Malachite green is retained in catfish muscle longer (HL = 10 days) than is the parent molecule (HL = 2.8 days). The (oral, mouse) is 80 mg/kg. Rats fed malachite green experience "a dose-related increase in liver DNA adducts" along with lung adenomas. Leucomalachite green causes an "increase in the number and severity of changes".
