Sažetak
Fumonisins are mycotoxins produced by some strains of Fusarium moulds. They cause equine leukoencephalomalacia, pulmonary edema in swine and hepatic and kidney lesions in various laboratory animals. Fumonisins are frequently found as contaminants of corn in temperate climatic zone, but the knowledge about their occurrence in our country is scarce. 49 corn samples were collected during fall 2002. from 14 counties of Republic of Croatia. Samples were purified by means of immunoaffinity clean-up procedure and the concentration of fumonisin B1 (FB1) and fumonisin B2 (FB2) were determined by HPLC method with fluorescent detection. Limit of detection for both mycotoxins was 10 mg/kg. Reproducibility of the method expressed as Relative Standard Deviation (RSD) was below 10 %. FB1 was found in all analyzed samples of corn in the range of 142-1378 mg/kg, and the mean concentration was 460 mg/kg. Most of samples (45 %) contained between 200 and 400 mg B1/kg. FB2 was found in 3 samples (6 %), and the concentrations were 68, 109 and 3084 mg/kg. Although the year when samples were collected was extremely wet and the frequency of finding, as well as the concentration of mycotoxins is certainly not common, our results indicate that fumonisins are very frequent contaminants of corn in our country.
