Fusarium species and 8-keto-trichothecene mycotoxins in Manitoba barley.

Fusarium head blight, induced primarily by Fusarium graminearum, resulted in widespread damage to the Manitoba barley crops of 1993 and 1994, with contamination by DON and other 8-keto-trichothecenes.  A commercial enzyme immunoassay for DON gave results that correlated well with GC-MS methods and afforded a rapid and convenient method for screening.  In barley samples from 1994, DON, 15-acetylDON, 3-acetylDON and 3, 15- diacetylDON were detected in the approximate ratio of 47:4:1:1.  In view of the higher oral toxicities of 15-acetylDON and 3-acetylDON relative to DON, and the unknown oral toxicity of 3, 15-diacetylDON, GC-MS assays might be advisable in samples positive for FON from enzyme immunoassay screening.
