"The legal status of Irn-Bru in America is unclear. Several American companies import Irn-Bru, yet it is currently listed as a banned substance by the U.S. Food and Drug Administration. The FDA website[3] lists Irn-Bru and Diet Irn-Bru as containing the banned carcinogenic colouring Ponceau 4R, and Sunset Yellow FCF, which the FDA has to approve on a per-batch basis[4]. One importer, Great Scots International [5], modifies the drink to conform to FDA requirements."
