Abstract

The studies to determine the level of filamentous fungi and mycotoxins were carried out in samples of grain and grain dust during threshing of cereals by a combine harvester. High concentration of fungi was noted in grain and grain dust samples ,it ranged from 5.0 to 520.0 cfu/g * 10³ and from 275.0 to 2825.0 cfu/g * 10³, respectively Allergizing and toxigenic fungi of Alternaria, Geotrichum, Cladosporium, Penicillium, Aspergillus and Fusarium species were observed in the study samples of grain and grain dust. In the samples of wheat grain,mycotoxins were also noted: moniliformin (MON), deoxynivalenol (DON) and ochratoxin A (OTA); their concentrations ranged from 0.025 to 0.088 ľg/g; 0.015-0.068 ľg/g; and from 0.0004 to 0.0008 ľg/g, respectively. The level of mycotoxins in the grain dust samples was within the range of 0.025-0.149 ľg/g - MON; 0.015-0.215 ľg/g - DON; 0.015ś0.360 ľg/g - NIV; and 0.0004ś0.0012 ľg/g - OTA. A significant correlation was observed betweenthe occurrence of fungi of Fusarium species and the concentration of pathologic mycotoxins. The results confirm a considerable occupational risk among farmers engaged in grain threshing due to inhalation of pathogenic species of filamentous fungiand mycotoxins.
