Use by意思

"Use by" is a phrase commonly found on food packaging and labels, indicating the date until which the food product is safe to consume. It is a safety date, meaning that the food is likely to lose its quality or may become unsafe to eat after that date. Consumers are advised not to consume any food past its "use by" date.

The "use by" date is typically determined by the manufacturer or food producer based on the food's shelf life, taking into account factors such as the product's moisture content, pH level, and the presence of any preservatives. This date is often used for perishable items that are more susceptible to spoilage, such as meat, dairy products, and ready-to-eat meals.

It's important to note that the "use by" date is different from the "best before" date, which is an indication of quality rather than safety. Foods past their "best before" date may not taste as fresh or have the same texture, but they are generally safe to eat if they have been stored properly.

When a food product reaches its "use by" date, it should be discarded to avoid the risk of foodborne illness. Consumers should always check the "use by" date before purchasing and consuming food items to ensure they are consuming them safely.
