Date Labeling Confusion and Food Waste

Date labeling on food and drink products can be confusing, leading to significant food waste. Here, we clarify the issue and offer solutions. The different types of expiration dates, such as “use by” and “sell by,” can create confusion among consumers, who often mistake them for safety indicators rather than quality indicators. This misunderstanding often results in perfectly good food being discarded unnecessarily.

In an effort to reduce this confusion, the Food and Drug Administration (FDA) is working to standardize the use of the phrase “best if used by” to indicate the quality of the product. This phrase is generally used for non-perishable items, and it suggests that the food may not be at its peak freshness beyond that date. However, it does not mean that the food is unsafe to consume. The FDA advises consumers to rely on their senses and use their judgment to determine if a product is still suitable for consumption after the date listed.

By understanding the different types of date labels and their meaning, consumers can make more informed decisions about the food they consume. It is estimated that confusion over date labeling contributes to about 20% of food waste in the United States. By educating consumers and providing clearer date labeling guidelines, we can help reduce food waste and ensure that perfectly good food is not needlessly discarded.
