Methyl orange has given no evidence of carcinogenic potential in limited oral and injection studies in the rat. It was mutagenic in Ames bacterial tests following metabolic activation, but has mainly given negative results in genotoxic assays in mammalian cells in culture and did not induce chromosomal effects in mice treated by intraperitoneal injection. A high acute oral toxicity was demonstrated in rats. There was some evidence of skin sensitization in man.
