How long smoked turkey will last depends on if the meat is still attached to the bone. If the turkey is smoked and the meat is removed from the bone, it will keep in the refrigerator for up to 3 days. If you would like to keep it longer you can put it into the freezer. In the freezer, smoked turkey can last up to 6 months. Your senses are a reliable instrument for determining if a turkey is still good. A bad smoked turkey will be dull and have a sour smell.
