Every year, countless people throw away perfectly good food because they misunderstand the dates printed on packaging. Many assume that “Best By” or “Best Before” means the food is unsafe after that date, but in most cases, that’s not true. These dates are usually indicators of quality—not safety. A “Best By” or “Best Before” date simply tells you when the product is expected to taste its best. For example, a can of beans labeled “Best By June 2024” will likely still be safe to eat after that date, although the flavor or texture might not be at its absolute peak.
It’s important to know the difference between date labels. While “Best By,” “Best Before,” and even “Sell By” dates are mainly about freshness and quality, actual expiration dates (often written as “Exp.”) are the ones that indicate when a product may no longer be safe to consume. However, many canned and shelf-stable foods don’t even have a true expiration date. In most cases, as long as the can is in good condition—meaning there are no signs of bulging, leaking, severe dents, or rust—it is likely still safe to eat. Using your senses is key: if the food looks normal, smells fine, and tastes as expected, it’s probably still good.
Canned foods, especially when stored in a cool, dry place, can remain safe for months or even years past their “Best Before” dates. The real danger comes from damaged packaging, which can allow bacteria to grow. A swollen or leaking can, an unusual odor, or changes in color or texture are clear signs that the food should be discarded, regardless of the printed date.
Manufacturers include these dates primarily to guarantee the best taste and quality and to protect their brand reputation. Unfortunately, misunderstanding these labels leads to massive food waste. In fact, a large percentage of global food waste comes from consumers throwing away items that are still edible simply because the date has passed.
Understanding how to read these labels correctly can help you save money, reduce waste, and make more informed decisions about the food you consume. Before throwing away a can or package just because the “Best By” date has passed, take a moment to check its condition and use your judgment. A simple shift in perception can make a big difference—for your wallet and for the planet.
