What is the current tolerance for insects in stored grain?
Canadian law currently adheres to a “zero-tolerance” ideal. This means that even one insect found in a sample of stored grain is grounds for refusal. Grains that are infested must be controlled before delivery will be accepted. For Saskatchewan, if fumigation is the chosen method, it must be performed by persons holding a valid fumigation license.
