What is the meaning of "use by" dates on food packaging?

The "use by" date on food packaging serves as a guideline for consumers, indicating the last date recommended for the use of the product to ensure optimal quality. This date is based on the manufacturer's guarantee that the product will maintain its best flavor, texture, and nutritional value if consumed by that point. It is important to note that while food may still be safe to eat shortly after this date, the quality may not meet the manufacturer's standards.

This designation focuses on quality rather than safety; thus, foods can often remain safe for consumption beyond the "use by" date, depending on various factors such as storage conditions and the specific nature of the food item. Understanding this distinction helps consumers make informed decisions about food consumption and waste, allowing them to enjoy products at their best while being mindful of safety practices.
