It is important to understand the different expiry dates correctly.
Food can pose a risk to health if consumed after the use-by date. Once this date has passed, the product in question is to be considered to be unfit for consumption and must no longer be frozen. Examples of this type of product include meat or fish.
This type of expiry date is used by the manufacturer to indicate that the product will retain its quality and taste until the date shown. Foods with this type of expiry date can often still be consumed after that date. Check, smell and taste them to see if they are still good. Examples of this type of food include pasta, biscuits, coffee, rice, etc.
