Health Canada will begin randomly testing pot from licensed medical marijuana producers to ensure that unauthorized pesticides are not used in the growing process, after two growers were found to be using banned pesticides, the agency announced Wednesday.

The random inspections will check to ensure that licensed producers are sticking to the list of 13 approved pesticides for use on medical marijuana. The agency says producers caught using unauthorized pesticides will be required to recall their products, and corrective action will be taken.

The new measures come after products from two licensed growers were found to contain low levels of myclobutanil, bifenazate and pyrethrins, which are prohibited under the Pest Control Products Act and the Access to Cannabis for Medical Purposes Regulations. Corrective action was taken in both cases and Health Canada says it’s “satisfied” with the voluntary recalls carried out by the producers. [Read more at CTV News]
