All food should be discard immediately if it is past code date true or false?

False. The expiration date on food products is a guideline provided by the manufacturer to indicate the date until which the product is expected to be at its best quality. It does not necessarily mean that the food is unsafe to consume after that date. Many foods can still be safe to eat even after the expiration date, depending on factors such as storage conditions and the type of food. It is important to use your senses (smell, sight, and taste) to determine if the food is still good to eat.
