Abstract
One hundred and forty-eight isolates of
Aspergillus flavus
and
A. parasiticus
were isolated from 5,608 pecans obtained from Chicago and Georgia markets. The percentage of internal contamination by these species was 7.3% in the Chicago market pecans and 1.7% in those from markets in Georgia. Of the 148 isolates, 93% of the
A. parasiticus
, but only 54% of the
A. flavus
, were capable of producing aflatoxin. Overall, 57% of the isolates were potentially aflatoxigenic.
A. parasiticus
isolates generally produced a greater amount of aflatoxins than
A. flavus
.
