Licensee Recall Responsibilities

UNDERSTANDING THE RECALL PROCESS

Recalls are high-stakes regulatory events. A clear, pre-approved plan prevents panic, protects patient safety, and may help licensees maintain their licenses. This information provides general information regarding Recalls. The information is based on OMMA laws and rules, including 63 O.S. §§ 420 et seq., 63 O.S. §§ 427.1 et seq., 63 O.S. §§ 428 et seq., and OAC 442:10. To ensure compliance with all requirements, licensees shall rely on the full text of Oklahoma’s laws and rules. Questions about Recalls should be directed to the licensee’s legal counsel.

Key Definitions — Embargo vs. Recall

These are two distinct regulatory procedures. The terms are not interchangeable.

Embargo


(OAC 442:10-8-1(g)(1)): An on-site hold placed on medical marijuana and/or medical marijuana products found by OMMA to have failed to meet the requirements of Oklahoma law or rules; handled in violation of Oklahoma law or rules; or may be poisonous, deleterious to health or is otherwise unsafe. It is unlawful to remove, sell, donate, cultivate or otherwise transfer embargoed product without permission of OMMA. Every commercial licensee has a responsibility to assist in the embargo process.

Recall


(OAC 442:10-8-1(g)(2)): The process triggered when product tests above allowable thresholds, is subject to an embargo, is determined to be unsafe, or fails to meet OMMA laws and/or rules. Embargoed product that is sold or otherwise transferred must be recalled. Every commercial licensee has a responsibility to assist in the recall process.

1. Recall Triggers

The licensee shall initiate a recall immediately upon discovery that medical marijuana or medical marijuana products meet any one or more of the following criteria. Knowledge of a triggering event activates the licensee’s mandatory recall responsibilities under OMMA rules.


  • OAC 442:10-8-1(g)(2): Recall. If any medical marijuana or medical marijuana products test above allowable thresholds, are the subject of an embargo, are otherwise determined to be unsafe, or that otherwise fail to meet standards set forth in this Subchapter, the following shall occur:

    • (A) Any commercial licensee with knowledge of such event shall immediately notify the Authority;

    • (B) All such medical marijuana and medical marijuana products shall be immediately recalled and cannot be sold or otherwise transferred; and

    • (C) Every commercial licensee who is in possession or has ever had possession of such medical marijuana or medical marijuana products shall assist in the immediate recall, including, but not limited to, the following:

      • (i) Undertake necessary measures to ensure any affected medical marijuana or medical marijuana products are not transferred;

      • (ii) Create a distribution list of all commercial licensees that received the medical marijuana or medical marijuana products subject to the recall, including the licensee’s name, license number, address and contact information;

      • (iii) Create a list identifying all medical marijuana or medical marijuana products subject to the recall, including the category of medical marijuana or medical marijuana products, product description, net contents, batch number, and, if applicable, the name and license number of the commercial licensee that cultivated or manufactured the medical marijuana or medical marijuana product subject to the recall;

      • (iv) Provide notice to all affected licensees and consumers once identified; 

      • (v) Communicate with the Authority regarding the status of the recall and provide all required information and documentation to the Authority within two (2) weeks unless granted additional time by the Authority. 

      • (vi) The Licensee's failure to timely comply with the provisions of this subsection and/or provide required information and documentation to the Authority may result in revocation, suspension, and monetary penalties. The Authority may also issue a public recall notice, at any time, if it determines it is necessary to protect the public's health safety and welfare.
         
    • (D) The commercial licensee whose harvest or production batch is being recalled, and who bears responsibility for the recall, shall bear the costs for disposal of all medical marijuana waste subject to the recall in accordance with Oklahoma law and these Rules.

Conditions that Necessitate a Recall

  • Failed Contaminant Testing: The products test above allowable thresholds for any regulated contaminant analyte — pesticides, heavy metals, microbials, residual solvents, or mycotoxins — and are not eligible for remediation or decontamination under OMMA rules.
  • Embargo Status: The products are the subject of an OMMA embargo, or any embargoed medical marijuana or medical marijuana product was sold or otherwise transferred.

