A survey was undertaken to determine total fumonisins (FUMs) and deoxynivalenol (DON) in wheat and maize. Out of 75 wheat samples, 50.7% contained FUMs in the span from 27 to 614 ng/g, while 65.3% contained DON in the span from 64 to 1,604 ng/g. Out of 24 maize samples, contents of FUMs in one and of DON in three samples were above the maximal limit. This is the one of rare reports of the natural co-occurrence of FUMs and DON in wheat and maize, and the first report of their correlation in different wheat cultivars.
