Abstract
Aflatoxin, a metabolic product of Aspergillus flavus and A, parasiticus, is one of the strongest carcinogenic compounds, and it is found in several kinds of foods and foodstuffs. Most countries set limits on aflatoxins, and the regulation level in Japan is 10 ppb for aflatoxin B1. In our laboratory, aflatoxins in foods and foodstuffs have been tested since 1971, when aflatoxin was first found in peanut cream in Japan. This report summarizes the data on aflatoxin contamination in commercial foods and foodstuffs in Tokyo for 15 years during the period of 1982-1996.
