Abstract

Fifty Penicillium isolates from 90 corn samples were identified to
species following Pitt's method; the 12 identified species belong
in the four Penicillium subdivisions. In 72 of the samples the
contamination levels were below 16%, however, in 10 of them the
contamination levels reached 32.7% . Among the species identified
some are considered as storage species, others are field species,
and others yet belong to the non assigned category accordingly to
Mislivec and Tuite. All the species identified are reported to
produce mycotoxins, whether in nature or in the lab, and 10 of them
produce 0ne or more of the Penicillium mycotoxins isolated from
naturally contaminated corn. In this work, mycotoxins were not
determined, however, the implications of their presence in corn are
discussed.
