The Panel noted that Red 2G is extensively metabolised to aniline. The Panel noted that the current genotoxicity and carcinogenicity databases on Red 2G and its metabolite, aniline, are limited. However both genotoxic and carcinogenic effects have been observed in rodents treated with aniline. The Panel based its evaluation on the conclusions of the EU
