The Food Safety Authority has issued a warning to Irish consumers over the illegal red food colourant, Sudan Red 1.
The authority says if people have products containing Sudan Red 1 they should either throw them out or return them to the shop where they purchased them.
The colourant is used to manufacture chilli powder.
A total of 39 food products currently available on the Irish market are implicated by the authority’s warning.
The list includes Cross & Blackwell's Worcestershire Sauce, and a number of products each from the Pot Noodles, Bird's Eye, Tesco, Heinz, Waitrose, Aunt Bessie's and Iceland food ranges.
The full list of products known to be on the Irish market is available here.

Sudan Red 1, an industrial dye, has been banned as a food colourant throughout Europe since 2003 due to its carcinogenic properties.
