If the sausage has a “use-by” date, follow that date. It is the last date recommended for the use of the product while at peak quality. The date has been determined by the manufacturer of the product. If the sausage has a “sell-by” date, or no date, store it for the times recommended below. Freeze sausage if you can’t use it within the times recommended for refrigerator storage. Once frozen, the USDA recommends storing frozen sausage for 1-2 months.
