Abstract

Twenty-eight of 54 isolates of Aspergillus flavus grown on autoclaved agricultural commodities such as wheat, rice and corn were found to produce the mycotoxin cyclopiazonic acid. Eighteen of the A. flavus isolates produced aflatoxin, and fourteen isolates produced both cyclopiazonic acid and aflatoxin. A preliminary screening of some aflatoxin-contaminated corn samples revealed for the first time the natural occurrence of cyclopiazonic acid in agricultural commodities.
