उत्तर
While purchasing canned food, their expiry date should be checked because an expiry date indicates for how long a canned food is safe for consumption. Canned foods with expired dates are not considered worth consumption as they could affect your health. They might get contaminated with microorganisms like bacteria or may have no nutritional value left after their expiration.
