- **Which Date Should Be Seen on High-Risk Perishable Food?** When dealing with high-risk perishable foods, understanding the different types of dates printed on packaging is crucial for ensuring food safety and minimizing waste. Here are the key dates to consider: – **Use-By Date:** This is the most critical date for high-risk perishable foods. It indicates the last date the product is safe to consume. Consuming food past this date can pose health risks due to potential bacterial growth. – **Sell-By Date:** This date is primarily intended for retailers. It tells stores how long they should display the product for sale. While the food may still be safe to eat after this date, it is best to consume it soon after purchase. – **Display Date:** Sometimes used interchangeably with the sell-by date, the display date guides retailers on when to put the product on shelves. It helps manage stock rotation to ensure freshness. – **Today’s Date:** This is not typically printed on packaging but can refer to the current date when checking the product. Consumers should always compare today’s date with the use-by date to determine if the food is safe to eat. In summary, for high-risk perishable foods, the **use-by date** is the most important to observe for safety reasons. The sell-by and display dates assist retailers in managing inventory, while consumers should always check today’s date against the use-by date before consumption.