OAC 442:10-8-1(g)(1)(D): In the event any medical marijuana or medical marijuana products subject to an embargo are sold or otherwise transferred, such embargoed medical marijuana or medical marijuana products shall be recalled in accordance with these Rules.


  • Determined Unsafe: The products are otherwise determined to be unsafe for patient consumption or use.
  • OMMA Rule Violations: The products fail to meet OMMA rule requirements, including but not limited to improper testing or prohibited transfer under OAC 442:10-8-1(f).

1.1 Before Recall: Remediation and Decontamination

Not every failed test triggers an immediate recall. OMMA rules allow limited remediation and decontamination pathways.

  • Microbial failures (flower/trim) — Remediation: A final harvest batch of flower or trim that fails microbial testing may be remediated into a solvent-based concentrate. The remediated batch must be fully retested and pass all required analytes before release. If it fails retest, it must be disposed of per the Waste Management Act, 63 O.S. § 427a et seq.
    • OAC 442:10-8-1(i)(1)(F) A final harvest batch of medical marijuana flower or of medical marijuana trim that fails microbial testing may be remediated into a solvent-based concentrate. All other types of final harvest batches and final production batches that fail microbial testing shall not be remediated. A final harvest batch, that is remediated into a final production batch, must be fully tested and successfully pass all the analytes required under this Subsection. If that batch fails to pass these testing requirements, it must be disposed of in accordance with the Waste Management Act, 63 O.S. § 427a et seq. and these Rules.
  • Microbial failures — Decontamination: A final harvest batch or a final production batch of cannabinoid concentrate or extract that fails microbial testing may be decontaminated, then fully retested. A decontaminated batch that fails retest must be disposed of, except that flower/trim may still be remediated per OAC 442:10-8-1(i)(1)(F).
    • OAC 442:10-8-1(i)(1)(G) "(i) A final harvest batch that has failed microbial testing may be decontaminated and returned to the grower, provided that the harvest batch remains in its original form and was not processed into a solvent-based medical marijuana concentrate. (ii) A final production batch of a cannabinoid concentrate or cannabinoid extract that has failed microbial testing may be decontaminated. (iii) A final harvest batch or a final production batch that is decontaminated, in accordance with this Subsection, must be fully tested and successfully pass all the analytes required under this Subchapter. A decontaminated final harvest batch or final production batch that fails to pass these testing requirements must be disposed of in accordance with the Waste Management Act, 63 O.S. § 427a et seq. and these Rules, except that, a final harvest batch of medical marijuana flower or of medical marijuana trim may be remediated in accordance with Subsection (F)."
  • Mycotoxin failures: These failures shall NOT be remediated nor decontaminated and must be disposed. A failure in this category is a recall trigger.
    • OAC 442:10-8-1(i)(2)(H) If a final production batch fails mycotoxin testing, that batch shall not be remediated or decontaminated and must be disposed of in accordance with the Oklahoma Medical Marijuana Waste Management Act, 63 O.S. § 427a et seq., and these Rules.
  • Residual solvent failures: These failures shall NOT be remediated and must be disposed. A failure in this category is a recall trigger.
    • OAC 442:10-8-1(i)(3)(H) If a final production batch fails residual solvent testing, that batch shall not be remediated and must be disposed of in accordance with the Oklahoma Medical Marijuana Waste Management Act, 63 O.S. § 427a et seq., and these Rules.
  • Heavy metal failures: These failures shall NOT be remediated nor decontaminated and must be disposed. A failure in this category is a recall trigger.
    • OAC 442:10-8-1(i)(4)(H) If a final harvest batch or final production batch fails heavy metal testing, that batch shall not be remediated or decontaminated and must be disposed of in accordance with the Oklahoma Medical Marijuana Waste Management Act, 63 O.S. § 427a et seq., and these Rules.
  • Pesticide failures: These failures shall NOT be remediated nor decontaminated and ust be disposed. A failure in this category is a recall trigger.
    • OAC 442:10-8-1(i)(5)(I) If a final harvest batch or final production batch fails pesticide testing, that batch shall not be remediated or decontaminated and must be disposed of in accordance with the Oklahoma Medical Marijuana Waste Management Act, 63 O.S. § 427a et seq., and these Rules.
  • Potency discrepancies means package or label results exceeding the plus or minus fifteen percent (± 15%) tolerance of the Certificate of Analysis (COA) per OAC 442:10-7-1(d)(12). These discrepancies are governed by the retest workflow at OAC 442:10-8-1(j), not recall. A potency result only becomes a recall trigger per OAC 442:10-8-1(g) if it remains out of compliance after the prescribed retest procedures or is determined by OMMA to be unsafe for consumption.

