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

The "use by" date on food products is an important indicator that signifies the last date for optimal quality and safety. This date is set by manufacturers to ensure that consumers use the product while it is still safe to consume. After the "use by" date, the product may begin to deteriorate in quality, which can include changes in texture, flavor, and nutritional value. More critically, consuming food past this date may pose health risks due to potential bacterial growth or spoilage.

This date is particularly significant for perishable items, where the risk of foodborne illness is higher. It is not merely a suggestion for best flavor, as it directly relates to safety. While some products may remain safe for a short period past this date, the manufacturer is not liable for quality or safety once the "use by" date has passed.

Other potential answers do not capture the same level of urgency or safety concerns associated with the "use by" date. Some may relate to general freshness or quality, but they do not specifically address the critical aspect of food safety in the way the "use by" date does. Understanding this distinction is key for food safety management, ensuring that food is consumed within a timeframe that maximizes safety and quality for consumers.
