Colorado cannabis regulators and an outdoor grower in Walsenburg have yanked dozens of recreational flower products off shelves after state testing turned up banned mold and elevated yeast. The voluntary recall, announced Friday, covers a product the state says was sold at 31 dispensaries across Colorado, most of them clustered in the Denver metro area. Some of the batches tested positive for Aspergillus, a fungus that the Marijuana Enforcement Division (MED) does not allow in any inhalable marijuana.
What Was Recalled
According to the MED health and safety notice, the recall covers 13 harvest production batches grown by Sweetwater Group, LLC, which does business as Sweetwater Cannabis. The notice lists strains such as Bigfoot Glue, Gelato 33, and Notorious THC, and specifies that affected retail packaging carries cultivation license number 403R-01141. Regulators say testing showed unacceptable overall levels of mold and yeast and, in several samples, Aspergillus.
Where It Was Sold
As reported by Westword, the flagged flower moved between November 16, 2025, and February 3, 2026, at 31 dispensaries around the state, with most of those shops in the greater Denver area. Westword reviewed the store list included with the MED notice and reports that retailers were notified over the weekend. Sweetwater, which operates an outdoor cultivation site in Walsenburg, cooperated with the MED on what the agency describes as a voluntary recall.
What To Do If You Bought It
The MED is urging anyone who purchased the affected products to stop using them and either destroy what they have left or return it to the store where it was bought so it can be disposed of properly. Consumers who experience any adverse health effects after using the recalled flower are advised to seek medical care right away and to report the problem through the agency's MED Reporting Form. Retailers that receive a recall notice are expected to follow the removal, quarantine, and documentation steps that are laid out in the MED health and safety notice.
Why Regulators Keep Issuing Recalls
State officials have been stepping up inspections and testing after a run of contamination alerts in recent months, and this latest action is one of several health and safety notices the MED has issued since late 2025, according to Colorado Public Radio. In a memo sent in late January, the MED warned licensees, especially extraction labs, to tighten up supplier vetting and called out cases where failed concentrate was being reworked in an attempt to clear testing.
The State Auditor is conducting a performance audit of the MED and has opened a public survey on health and safety advisories (HSAs) that runs through February 11. Public input will be included in the audit record, and experts have been debating whether the state's current Aspergillus limits strike the right balance between protecting consumers and keeping compliance feasible for growers, per Colorado Public Radio.
Bottom Line For Consumers
If you picked up cannabis flower with cultivation license number 403R-01141 or any of the batch names listed in the MED notice, stop using it and contact the shop where you bought it about a refund or safe disposal. People with weakened immune systems should be especially cautious and avoid inhaling any suspect flower, since Aspergillus can cause serious lung infections. Anyone with questions about a specific purchase or possible health effects can reach out to the MED through its reporting form and talk with their health care provider.
