Long-term toxicity studies on Chocolate Brown HT in rats. 1978

F M Carpanini, and K R Butterworth, and I F Gaunt, and I S Kiss, and P Grasso, and S D Gangolli

Groups of 48 males and 48 female rats were given diets containing 0 (control), 500, 2000 or 10,000 ppm Chocolate Brown HT for 2 years. These treatments had no adverse effect on mortality, body-weight gain, food or water consumption, haematology, renal function, serum constituents, organ weight or histopathology. From the incidence of tumours observed in the control and test animals it is concluded that Chocolate Brown HT did not exert any carcinogenic effect and that the no-untoward-effect level was 10,000 ppm.
