Best before & use by dates. Food labels have date marks to inform us about their shelf life. The marks tell how long food can be kept before it begins to deteriorate.
There are different kinds of date markings, depending on the product. The most common terms are “best-before” dates, “packaged on” dates, and expiration dates. Knowing what these terms mean will help you understand the labels, which in turn will help you make informed choices about the food you buy.

This information is usually found on the label with the words “best before” and “meilleur avant”. The best-before date indicates to consumers that if the product has been properly handled stored under conditions appropriate to that product , the unopened product should be of high quality until the specified date.
