Sažetak
To be able to properly estimate the exposure to mycotoxins, the two approaches can be used: the biomarker approach and the recalculation base on the mycotoxin occurrence data. Both approaches have its own advantages and drawbacks. There is more data and methods available for mycotoxin detection in raw materials (mainly cereals as the main source of mycotoxins), but for exposure assessment, additional data is needed. The consumption data is different for every individual, and approximations based on the big databases can be used. The other problem is the food preparation techniques, since most of the cereals are heavily processed before eaten, and there is big data gap compared to raw cereals data, and the mycotoxin reduction and/or modification during processing. On the other hand, usage of human biomarkers is usually limited due to low concentrations found, less available methods for detection, and different metabolites of original mycotoxins. Since most xenobiotics are metabolized to become more polar, and excreted via urine, it is most often used for mycotoxin biomarker studies. In Croatia, both approaches were tested. The urine biomarker screening of the 40 pregnant women revealed that they were exposed to low levels of ochratoxin A, but high levels of deoxynivalenol. On the other side, the CroMycoScreen project collected the data on the occurrence of both regulated and unregulated mycotoxins in cereals form all Croatian counties, and revealed that there were 128 different fungal, bacterial and plant metabolites present, including the emergent mycotoxins with special interest for EFSA. Out of all samples, 10 % were not suitable for human consumption, and 0.5 % were not suitable as animal feed. One of the project outcomes was to set up the mycotoxin heat map of Croatia, showing the more problematic regions for different mycotoxins, enabling the planning in the crop rotation policies and smart usage of contaminated cereals for biofuel production or as feed for more resistant animals.
