What is the last day a product is considered fresh called?

The term that refers to the last day a product is considered fresh is the "Use By Date." This date is significant because it indicates the point at which a product is expected to maintain its best quality and safety. After the Use By Date, the product may not be safe to consume or may not perform as intended, be it in terms of taste, texture, or nutritional value.

Understanding the Use By Date is crucial for consumers to ensure food safety and to minimize waste by consuming products while they are still optimal for use. This date is particularly common for perishable items that can spoil quickly.

In contrast, the Best Before Date is generally a guideline for quality rather than safety, while the Expiration Date signifies when a product should not be consumed. The Sell By Date is mainly for retailers to manage inventory and does not necessarily indicate safety for consumers.
