As part of its approval, the U.S. Food and Drug Administration (FDA) requires since 1986 that irradiated foods include labeling with either the statement "treated with radiation" or "treated by irradiation," along with the Radura. In the USA, irradiation labeling requirements apply only to foods sold in stores. For example, irradiated spices or fresh strawberries should be labeled. Irradiation labeling does not apply to restaurant foods or processed foods. (NOTE: The Radura symbol as compulsory under FDA-rule has a design slightly different from the Codex Alimentarius version; the 'leaves' being empty areas.)
