It’s a Date
Those printed dates on our food products can spark confusion at the grocery store and at home. The confusion can come with terms such as “sell-by” or “use-by” among others. Understanding these terms is important when you’re trying to reduce food waste and save money. The following terms will help you make choices about what to buy and how long to keep it.
Sell-By: The sell-by date is determined by the food product manufacturer and is often found on perishable items like meat, seafood, poultry, and milk. It informs the store of how long the product should be on display. You should buy a product before the sell-by date. You can still store the item at home beyond that date, as long as you follow safe storage procedures. For example, milk will generally be safe to drink one week after the “sell-by” date on the package, assuming it has been continuously refrigerated at or below 40°F.
Use-By, Best if Used By, Best By, Best Before: These “use-by” and “best” dates are generally found on shelf-stable products such as ketchup, salad dressings, and peanut butter. The date, which is provided by the manufacturer, tells you how long the product is likely to remain at its absolute best quality when unopened. It is not a safety date. Examine the product to gauge the quality after the date and discard foods that have developed an off odor, flavor, or appearance.
Expires on: The only place you’re likely to see this is on baby formula and some baby foods, which are the only food products the federal government regulates with regard to dating. Always use the product before this expiration date has passed for safety reasons.
Stamped Dates on Packages: Products like bagged salad greens, bread, and pre-cut vegetables often feature a date stamped on the package. This date is to help the store determine how long to display the product for sale. It can also help the purchaser know the time limit to purchase or use a product at its best quality
