Abstract

A survey of the mycoflora of poultry feeds and feed ingredients revealed a wide range of fungal genera and species, many of which are reported to be mycotoxigenic. Subculturing of randomly selected isolates from three of the most commonly occurring species confirmed their mycotoxin‐producing potential. On a brown‐rice substrate Aspergillus flavus Link produced on average 56 μg kg−1 aflatoxin B1. 53 μg kg−1 aflatoxin G‐1, and 336 μg g−1 cyclopiazonic acid. Similarly. subcultured Penicillium citrimum Thom produced 620 μg g−1 citrinin and Aspergillus tamarii Kita 13670 μg g−1 kojic acid. The need for a mycological/ chemical approach to mycotoxin monitoring is strongly indicated.
