title: Deoxynivalenol and 3-acetyldeoxynivalenol - mycotoxins associated with wheat head fusariosis in Poland.
abstract: Samples of wheat naturally infected in the field byFusarium culmorum (W.G.Sm.) Sacc. andFusarium graminearum Schwabe were analyzed for deoxynivalenol, 3-acetyldeoxynivalenol, and zearalenone. No zearalenone was detected at levels higher than 0.5mg/kg. Deoxynivalenol was present in 100% and 3-acetyldeoxynivalenol in 80% of the examined samples at levels of 0.21 to 30.4 mg/kg and 0.54 to 29.54 mg/kg, respectively. The mycotoxin levels in the chaff were 5 to 50 times higher than in the kernels. This is the first report on natural occurrence of 3-acetyldeoxynivalenol in wheat. This toxin, in addition to deoxynivalenol, was highly correlated with wheat head fusariosis. These findings suggest that more attention should be given to the occurrence of 3-acetyldeoxynivalenol in cereal grains during the growth as well as during storage.
