【 摘 要 】

Climatic conditions prior to wheat harvest 2010 were favorable for thedevelopment of field molds. The most important wheat contamination thatshould be determined is the presence and frequency of grain lots infectedwith Fusarium. This paper presents the results of content of fusariouskernels found in samples collected from all wheat growing regions of Serbia.Investigations were performed according to the regulations which foreseesensory determination of content of infected kernels. Determined averagecontent of fusarious kernels was 6.01%, varying in range from 0% to 29.65 %.The obtained results, which exceeded the upper limits of permitted contentsdefined by national and EU regulations, pointed to the need for investigationof presence of Fusarium metabolic products, i.e. mycotoxins (zearalenone(ZEA) and deoxinivalenol (DON)) in wheat. Mycotoxin content was determined inaverage wheat samples and in wheat samples with increased content offusarious kernels. Direct enzymatic immunoaffinity test (ELISA) was appliedfor determination of mycotoxin content. Although high content of fusariouskernels characterizes wheat crop in 2010, the determined quantities of twoinvestigated mycotoxins did not exceed maximal permitted content.Consequences of unfavorable quantity and structure of total impurities inwheat crop in 2010 reflect decreased commercial and technological quality ofwheat and point out to the need of necessary wheat safety control.
