The total number of molds in cakes ranged up to 9.0 ´ 102 CFU/g. The highest number of molds was isolated on Dichloran 18% Glycerol Agar (DG18), and the lowest on Malt Yeast Extract 50% Glucose Agar (MY50G). Mycopopulation of cakes composed of species of genera Acremonium, Alternaria, Aspergillus, Cladosporium, Eurotium, Mucor, Phialophora, Penicillium, Fusarium and Ulocladium. Dominant species were A. niger, P. aurantiogriseum, P. brevicompactum, P. hirsutum, F. proliferatum and A. alternata. The most common potential producers were those of ochratoxin A (50.50%). The potential producers of fumonisins were present with 7.75%, moniliformin with 6.5% and sterigmatocystin with 0.75%. Potential producers of Alternaria toxins amounted to 4.5%. Aflatoxigenic molds were not isolated from the tested samples. Mycotoxicological analysis of the cakes did not determine the presence of aflatoxin, sterigmatocystin, ochratoxin A and zearalenone.
