<i>Fusarium</i>Mycotoxins (Fumonisins, Nivalenol, and Zearalenone) and Aflatoxins in Corn from Southeast Asia

Corn samples collected from the Philippines, Thailand, and Indonesia were surveyed for the natural occurrence of Fusarium mycotoxins (fumonisins, trichothecenes, and zearalenone) and aflatoxins. Fumonisins B1 and B2 were found in over 50% of corn samples in individual countries, and their co-occurrences with aflatoxins at the incidence of 48% were noted. In addition to these mycotoxins, a trichothecene, nivalenol, and an estrogen, zearalenone, both mycotoxins of Fusarium species, were detected in these Southeast Asian samples. This is the first report on the simultaneous occurrence of two carcinogenic mycotoxins, fumonisins and aflatoxins, together with Fusarium mycotoxins (nivalenol and zearlenone) in corn from Asian tropics.
