title: The mycotoxin research in foodstuffs in the Czech Republic in the 90th Years.
abstract: Mycotoxins are naturally occurring secondary metabolites produced by several toxigenic microscopic fungi on a variety of crops, especially cereal grains and further foodstuffs. Series of experimental research projects on the determination of mycotoxins (aflatoxins, cyclopiazonic acid, ochratoxin A, patulin, deoxynivalenol, fumonisin B1, T-2 toxin, zearalenone, sterigmatocystin, alternaria toxins) in several foods were realized in the National Reference Centre for Microscopic Fungi and Mycotoxins in the 90(th) years. The aim of our work was an estimation of dietary exposure to mycotoxins and risk assessment. The method of a solid phase extraction (SPE), liquid - liquid extraction and immunoaffinity chromatography (f. e. R-Biopharm, VICAM) were used to elaborate for sample analyses of mycotoxins in our projects. The mycotoxins were detected most frequently by chromatographic methods (HPTLC, HPLC, GC) and immunochemical methods (ELISA). Average dietary exposure has been calculated by multiplying of concentration data for specific foods with their consumption rates per 1 kg of b. w. per day. The estimation of the dietary exposure dose of mycotoxins for the Czech population is presented.
