Consumer confusion about food labeling leads to significant waste. Many people mistakenly believe that dates on packaging, such as "best by" or "sell by," signify when food becomes unsafe to eat. In reality, these labels primarily address the quality rather than the safety of products. According to experts, this misunderstanding contributes to a substantial portion of food waste in the United States. The U.S. Department of Agriculture estimates that 30% to 40% of the nation's food supply ends up wasted, partly due to misinterpretation of these labels.

Understanding different types of labels can help reduce unnecessary waste. For instance, "use by" dates are intended to inform consumers about when a product will be at its peak quality. However, consuming food slightly past this date does not automatically pose a health risk; it may simply affect texture or taste. Similarly, "sell by" dates guide retailers on how long to display items but do not indicate whether the food is safe for consumption. Canned goods, when stored properly, remain safe even after the "sell by" date. Only infant formula is legally required to carry an expiration date in the U.S., ensuring its nutritional value and safety.

Consumers should rely on clear indicators to determine if food has gone bad. Signs like foul odors, sliminess, or mold are definite reasons to discard food. Bulging or dented cans can also signal potential contamination and should be thrown away. While freezer burn doesn't compromise safety, it can alter the taste and texture of frozen items. By educating themselves on proper food storage and label meanings, consumers can make more informed decisions, reducing both waste and anxiety about food safety.
