Natural occurrence of trichothecenes on lodged and water-damaged domestic rice in Japan.
In 1998, a typhoon struck before rice harvesting in Japan, and the unpolished rice was found to be stained brown. Samples were collected and analyzed for the presence of trichothecenes using GC/MS. The mycotoxins deoxynivalenol (DON), fusarenon-X (Fus.-X) and nivalenol (NIV) were detected and confirmed with GC/MS. The quantity of trichothecenes was determined using GC-ECD. To our knowledge, this is the first report of the presence of the trichothecene Fus.-X in rice.
