title: Lack of carcinogenicity of DDT in hamsters.
abstract: Syrian golden hamsters were fed for their lifespan a diet containing 0, 125, 250 and 500 parts per million (ppm) of ddt. The incidence of tumour bearing animals was 13% among control females and ranged between 11-20% in treated females. In control males 8% had tumours. The incidence of tumour bearing animals among treated males ranged between 17-28%. The incidence of adrenal cortex tumours showed a dose-related increase among the DDT-treated males. A liver-cell tumour and 2 liver hemangioendotheliomas were observed in 3 males treated with 250 ppm DDT. No liver-cell tumours were observed in the controls. No significant difference in tumour incidence was observed in treated versus control Syrian golden hamsters.