1.2 Prohibited Transfers 

OMMA is not required to issue a notice of recall before the licensee’s responsibility to stop all transfers arises. The responsibility begins immediately upon the licensee’s knowledge of a recall condition.

  • OAC 442:10-8-1(f) Except as is authorized in these Rules, growers, processors, and dispensaries shall dispose of and shall not use, sell, or otherwise transfer any medical marijuana or medical marijuana products that exceed any testing thresholds or fail to meet any other standards or requirements set forth in this Subchapter.

NOTE

If a product meets any of the conditions above and is not eligible for or has failed remediation or decontamination, the commercial licensee must proceed immediately to the actions described in below. Delay in initiating a recall may constitute a violation of OMMA rules and may be grounds for administrative action,  including license revocation, suspension, and/or  monetary penalties per OAC 442:10-8-1(g)(2)(C)(vi). OMMA may also issue its own public recall notice at any time OMMA determines it is necessary to protect public health, safety, and welfare.

2. Recall Checklist

This checklist includes recall requirements.  Maintaining written documentation of the completion of each item provides a record of compliance.

Who this applies to

OAC 442:10-8-1(g)(2)(C) applies to every commercial licensee who is in possession or has ever had possession of the affected product.

  • Growers and Processors: Typically, the originating licensee responsible for the recall and the associated disposal costs under OAC 442:10-8(g)(2)(D).
  • Dispensaries: Responsible for removing product from shelves, notifying affected consumers, and preserving returned inventory under quarantine.
  • Transporters: Transporters must preserve manifests and chain-of-custody records.
  • Laboratories: Subject to the COA reporting obligations at 442:10-8-1(h). For laboratories, submission of a COA into the State’s inventory tracking system is sufficient to satisfy the testing laboratory’s reporting and retention duties.

Section 2.1 — Immediate Actions (First 24 Hours)

One of the primary goals in the first 24 hours is containment.

  • Immediate Notification to OMMA. Any commercial licensee with knowledge of a triggering event must immediately notify OMMA. The notification must include a copy of the applicable COA under 442:10-8-1(h).
    • OAC 442:10-8-1(g)(2)(A) Any commercial licensee with knowledge of such event shall immediately notify the Authority.; 
    • OAC 442:10-8-1(h) ...Commercial licensees shall immediately, in the manner and form prescribed by the Authority, provide notification to the Authority of any medical marijuana or medical marijuana products that have failed testing, and such notification shall include copies of the applicable COAs.
  • Halt Sales and Transfers. All affected products must be immediately recalled and cannot be sold or otherwise transferred. Necessary measures may include tagging, holds, and/or quarantine of affected batches.
    • OAC 442:10-8-1(g)(2)(B) All such medical marijuana and medical marijuana products shall be immediately recalled and cannot be sold or otherwise transferred.; 
    • OAC 442:10-8-1(g)(2)(C)(i) Undertake necessary measures to ensure any affected medical marijuana or medical marijuana products are not transferred.
  • Affix Embargo Tag. If the product is subject to embargo, it must be affixed with an electronic tag, physical tag, and/or other appropriate marking. It is unlawful to remove or dispose of embargoed product without permission of OMMA.
    • OAC 442:10-8-1(g)(1)(A) All such medical marijuana and medical marijuana products in the possession of a commercial licensee shall be immediately affixed with an electronic tag, physical tag and/or other appropriate marking or hold, including a hold in the State’s inventory tracking system, giving notice of the reason that the medical marijuana or medical marijuana product is subject to embargo. The affixed tag(s) and/or electronic hold shall further warn all persons not to remove or dispose of the medical marijuana or medical marijuana product by sale, donation, or otherwise transfer without permission of the Authority. It shall be unlawful for any person to remove or dispose of the embargoed medical marijuana or medical marijuana products without permission of the Authority.
  • Mandatory Recall Assistance. OMMA rules require commercial licensees that currently have, or previously had, possession of the recalled products to assist with the immediate recall. Any commercial licensee in the distribution chain that possessed the recalled products is subject to this responsibility.
    • OAC 442:10-8-1(g)(2)(C) Every commercial licensee who is in possession or has ever had possession of such medical marijuana or medical marijuana products shall assist in the immediate recall...
  • Notification of Affected Parties. The recall process includes providing formal, urgent notice to affected licensees concerning the recalled product and to affected consumers explaining that they should discontinue use or consumption of the recalled product.
    • OAC 442:10-8-1(g)(2)(C) Every commercial licensee...shall assist in the immediate recall, including, but not limited to, the following ...(iv) [p]rovide notice to all affected licensees and consumers once identified...”

