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".

During the experiment, rats were fed up to 543 ppm of leucomalachite green,
