Deoxynivalenol (DON, also known as Vomitoxin) is a sesquiterpene compound found in Fusarium graminearum (roseum), F. culmorum, and other species. As one of the most common mycotoxins, DON often occurs in many plant products, particularly in cereal crops such as wheat, corn, barley, oats and rice.

In higher levels and more advanced stages of contamination, the symptoms linked to vomitoxin are much more severe and include abdominal pain, dizziness, headache, throat irritation, nausea, vomiting, diarrhea and blood loss with stools. In animals DON contaminated feed has led to feed refusal, and vomiting or diarrhea leading to growth depression. DON testing provides an important preventative tool for keeping production animals healthy and productive.
