Vomitoxin contamination harms farms, feed, and grain mills by reducing productivity, compromising quality, and creating food safety risks. Vomitoxin testing is important in the field because Fusarium flourishes in soil. If it is not detected in the field, the contamination will prevail in storage and withstand basic food processing. Fusarium infections look different depending on the plant it infects. For barley, Fusarium appears as a brown discoloration at the base of the glumes. On wheat, it appears as a pink or reddish mold on the glumes and kernels. On corn, a pink or reddish mold appears on the tip of ...

Rapid tests for deoxynivalenol (a.k.a., DON and vomitoxin) from Neogen® can screen a wide variety of grain and grain product samples at 1 ppm, or provide fully quantitative results in the range of 25 to 250 ppb (high sensitivity test), or 0.25 to 5 ppm. Deoxynivalenol (DON) is most commonly produced by the pink mold Fusarium graminearum. DON, a member of the trichothecene family, is produced by fungi living on cereal commodities such as wheat, corn, barley and ensilages. The toxicological effects attributed to DON include: nausea (vomiting), feed refusal, gastroenteritis, diarrhea, immuno-suppression and blood disorders. Neogen provides several DON (...

Vomitoxin Field Test

Need for a field test for vomitoxin in wheat.  Farmer harvests wheat and hauls to elevator. Elevator can test for vomitoxin. If above a threshold, load is rejected. Farmer loses money in time and transport costs. If had a quick, reliable field test could blend loads or otherwise know that load will be accepted at the elevator.    reported Aug 3, 2019 by Jake P from IL
