This objective method of measurement has been used in terminal elevators for many years and is considered much more reliable. Seguin said that it is extremely important that samples be properly cleaned before they are graded. If the dockage is not removed from a sample, the amount of ergot present can be exaggerated. Seguin said the CGC has been in contact with the Western Grain Elevator Association to advise them of the potential for grading errors, and that the WGEA has agreed to advise member companies of the issue. Ergot is a disease of cereals caused by the fungus Claviceps purpurea.
Rye is the most susceptible, followed by triticale, durum wheat, bread wheat, barley and oats.
The fungus infects the head, replacing the seed with a hard, dark purplish fungal structure called a sclerotium or ergot body. Under existing grain and food safety standards, ergot does not pose a threat to human health. Feeding recommendations advise a maximum of 0.1 per cent for animal feeds. Feeding and health problems could develop in animals fed higher levels of ergot. To get a binding decision on grade and dockage, producers must Get an elevator receipt from the elevator operator for the grain delivered.
