Canadian Grain Commission launches discussion on falling number and DON

News release

March 11, 2019                         Winnipeg          Canadian Grain Commission


As part of its grain grading modernization initiative, the Canadian Grain Commission invites grain sector stakeholders to provide input on whether falling number and deoxynivalenol (DON) should become official grain grading factors.

Currently, falling number and DON are not official grading factors in the statutory Canadian grading system for any type of crop. However, they increasingly play a critical role in grain contracts and the assessment and price that grain sector participants, including producers, receive for their grain. As well, advances in technology and analytical testing now provide the opportunity to test directly for these important characteristics using methods that are increasingly accessible to the sector.

The Canadian Grain Commission would like to hear from stakeholders whether they support the use of falling number and DON as grading factors within the Canadian grain grading system, and what the impacts would be if these changes were implemented.


A full discussion document is available on the Canadian Grain Commission’s website. Interested stakeholders are invited to provide their input in between March 11, 2019 and May 10, 2019.


We invite all sector stakeholders to join the conversation on whether to incorporate more analytical testing into the grain grading system, with a view to maintaining the standard of excellence for Canadian grain in the modern marketplace.”

Quick facts

  • The Canadian Grain Commission is committed to working with its stakeholders to review and modernize the grading system so that it continues to reflect the realities of the evolving grain sector.

  • The falling number value is an internationally standardized method for quantifying the extent of sprout damage in wheat.

  • Deoxynivalenol (DON), also called vomitoxin, is a mycotoxin produced by some species of Fusarium, a fungus that infects wheat, barley, oats and corn. DON is toxic to both humans and animals.
