Sažetak
Mycotoxins are toxic secondary metabolites produced by fungi toxic for humans and animals. They are generally considered to be unavoidable contaminants of food for humans and animals and pose a major problem worldwide. Environmental conditions conducive to mycotoxin production are humidity and temperature, oxygen concentration, physical damage, and the presence of mold spores. It is assumed that the increase in the average temperature on Earth could lead to the migration of mycotoxigenic fungi from tropical and subtropical areas where high temperatures and humid conditions prevail towards more northern areas with temperate climates. In the project “Food production of biocomposites and cereals in a circular economy”, the occurrence of conidia of afla and ochratoxigenic fungi during threeyear in the experimental field in Osijek will be monitored. The occurrence of mycotoxigenic airborne molds in maize, wheat, and barley plantations, as well as in maize cobs will be analyzed. Preliminary results showed the presence of both aflatoxigenic and ochratoxigenic fungi in the field. About 10% of conidia isolated from the air belong to afla or ochratoxigenic species. The presence of these species was confirmed on swabs taken from damaged and contaminated maize cobs in the pre-harvest period. Analysis of the presence of aflatoxins and ochratoxin A in the harvested cereals is in the progress. The risk of contamination is present and the measures for prevention and control of aflatoxins and ochratoxin A should be applied.
