Prevent treated seed contamination

Sept. 13, 2013 - Western Canadian grain producers are harvesting their crops, and some are planting winter wheat. Because producers may be handling seed and harvested grain at the same time, there is a risk that treated seed may contaminate harvested grain intended for delivery.

The Canadian Grain Commission reminds producers they can prevent treated seed contamination by following these precautions:

  • When possible, store treated seed in separate bins.
  • Clean all equipment and bins after seeding and before harvest.
  • Visually inspect equipment and bins for treated seed:
    • Before harvest
    • Before transferring grain between bins
    • Before transferring grain to a truck or railcar for delivery
Limits and restrictions in grain handling
Health Canada has set maximum residue limits for chemicals in Canadian grain. Any grain exceeding these limits can be condemned. This means that the grain cannot enter the food or feed system and is destroyed.

Under the Canada Grain Act, a licensed grain handling facility cannot receive grain that is contaminated and may refuse to accept delivery of any grain that is believed to be contaminated. As well, the Canada Grain Act prohibits delivery of grain that is contaminated.

If treated seed is found in a shipment at the terminal elevator, the shipment will be held until the Canadian Grain Commission completes a chemical analysis.

Any delays caused by treated seed can result in additional cost to grain handlers or producers. For example, if a producer car is contaminated, extra charges such as storage charges or costs related to potential contamination of other grain in the facility, resulting in loss of the grain's value, could be passed on to the producer.
