Oklahoma medical marijuana patients are being told to double-check their stash after state regulators confirmed that a batch of flower that initially passed laboratory testing was later mixed with a batch that failed, creating a hazardous product now subject to recall. The Oklahoma Medical Marijuana Authority released updated information on the recall, which traces back to a licensed grow facility called Blue Collar Criminals Collective LLC.
According to news9.com, the recall was issued on Tuesday, October 20, after questions arose about a batch that had initially passed laboratory testing. That batch, identified as BIS091326-2, cleared testing on its own, but a portion of it was later mixed with another batch that had failed testing, according to the station. OMMA said that mixing is what made the combined product unsafe, while flower from batch BIS091326-2 that was never mixed with the failed material is not affected and remains safe, per KFOR.
How the Mix-Up Happened
Separate reporting indicates OMMA issued a mandatory recall covering two batches of medical marijuana flower after they failed required yeast and mold testing, the station reported. Investigators with the agency reviewed laboratory results alongside inventory tracking data to trace the recalled marijuana, identifying which dispensaries received the affected products and which patient transactions were involved.
The episode highlights a recurring headache for Oklahoma's cannabis regulators: once a batch passes testing, it can still end up contaminated if it's blended with material that didn't. A similar scenario played out in November 2025, when Vice Capital Extraction LLC voluntarily recalled pre-rolls after marijuana flower that failed microbial testing was combined with other flower material, contaminating the finished product, according to a recall notice posted by the state.
What Patients Are Being Told to Check
OMMA is urging patients to compare the batch numbers on their medical marijuana products against the agency's published list of recalled items, the same report noted. The agency has also rolled out an inventory-tracking feature in the Metrc system that flags affected batches and related packages with a warning symbol and a blue administrative recall alert, making it easier for dispensaries to spot problem inventory.
Patients and businesses can review the recall notice and the affected product list directly on OMMA's website. Dispensaries have separately been advised to pull products whose inventory status changed to test-failed, after a related episode in which roughly 19,000 samples from Greenleaf Labs had their statuses switched from test-passed to test-failed due to what regulators described as erroneous total yeast and mold testing, according to koco.com.
Tracing a Pattern of Testing Trouble
As the agency conducts package tracing to institute formal embargoes and recalls, dispensaries have been told they can get ahead of the process by removing flagged products from their shelves as soon as a package's status changes, the same report said. OMMA maintains a standing page outlining licensee recall responsibilities, underscoring that tracking down contaminated batches once they've entered the supply chain is an ongoing part of how the state polices its medical marijuana market.
For now, the message to patients remains straightforward: check batch numbers, watch for the blue recall alert in tracking systems, and consult OMMA's published list before using flower tied to Blue Collar Criminals Collective LLC.