Section 2.2 — Documentation Requirements 

Accurate traceability is vital. The following records must be maintained during the recall process.

Distribution List

Compile a comprehensive list of all commercial licensees that received the affected products. At minimum, the list must include the licensee’s name, OMMA license number, business address, and contact information (phone and email).

  • OAC 442:10-8-1(g)(2)(C)(ii) Every commercial licensee...shall assist in the immediate recall, including, but not limited to, the following ... (ii) [c]reate a distribution list of all commercial licensees that received the medical marijuana or medical marijuana products subject to the recall, including the licensee’s name, license number, address and contact information...
Product List

Draft a detailed list of the recalled products. At minimum, the list must include the product category (e.g., flower, edible, concentrate), product description, net contents (weight or volume), batch number(s), and, if applicable, the name and OMMA license number of the commercial licensee that cultivated or manufactured the product.

  • OAC 442:10-8-1(g)(2)(C)(iii) Every commercial licensee...shall assist in the immediate recall, including, but not limited to, the following ... [iii] [c]reate a list identifying all medical marijuana or medical marijuana products subject to the recall, including the category of medical marijuana or medical marijuana products, product description, net contents, batch number, and, if applicable, the name and license number of the commercial licensee that cultivated or manufactured the medical marijuana or medical marijuana product subject to the recall."
Supporting Records — COA Retention

Commercial licensees must maintain copies of all COAs for at least seven (7) years, kept on-site and readily accessible. Preserve all COAs, manifests, transporter records, and State inventory tracking system records related to the recalled batches.

  • OAC 442:10-8-1(h) Prior to accepting any sale or transfer of any medical marijuana or medical marijuana products, commercial licensees shall obtain copies of any and all COAs for every test conducted on the harvest batch(es), production batch(es), final harvest batch(es), or final production batch(es). Commercial licensees shall maintain copies of any and all COAs for at least seven (7) years and all records shall be kept on-site and readily accessible. Commercial licensees shall immediately, in the manner and form prescribed by the Authority, provide notification to the Authority of any medical marijuana or medical marijuana products that have failed testing, and such notification shall include copies of the applicable COAs. For medical marijuana testing laboratories, submission of a COA by the laboratory into the State’s inventory tracking system is sufficient to meet the testing laboratory’s requirement to report and maintain such records; all other commercial licensees shall obtain and maintain copies of any and all COAs required under this section and all records shall be kept on-site and readily accessible.

Section 2.3 — OMMA Reporting and Resolution 

Continue communication with OMMA and handle waste safely.

