In terms of both quality and safety, expiration dates are of great importance, especially for products that are less shelf-stable in nature.

Greco walks us through a variety of scenarios with a common household product with a near-future expiration date, milk, where both storage and transportation variables can affect its condition, even the expiration date on the package. Even after the due date is printed. “If that milk was dropped off at the grocery store by a distributor, and it sat in the back of the fridge for 20 or 30 minutes, you might have a different profile,” he says. “If you buy that milk in South Florida, where it's 100 degrees, and you drive 30 minutes home, that's going to affect the quality as well.”

Expiration dates may also be printed with different languages, which create different concerns and may speak more to quality issues than safety. According to USDA Food Safety and Inspection ServiceThe meanings behind the various labels are:

  • Oh “Best if used by/before” date It tells when a product will be of the best taste or quality. This is not a purchase or security date.
  • Oh “by selling” The date tells the store how long to display the product for sale for inventory management. This is not a security date.
  • Oh “through use” The date is the last date that the product is recommended for use while still being of high quality. This is not a safety date (except when used on infant formula).
  • Oh “Frozen Through” The date indicates when a product should be frozen to maintain the best quality. This is not a purchase or security date.

These phrases can be helpful guidelines for consumers, but it's important to note that, except for infant formula, expiration dates are not required by federal law. As indicated above, none of these refer to the issue of safety where consumption is concerned. In short, you have to rely on your senses anyway, including common sense, to determine if a food is safe to consume.

“I think a lot of consumers have a hard and fast rule when it comes to expiration dates, thinking if it's the 28th or 29th, and something's on the 27th,” Greco says. It's expired, so they must throw it away,” Greco says, but that's not always, or even usually, the case. “You should at least smell it, and maybe taste it, and it can still be good,” he says.

On the other hand, it's an important habit to get into anyway, because you may suspect something has changed before the expiration date. Given a variety of transportation and storage scenarios, the expiration date may be meaningless, and as noted above, is not reflective of any federal regulations.

Even the USDA recommends this practice: “The quality of products with a perishable date may be impaired; however, such products may still be safe if handled properly. Consumers should determine To do this, the quality of the product should be evaluated before use to see if the product shows signs of deterioration.” You can handle food properly by putting it away as soon as you get home, knowing where it is. Your refrigerator has the coldest zones.Keep different types of food separate, use proper storage containers, and don't overfill them to begin with.

Greco notes that our shopping habits also likely play a role in throwing away non-perishable food. “Part of food waste is the lack of frequency of shopping at the store,” he says. When buying in bulk To save money on certain products, planning a menu or trying to stock up for weeks or months at a time instead of a few days can result in having more food on hand than is actually needed.
