What is the difference between “best by” and “use by” dates on food labels?
The “best by” and “use by” dates on food labels are often misunderstood, leading to confusion and unnecessary food waste. The “best by” date refers to the manufacturer’s recommendation for the optimal quality and flavor of the product. It is not a safety date, but rather a guideline for consumers to determine the product’s peak freshness and taste. Foods that are past their “best by” date may still be safe to consume, but their quality may have decreased.
In contrast, the “use by” date is a safety date that indicates the last day of the product’s guaranteed safety. Foods that are past their “use by” date may pose a risk to consumer health, as they may have spoiled or developed harmful microorganisms. It’s essential to follow proper storage and handling practices to ensure food safety, even if the product is within its “use by” date. Consumers should always check the food for visible signs of spoilage, such as unusual odors, slimy texture, or mold growth, before consuming it.
