Use-by date

Use-by dates suggest the peak quality of a product, and are not safety dates. According to the USDA, “With the exception of infant formula, if the date passes during home storage, a product should still be safe and wholesome if handled properly until spoilage is evident. Spoiled foods will develop an off-odor, flavor, or texture due to naturally occurring spoilage bacteria. If a food has developed such spoilage characteristics, it should not be eaten.”

Best if used by date

This label is strictly a quality date, suggesting when the product will have its best taste and texture.

Sell-by date

This label indicates to stores how long a product should remain on shelves, and products are often safe to consume well after their sell-by date passes. In fact, according to the Institute for Food Safety and Health at the Illinois Institute of Technology, “one-third of a product’s shelf-life remains after the sell-by date for the consumer to use at home.”
