Postharvest incidence of aflatoxins in Linum usitatissimum seeds.

Linseed (L. usitatissimum), collected from kothi and gunny bags, was contaminated with a total of 15 fungal species. Aspergillus spp. were the most frequent and accounted for >40% of the total count, followed by Penicillium citrinum (24%) and Fusarium spp. (18%). The gunny bag storage system exhibited higher counts of A. flavus than occurred in the kothi system. Of 251 isolates screened, 44% were toxigenic and produced different aflatoxins in the range 105-3000 micro g/litre. Of 105 samples extracted for the natural presence of aflatoxin, 46 had aflatoxin contamination. The concn of aflatoxin B1 in contaminated samples ranged from 120 to 810 micro g/kg.
