Q: “How long is it safe to keep open jars of food or sauce in the fridge? -Michelle Simutis

Food “best by” dates guide:
- A “Sell-By” date tells the store how long to display the product for sale. You should buy the product before the date expires.
- A “Best if Used By (or Before)” date is recommended for best flavor or quality. It is not a purchase or safety date.
- A “Use-By” date 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.
- “Closed or coded dates” are packing numbers for use by the manufacturer.
