Linseed (Linum usitatissimum L), collected from kothi and gunny bag, had a total of 18 fungal species. Aspergillus spp were the more frequent and accounted for more than 40 % of the total count. The gunny bag storage system exhibited higher dominance of A flavus than occurred in the kothi system. Out of 251 isolates screened, 44 % were toxigenic and produced different components of alfatoxins in the range 105–3000 μg litre −1 . Of 105 samples extracted for the natural presence of alfatoxin, 46 had aflatoxin contamination. The concentration of alfatoxin B 1 in contaminated samples ranged from 120 to 810 μg kg −1 .
