OMMA advises removing affected products from inventory now if they were tested for Total Yeast and Mold by Greenleaf during the affected timeframe.

Yes. We are accepting new clients affected by this situation.

Turnaround time depends on current volume and test type. Our standard turnaround time is 3–5 business days. We will not cut corners, but our expanded team is working extended hours to process samples quickly without compromising accuracy.

Not necessarily — OMMA is still identifying which products are affected. However, proactively retesting can be an act of good faith toward both OMMA and your customers. Even if your product is not ultimately flagged, showing that you’ve taken steps to ensure safety and accuracy can help maintain or rebuild patient trust and protect your brand’s reputation in a competitive market.

Historically, the answer has been no — licensees are typically responsible for the cost of retesting. This aligns with OMMA’s recall procedures, which generally place the burden of retesting and compliance on the licensee. While OMMA has not announced any reimbursement for this situation, we recommend planning for the cost of retesting now so you can act quickly if your products are affected.

Call us at 918-872-7015 to set up onboarding. The fastest way is to drop your samples at our lab; pickup may be available if drop-off is not possible.

For products that are in test failed status for microbials at Greenleaf, you are allowed to retest per OMMA Rules (omma.ok.gov/rules). You will be required to have two full-panel passing results to over-turn the failure. Alternatively, you can waste the product.

So far, approximately 19,000 total packages were impacted – however this number may change as the formal recall or embargo is placed.

OMMA has stated that during a routine compliance inspection, inspectors identified a concern requiring further scrutiny and analysis, specifically related to Total Yeast and Mold testing. Due to the immediate risk to public health and safety, OMMA suspended Greenleaf Labs’ license on an emergency basis.

OMMA says the potential issue applies to products tested by Greenleaf Labs for Total Yeast and Mold between April 2023 and July 31, 2025.

OMMA is still identifying the specific products that were improperly tested. Overnight on August 13, approximately 19,000 samples tested by Greenleaf were changed from “test passed” to “test failed” in Metrc.

OMMA will release more details once their analysis is complete. In the meantime, products may already show a “test failed” status in Metrc.

You can find official recall or embargo notices on OMMA’s website. We recommend checking this page daily for updates related to Greenleaf Labs’ testing.
