The wet weather this past summer has resulted in a mould infestation affecting field corn in Ontario.
According to a report at CBC, farmers are seeing corn kernels decorated DON, which stands for Deoxynivalenol, a type of vomitoxin. The toxin is produced by a type of fungus, which infects a number of grains, including wheat and barley.
Great Lakes Grain Inc., which operates 25 grain elevators across the province, says levels are "spiking much higher" this year.
"In most years, most of the crops are very marketable with less than 3 ppm of vomitoxin in most years," General Manager Don Kabbes told CBC.
