This mycotoxin occurs predominantly in grains such as wheat, barley, oats, rye, and corn, and less often in rice, sorghum, and triticale.

[1] Furthermore, deoxynivalenol contents are significantly affected by the susceptibility of cultivars towards Fusarium species, previous crop, tillage practices, and fungicide use.

Reduced levels of serotonin are believed to be responsible for the anorexic effects of DON and other trichothecenes.

[5] When compared to other trichothecene mycotoxins which can form in grains and forages, vomitoxin is relatively mild.

Reduced feed intake, with its accompanying decrease in performance, is the only symptom of vomitoxin toxicity livestock producers will likely encounter.
