| Abstract: | During an investigation of the mycoflora on oilseed rape, the predominant fungal species present in 20 samples collected from Catalonia (Spain) wereAlternaria alternata (Fries) Keissler,Penicillium spp. andAspergillus flavus. None of the 20 samples analyzed presented contamination byAlternaria mycotoxins (tenuazonic acid, alternariol, alternariol methyl ether, altertoxin I and altertoxin II). Only aflatoxin B1 was detected in 1 of the 20 samples analyzed, with a concentration of 0.25 ppb. Of the 40Aspergillus flavus strains isolated from oilseed rape samples, only 3 revealed aflatoxigenic capacity. None of thePenicillium spp. isolated from oilseed rape samples revealed mycotoxigenic capacity (citreoviridin, griseofulvin, citrinin, patulin and penicillic acid). |
