Mettrum reportedly expands recall to all products sold between January 1 and March 21, 2016

Additional testing by Mettrum has found more cannabis with the unapproved pesticide myclobutanil on it

Mettrum has reportedly sent out emails to their registered clients informing them of an expansion of their Type III recall, which included Myclobutanil, a pesticide not approved for use on cannabis in Canada under the Pest Control Products Act. Mettrum is expanding the recall to include all products sold between January 1, 2016 and March 21, 2016.

Mettrum says they recently became aware of the Myclobutanil after additional testing following their first recall late last year, after using a 'plant wash' product that contained pyrethrin, an unapproved pesticide. The pyrethrin was not labeled as an ingredient on the product. About a month after that recall, Mettrum announced an expansion for an additional pesticide, myclobutanil. OrganiGram has issued a similar recall recently with a similar timeframe of product.

Dear Mettrum Client,

As part of our ongoing voluntary recall investigation and to further enhance our strict quality control, Mettrum has conducted additional testing on its products. As a result, Mettrum has recently become aware that some of its products contain small amounts of Myclobutanil, a pesticide not currently approved for use on cannabis under the Pest Control Products Act.

Rest assured, this material is not deemed to present a health risk. The fungicide Myclobutanil is used widely in Canada and around the world on food crops including lettuce, fresh fruit and berries.

Mettrum is committed to supplying the highest-quality and safest product to our clients at all times. In keeping with this commitment, and in full cooperation with Health Canada, Mettrum is extending its voluntary withdrawal of medical cannabis to include products that have been found to contain the substance. As a precautionary measure, Mettrum is also expanding the recall to include all products sold between January 1, 2016 and March 21, 2016. This is an extension to the process defined by Health Canada as a Type III recall: a situation in which the use of, or exposure to, a product is not likely to cause any adverse health consequences.

You are receiving this email because our records indicate that you may have received product that fits in the scope of this voluntary withdrawal. With your privacy and safety in mind, we encourage you to please login to Mettrum’s secure client portal here, for more specific information and next steps as to how to safely destroy any remaining product. We also invite you to contact us directly on our dedicated voluntary recall line at 1-866-661-2060 or by sending an email to should you have any further questions.

We apologize for any inconvenience that this may cause and would like to extend a discount of 20% on your next purchase with Mettrum in appreciation of your cooperation and continued support.

Yours in good health,

    "Yours in good health"??? That's a bit choking isn't it? Pun intended considering many of us smoked or vaped contaminated cannabis that we're supposed to believe is so hard to grow, we can't do it ourselves.

    You'd think they could come up with a less ironic end greeting!!
