Lab Tests Reveals Medical Cannabis Sold with Mold in Phoenix, Arizona

The Arizona Medical Marijuana Act (AMMA), or Proposition 203, passed with the most narrow of margins in 2010. Since then, the medical cannabis program in the Southwestern state has developed rapidly. Patient cards can cost upwards of $300 and dispensary agents input every hundredth of a gram purchased into a state database. Despite these rigid seed-to-sale tracking systems, there are currently no laws in place that a cultivation must test their medical cannabis flowers before they go to market. This may change, however, after a recent report by Derek Staahl uncovered a severe mold problem at Encanto Green Cross in Phoenix.

This Fall, Arizona Family toured their facility in Phoenix. After their report aired former employees reached out claiming that the team missed something. Former employees of the cultivation and dispensary came out about issues with mold on cannabis that they had seen at the state-licensed cultivation. Two employees in particular provided emails and testimony about mold present both at the multiple sites in the cultivation and in the actual flowers that they were trimming. This inspired the investigative team to jump into action.

While high amounts of mold shouldn’t be burnt and inhaled by anyone, it is especially important that patients with autoimmune diseases or otherwise compromised immune systems don’t inhale these contaminants. Arizona Family, sponsored by CBS 5, sent a licensed Arizona Medical Marijuana (AZMMJ) patient out to purchase four separate samples of cannabis flowers from Encanto. The samples were then monitored and delivered to Delta Verde Laboratory for yeast and mold testing.

What they found was concerning, three out of the four tests exceeded mold threshold standards of 10,000 colony-forming units per gram. Though there is still no “universally accepted standard” for how much mold is safe for a patient, these are the standards set in recreational cannabis states like Colorado and Washington. When the investigative news team showed Encanto managing partner Bill Brothers the results, he simply dismissed them. He also cited that Encanto Green Cross had no ethical or legal obligation to pull any of the product.

Brothers deflected the test results stating that there isn’t any way to know if the results are valid. They also provided results from visual inspection tests that the dispensary ordered from C4 Laboratories. However, the visual inspection, completed using a microscope, is not a reliable one for detecting mold at actionable levels. Brothers also stated that they do their own in-house testing of flower alongside the results from the independent testing lab. Despite Brothers’ confidence in their product, another cannabis testing lab did find issues with mold in flower sold in their dispensary after completing a full microbial analysis.

Come to a conclusion on your own, read the full report by Derek Staahl here on the Arizona Family website. http://www.azfamily.com/story/37021592/lab-tests-find-mold-on-medical-marijuana-sold-in-phoenix-it-should-be-pulled-off-the-shelf

  • This article contains a serious error, or is highly misleading at best. The news team lead by Derek Staahl brought the Encanto Green Cross samples to Delta Verde Laboratory for yeast & mold testing. They were NOT, as far as I can tell, ever sent to Desert Valley Testing for that test. They may have been sent to Desert Valley Testing for moisture testing, but that would have nothing to do with the news story. We maintain a cordial professional relationship with our competitors at Desert Valley, but Terpenes & Testing needs to give credit where credit is due.

    • This is a gross oversite to say the least. Our deepest apologies, James. We have added an edit at the top of the post, corrected the error and made sure to link to Delta Verde Laboratory. Thank you for your diligent work in the Arizona market, and thank you for calling this error to our attention.
