12 permitted food colours in use were screened for geno-toxicity. Mitotic gene conversion in Saccharomyces cerevisiae was used as the end-point. Each food colour was tested in stationary-phase as well as log-phase cells but without microsomal activation. These food colours did not cause any increase in mitotic gene conversion in diploid yeast BZ 34.
