Pre-rolls and marijuana flower sold at roughly 40 Colorado dispensaries are being recalled after testing found the products were contaminated with pesticides, state officials said Monday.

Three products from Verv LLC, which does business as Dadirri, had pesticide levels above the limits allowed by state regulations, officials with the Marijuana Enforcement Division said in a health and safety advisory.

The batches had initially passed lab tests but were later subject to additional testing, state officials said.

Those tests found the batches contained the pesticide chlorfenapyr, Marijuana Enforcement Division spokesperson Heather Draper said in a statement. Draper declined to say how many contaminated products were distributed and when the problem was discovered, citing the ongoing investigation and confidentiality rules for the state’s inventory tracking system.

Dadirri worked with state officials to issue a voluntary recall for the products, which include Caviar Creamsicle and Caviar Sherbert Pie flower and Strawberries N Cream pre-rolls sold between April 24 and June 5 in batches 65088, 65090 and 65324.

Anyone who purchased one of those products should return it to the store where they bought it, and anyone who got sick after consuming the products should seek medical attention and report their reaction to the Marijuana Enforcement Division, state officials said.

The contaminated THC distillate was purchased from another company before it was infused into Dadirri’s products, company CEO Ashley Schriener told The Denver Post.

The distillate had passed lab safety tests done by the original producer as well as those ordered by Dadirri, Schriener said.

“This is not anything we’ve had to deal with before. It was out of our control and we acted as quickly as we could,” Schriener said.

Dadirri had the products tested again after hearing from state officials, and they still passed safety tests. Schriener declined to say what lab the company used for testing.

The company prides itself on buying “the best of the best” inputs and focusing on cleanliness, she added.

“The reason why we have stood the test of time is quality, and we’re going to move past this,” she said.
