Abstract
The production of total aflatoxin (B1, B2, M1 and M2) in ten tropical foodstuffs (with and without zinc enrichment) inoculated with Aspergillus flavus NRRL 3251 was examined to determine the effect of zinc on aflatoxigenic potential. Aflatoxin production was not linearly correlated with zinc levels of the food substrates. The data presented indicate that optimal zinc requirement for maximal aflatoxin production was substrate specific.
