Abstract:
Climate conditions in Serbia in the 2012 production year were favorable for fungal growth and mycotoxins production. The presence of fumonisins and aflatoxins in diverse corn-based food was examined using ELISA methods. The applied methods are rapid; demonstrate satisfactory repeatability and recovery rates 99% and 101% for total fumonisins and aflatoxins, respectively. Analysis of samples from 2012 revealed fumonisin contamination in all investigated samples, whereas aflatoxin contamination was detected in 55% of samples. The content of fumonisins did not exceed the maximum permitted level prescribed by the relevant Serbian, i.e., EU Regulation, whereas 3 samples were declared unacceptable due to increased aflatoxin content. High linear correlation coefficient (r = 0.947; p < 0.005) between fumonisin and aflatoxin contents in maize products was obtained. The results of the analysis of food for human nutrition strongly suggest the need for such monitoring and control.
