Consumer Advice ​

Brown FK is a synthetic azo dye approved in the European Union (E154) only for smoked fish such as smoked herring and haddock, with strict usage limits. It is not permitted in China or the United States. Because its permitted uses are so limited, most consumers rarely encounter it, and it is considered safe within those limits.
