What is the purpose of the "sell by" date on food products?

The "sell by" date on food products serves to indicate the last date by which the product should be sold in order to ensure that consumers receive it at its best quality. This date helps retailers manage their inventory and make decisions on what to stock while providing consumers with information on freshness. Although products may still be safe to consume after the "sell by" date, quality may start to deteriorate, impacting taste, texture, or nutritional value.

This date is particularly important for perishable items like dairy and fresh produce. It encourages stores to rotate their stock and remove items that are nearing this date, ultimately ensuring customers have access to the best possible products. Understanding this system helps consumers make informed decisions, while also maintaining the integrity of food in the marketplace.
