Vomitoxin , also deoxynivalenol (abbr. DON) - organic matter , trichothecene mycotoxin , a secondary metabolite produced by several types of micromycetes - microscopic mold fungi of the genus Fusarium ( Fusarium culmorum , Fusarium graminearum ). It is a contaminant . Highly toxic. Causes severe poisoning, accompanied by vomiting (from the English. Vomiting - vomiting ) and gastrointestinal disorders. It has an immunosuppressive effect [1] [2] .
