According to the USDA, "sell-by", "use-by", "freeze-by", and "best if used by/before" dates are all indicators of quality, not safety. Except for infant formula, nothing is required to be dated by federal regulations, and an item being past its date does not necessarily imply spoilage, just a loss of quality.

You may want to check with your state and local governments to see if there are any more specific rules that would apply in your location.
