What does the "use by" date on food products signify?

The "use by" date on food products specifically indicates the date until which the food is expected to remain safe to consume and maintain its peak quality. This is particularly important for perishable items that can pose a risk of foodborne illness if consumed after this date. The manufacturer establishes this date based on testing that ensures the food remains safe to eat and retains its optimal taste and texture up to that point.

This date is crucial for consumers to understand, as it helps guide them in making safe choices regarding food consumption. Foods consumed after the "use by" date may not only lose quality but could also be unsafe, depending on the type of food and how it has been stored. This differs from other dates such as "best before," which usually relates more to quality than safety, or arbitrary dates which might not be tied to specific safety assessments. Therefore, recognizing the significance of the "use by" date helps maintain food safety and prevent foodborne illnesses.
