  • Title: Production of aflatoxins B1 and G1 by Aspergillus flavus and Aspergillus parasiticus isolated from market pecans.
    Author: Koehler PE, Hanlin RT, Beraha L.
    Journal: Appl Microbiol; 1975 Oct; 30(4):581-3. PubMed ID: 811163.
    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.
