The authors studied the mutagenic action of the food dyes, tartrazine (both Soviet and imported) and indigocarmine in a microbial model and in warm-blooded animals (linear mice). Determined the toxicity and mutagenic action of the dyes on E. coli, strain K-12, carried out chromosomal analysis of the bone marrow, examined the dominant lethals in CBA X C57BL/6 mice. The recommended daily dose amounts to 400 mg/kg for tartrazine and to 50 mg/kg for indigocarmine with regard to the safety factor equal to 100. The data derived as a result of studying the mutagenic activity of tartrazine manufactured in the USSR and CSSR and indigocarmine paste in 3 experimental models allow the conclusion to be made that the doses of these dyes applied in food industry are fairly safe.
