Hazard classification:

Health Canada
Undeclared Substance
General Public
Identification number:


On June 2, 2017, Hydropothecary, a producer of cannabis for medical purposes located in Quebec, began a voluntary recall of nineteen lots of product under a Type III recall, in addition to fourteen lots of product under a Type III recall that was initiated on May 16, 2017. The products recalled include dried marijuana from plants that were grown between April 14, 2014 and September 16, 2016. The affected lot numbers are found below.


Following an unannounced inspection by Health Canada at the Hydropothecary site in March 2017 to conduct random sampling of cannabis products, test results of two leaf samples indicated the presence of myclobutanil at low level concentrations between 0.012 and 0.023 parts per million (ppm). Hydropothecary undertook further testing on various products at their site which indicated the presence of low levels of myclobutanil in dried marijuana and marijuana plants. As a result, on May 16, 2017, Hydropothecary initiated a voluntary recall for products that were sold between February 1, 2016 and May 1, 2017.

On June 2, 2017, Hydropothecary expanded the voluntary recall to include products sold between July 15, 2015 and March 24, 2017, following subsequent testing that identified lots containing low levels of myclobutanil.

A Type III recall refers to a situation in which the use of, or exposure to a product is not likely to cause any adverse health consequences.

Myclobutanil is not found in the seventeen pest control products that are authorized for use on cannabis plants under the Pest Control Products Act. Myclobutanil is found in pest control products that are approved for use in food production. All tested lots did not exceed any of the levels permitted in food production for myclobutanil.

Health Canada has not received any adverse reaction reports related to Hydropothecary’s products sold affected by the recall. Health Canada recommends that any individual affected by the recall immediately stop using the recalled product and to contact Hydropothecary at the following number 1-844-406-1852.
