Deoxynivalenol, also known as DON or vomitoxin, has been found in some U.S. corn harvested this fall, causing headaches for growers and livestock producers and driving ethanol plants and grain elevators to scrutinize grain deliveries.
Reutersreports the latest mycotoxin situation isanother hit to global grain suppliesthat have sunk to the lowest in a decade since Russia invaded Ukraine.Droughthas also impacted U.S. and European crop.
What is deoxynivalenol?
Deoxynivalenol, known as DON or vomitoxin, is one of the mycotoxins most commonly produced by the fungus Fusarium graminearum.
制成的饲料颗粒污染的集中注意力d levels of DON can sicken livestock and lead to low weight gain, particularly among hogs.
Grain buyers can reject cargoes or fine farmers for shipments that contain it.
When harvest is slowed or delayed due to wet weather, the fungus can surface.
Reports of DON in corn
Early signs of the toxin are emerging in Ohio, according to a weekly report from theUSDA.
Reportsnote grain buyers in eastern Indiana are also starting to more rigorously test corn deliveries for vomitoxin.
TheMonday Mycotoxin and Crop Reportfrom Neogen this week noted DON in corn in Alabama and Ohio.
DON and DDGS
Deoxynivalenol can also caused issues for ethanol producers who sell the byproduct distillers dried grains (DDGS) for animal feed.
On its website,POET, notes it is testing for vomitoxin in grain being delivered to its plants in Fostoria, Leipsic and Marion, Ohio, and Portland, Indiana.
