There is no uniform or universally–accepted system used for food dating in the United States. In fact, product dating is generally not required by federal regulations (except for infant formula), and the FDA does not require "expired by," "use by" or "best before" dates on food products; such information is entirely at the discretion of the manufacturer. According to the FDA, a principle of U.S. food law is that foods in U.S. commerce must be wholesome and fit for consumption. An expiration date does not relieve a firm from this obligation. A product that is dangerous to consumers is subject to potential action by the FDA to remove it from commerce regardless of any date printed on a label.
