Breakfast sausages are not cured or smoked like other types of sausages, which means that they have to be cooked soon after they are purchased (unless they are frozen). Uncooked sausages should be stored in the refrigerator or the freezer. Individuals handling them should wash their hands in hot soapy water, because uncooked pork is unhealthy for humans. Pork sausages have to be heated until all of the meat inside is cooked.
