always need to be refrigerated. 1  Olive oil and other oil-based products should be refrigerated unless you use them up within a month. 2  Butter should always be refrigerated. 3  Baby foods need to be refrigerated after opening.  Canned items should always be placed in the refrigerator once opened.
