Freshly harvested inshell peanuts with moisture content ranging from 12.8-16.9% were threshed and sacked in interlaced polystyrene bags. Stacked bags were fumigated with phosphine during seven days. The initial dose of phosphine was 3g/m3 followed by an equal dose 24hr later. One month after fumigation, the percentage of grains infected with A. flavus/A. parasiticus in the bottom and the middle layers of the untreated stack was approximately 8 and 3 times higher than the values for the corresponding layers of the treated stack. No aflatoxins were found in the bottom and middle layers of the fumigated stack but were detected in the corresponding layers of the untreated stack. Aflatoxins were detected on the top layers of both treated and untreated stacks.
