Mycotoxin-producing fungi were isolated from contaminated grains of rice, p
ulses and oilseeds sold in the local markets of Calcutta for human consumpt
ion. It was found that aflatoxin B-1 was produced by Aspergillus flavus and
Aspergillus parasiticus, aflatoxin G(1) by A. flavus, ochratoxin by Asperg
illus ochraceous, sterigmatocystin by Aspergillus japonicus and citrinin by
Penicillium citrinum. Aflatoxin B-1 (333-10416 mu g/kg) was produced by As
pergillus spp. in rice, pulses and oilseeds.
