Modification of the rapid screening method for aflatoxin in corn for quantitative use.

A study was made to determine if the official AOAC method for screening of aflatoxin in corn could be modified for use as a quantitative method. Several different corn products were analyzed using the modified method, with an average savings of over 1 h/sample vs the CB method. Average recoveries for aflatoxin B1 were 94% for the low level spiked samples and 108% for the high level. Samples of corn and corn products containing naturally incurred aflatoxin were also analyzed with the modified method, and the results compared favorably with those obtained by the CB method.
