Occurrence of mycotoxins in cereal grains from organic farming after a long storage time

Abstract
Mycotoxin contamination of food and feed is a big problem, also with regard to cereal products from organic farming. For that reason screening of mycotoxins occurrence in cereal grains from organic farming after prolonged storage was performed. The work presents monitoring of the contamination of organic spring wheat, spelt, oat, rye and spring barley harvested in 2017, by the most important mycotoxins: deoxynivalenol (DON), zearalenone (ZEA), ochratoxin A (OTA), sum of aflatoxins (AFL) and the sum of T-2 and HT-2 toxins after nine months of grain storage in different storage systems. Content of mycotoxins was defined by enzyme-linked immunosorbent assay ELISA. Concentration of mycotoxins was very diverse and high in relation to OTA in spring barley and rye and in relation to Fusarium toxins (DON, ZEA, T-2/H-T2) despite low moisture of the grains (below 15%). Among analyzed cereals samples, rye was the grain that was the most frequently contaminated with all kinds of mycotoxins.
