28 Facts About Expiration Dates

What Are Expiration Dates?

Expiration dates are everywhere, from food to medicine. They tell us when a product is no longer at its best. But how much do you really know about them?

1. Expiration dates are not always about safety. They often indicate when a product is at its peak quality.

2. "Best by" dates suggest when a product will taste best. It doesn't mean the food is unsafe after that date.

3. "Sell by" dates help stores manage inventory. They guide when to remove items from shelves.

4. "Use by" dates are the last dates recommended for using a product at peak quality. They are more about quality than safety.

Understanding Expiration Dates

Knowing the facts about expiration dates can save money, reduce waste, and keep you safe. Many people toss out food and products prematurely, thinking they're no longer good. But often, items are still safe to use past their printed dates. "Best by" dates indicate peak quality, not safety. "Sell by" dates help stores manage inventory, not necessarily when you should throw something out. "Use by" dates are the manufacturer's suggestion for best flavor or quality.

Always use your senses—look, smell, and taste—before deciding to discard something. Trust your judgment. Proper storage can extend the life of many items, too. Refrigerate perishables promptly, keep dry goods in cool, dark places, and follow any specific storage instructions on the packaging.

By understanding these facts, you can make smarter decisions, reduce waste, and ensure you're getting the most out of your purchases.
