According to the Food Safety and Inspection Service of the U.S. Department of Agriculture, luncheon meats such as bologna can stay fresh in the refrigerator for up to two weeks when left unopened. Opened bologna packages left in the refrigerator are good for three to five days.
Bologna is a variety of sausage that must be kept refrigerated. Bologna can also be frozen for up to two months in the freezer.
Generally, in order to determine the freshness dates of lunch meat, one should check the date determined by the manufacturer. This date is typically printed on the outside container of the product.
