food dates

"Sell by" tells the store how long to display the product for sale. You should buy this product before the date. "Best if used by" or "Best before" is a date recommended for best flavor or quality. It is not a purchase by or safety date. "Use by" is a date determined by the manufacturer as the last date recommended for use of the product at 'peak quality'. "Closed" or "coded" dates are packing numbers for use by the manufacturer.
