title: Betel-nuts as contaminated with a cancer producing fungus.
abstract: Betel nuts prematurely harvested and allowed to dry in heaps contain moisture which permits Aspergillus flavous to enter and spread over the central portions. Such betel - nuts consumed with betel leaves can cause cancer of the mouth since A. flavus is a carcinogen. Samples collected showed that the most betel - nuts were contaminated.
