Pesticides Lead to Biggest Marijuana Recall Yet in Colorado Nearly 100K packages of edibles present threat to public health By Michael Harthorne, Newser Staff Posted Dec 31, 2015 10:30 AM CST 29 comments Comments (Shutterstock) (Newser) – It was a dark day in Denver for edibles and the people who love them. More than 99,500 packages of Mountain High Suckers—marijuana-infused candy—were recalled on Wednesday, the Cannabist reports. It was Denver's largest recall of marijuana or marijuana products yet and the 15th such recall in 16 weeks. Back in November, Colorado's Gov. John Hickenlooper ordered the destruction of any marijuana treated with unapproved pesticides or any product made with that marijuana. According to the Cannabist, Mountain High Suckers' products tested positive for imidacloprid and myclobutanil, pesticides Hickenlooper has called a "threat to the public safety" and that the state has banned for use on marijuana plants. Mountain High Suckers apologized to its customers on Facebook. "We decided to take a proactive step and submit samples of all of our products for pesticide testing so we can help make sure that our products are safe," the company states. "Going forward, we will be voluntarily submitting every concentrate batch we make for full pesticide screening before we make products." Because marijuana remains illegal federally, the EPA has yet to actually rule on what pesticides are safe for use on cannabis crops.
