Sažetak
Data published insofar have shown that the presence of mycotoxins as frequent contaminants of different foodstuffs greatly varies dependent on many parameters of influence, such as the type of product, weather conditions, cultivation practices, and others. However, contradictory results have been reported regarding mycotoxins and the safety of organic and non-organic food products. The aim of this study was to investigate the co-occurrence of the most representative Fusarium mycotoxins such as zearalenone (ZEN), deoxynivalenol (DON) and fumonisins (FUM) in different organic cereal-based products (n = 85), produced from maize, wheat, oats and barley, and available on the Croatian market. ELISA methods validation showed the mean recovery rates to range from 88.3% to 101.2%, with the intermediate precision of 82.4% to 99.4% and variation coefficients (CV) of 5.4%-7.5% and 7.2%-11.4%, respectively. Maize by-products proved to be the most contaminated cereal products, with DON as the most represented Fusarium mycotoxin (32.8%) followed by FUM (24.5%) and ZEA (16.1%). Huge variations in mycotoxins concentrations were observed for all the cereal products, with the highest mean levels of 175.6±112.5 μg/kg for DON, 164.3±103.6 μg/kg for FUM and 32.8±28.4 μg/kg for ZEN determined in maize meal. Although in some samples the level of mycotoxins identified was higher than the maximum prescribed by legislation, based on the mean concentrations established in all cereal-based products, as well as given that the exposure assessment resulted in low percentages of the tolerable daily intake (TDI) with the maximum of 7.3% determined for ZEN, the investigated Fusarium mycotoxins found in organically produced cereal products do not pose as a human health hazard.
