Abstract
The article presents the results of a survey of 26 production batches of rapeseed cake and meal for microscopic fungi and mycotoxin contamination. The indicator of the total number of fungi in most samples corresponded to the regulated norm of 5000 CFU/g, Penicillium spp., Aspergillus spp. prevailed in the composition of the mycobiota, Cladosporium spp., Scopulariopsis spp. were detected less often, and flour fungi and yeasts were found in small amounts. The presence of the anthraquinone toxin emodin in all samples was established by the method of indirect competitive enzyme immunoassay, alternariol, mycophenolic acid and ergoalkaloids were detected somewhat less frequently, in isolated cases – aflatoxin B1, cyclopiazonic acid and T-2 toxin. The prospects for further research and the need to assess the potential of toxin formation by sanitary-significant micromycetes are discussed.
