"Organigram has said it does not know how the substance entered its crops but is working with Health Canada to find out more, noting it is a certified organic grower and does not use pesticides in its production processes."

sounds like bullshit. three hypotheses:

1) big growers stamping out little growers. this is what regulation means. but, at least it suggests they're serious.
2) it's meant to justify regulation. i don't care, really, i'd just like them to hurry the process up. if i get convinced that this was a cynical ploy, i'm going to raise hell. but, again, it suggests some level of seriousness.
3) feet dragging.

but, they're accusing a grower that does not use pesticides of having a banned pesticide, and that does not pass the smell test; something is happening.
