Many foods have an expiry date (called an "expiration date" in the USA) because their ingredients will spoil if they are left on the shelf for too long. Some products have a very long "shelf life"-- they can be sold for weeks, or even months. But others are "perishable," which means if you do not buy them before their expiry date, they will no longer be healthy and in fact, you might get sick from eating them.
