Eleven on the controls provided AAF and six/twelve rats fed AAF moreover saccharin formulated palpable mammary and ear-duct tumours. Liver tumours had been noticed in both equally teams, but they were being smaller and fewer malignant while in the saccharin-fed animals.

Dams were exposed to 5% sodium saccharin [2500 mg/kg bw per day] in the eating plan starting four months before mating and were both killed in the course of late gestation or continued on procedure with the F1 technology right up until 22 days of age.
