A highly selective and sensitive enzyme-linked immunosorbent assay (ELISA) for the determination of the synthetic dye Para red in foodstuffs has been developed by Ting Xu, from the China Agriculture University, and colleagues. Para red is a dye that is used in printing, and is prohibited in foodstuffs due to it being a potential genotoxic carcinogen. The assay was tested on real food, and was comparable to current methods which are more resource intensive.
