Many Americans throw away perfectly good food due to label confusion. This contributes 398,000 tons of food waste each year. “Best by” labels indicate when the manufacturer believes the food should be used for best quality, NOT food safety. “Use by” and “sell by” dates are similar for shelf stable foods; these dates tend to reflect quality, not food safety. However, “use by” and “sell by” dates on refrigerated items do indicate when the food may begin to spoil. Don’t use refrigerated foods that are past the “use-by” or “sell-by” date. If a food product is nearing the indicated date, you may be able to freeze it to extend its life.