  • Maintain Active Communication. Continuously communicate with OMMA regarding the status of the recall.
  • Submit Final Documentation — Two-Week Deadline. Provide all required information and documentation to OMMA within two (2) weeks of the licensee’s knowledge of the triggering event, unless additional time is granted by OMMA. If the deadline cannot be met, the licensee must request additional time from OMMA in writing before the deadline passes.
    • OAC 442:10-8-1(g)(2)(C)(v) Every commercial licensee...shall assist in the immediate recall, including, but not limited to, the following ...(v) [c]ommunicate with the Authority regarding the status of the recall and provide all required information and documentation to the Authority within two (2) weeks unless granted additional time by the Authority.
  • Manage Disposal and Costs. Once cleared for destruction by OMMA, ensure the product is disposed of in accordance with the Oklahoma Medical Marijuana Waste Management Act, found at 63 O.S. § 427a et seq., and OMMA waste rules, found at OAC 442:10-8. Embargoed product may not be destroyed without permission of OMMA.
    • OAC 442:10-8-1(g)(2)(D) The commercial licensee whose harvest or production batch is being recalled, and who bears responsibility for the recall, shall bear the costs for disposal of all medical marijuana waste subject to the recall in accordance with Oklahoma law and these Rules.

COST RESPONSIBILITY

CONSEQUENCES OF NON-COMPLIANCE

Failure to timely comply with the recall requirements and/or to provide required information and documentation to OMMA may result in revocation, suspension, and monetary penalties. OMMA may also issue a public recall notice, at any time, if it determines it is necessary to protect the public’s health, safety, and welfare.

  • OAC 442:10-8-1(g)(2)(C)(vi) The Licensee’s failure to timely comply with the provisions of this subsection and/or provide required information and documentation to the Authority may result in revocation, suspension, and monetary penalties. The Authority may also issue a public recall notice, at any time, if it determines it is necessary to protect the public’s health safety and welfare.

Section 2.4 - Licensee Responsibility 

All Licensees’ Responsibilities

Any licensee in possession of a recalled product must immediately halt all sales, transfers, and processing of the affected inventory. Recalled product shall be maintained separately from active operational and retail areas, secured in a designated quarantine or other limited-access area, and clearly labeled as "Not for Distribution" or "Quarantined".


Growers and Processors:

Originators of medical marijuana and/or medical marijuana products bear the administrative and financial compliance responsibilities during a recall:

  • Notification: Upon the discovery of any recall-triggering event (e.g., contamination, failed testing, or adverse health events), the originating licensee must notify OMMA immediately.
  • Communicate Downstream: The grower or producer must identify all businesses that received the affected product and notify them of the product name, batch/lot numbers, the reason for the recall, and instructions for product return or destruction.
  • Effectiveness Checks and Reporting: An effective recall process typically includes measures to verify that affected licensees received the recall notice and responded as instructed. The process may also include regular status reports to OMMA regarding the progress of the recall, including the quantity of product recovered and the quantity that remains in the marketplace.
  • Financial Responsibility and Disposal: The commercial licensee whose harvest or production batch triggered the recall is responsible for bearing the costs of disposal for all resulting medical marijuana waste. The product must be permanently destroyed and documented accurately in the state inventory tracking system (e.g., using "Destruction - Recall" adjustment codes in Metrc).

Dispensaries:

Dispensaries are the frontline of consumer safety and must ensure recalled products do not reach the public, or recover them if they already have:Notification: Upon the discovery of any recall-triggering event (e.g., contamination, failed testing, or adverse health events), the originating licensee must notify OMMA immediately.

  • Point-of-Sale Holds: Removal of affected items from the sales floor, updating thePoint of Sale (POS) system to mark the inventory as unsellable, and moving it to a secured location to prevent inadvertent sales is required to occur as soon as possible.
  • Customer Outreach: Retailers must use their sales logs to identify any consumers who purchased the recalled product and contact them directly (via email, phone, or in-store signage) to explain health risks may exist and state that they must dispose of or return the item.
  • Adverse Event Reporting: Upon patient or customer reports of an injury or illness related to a product, the dispensary must immediately record this in the state inventory tracking system and notify both OMMA and the originating grower/processor without delay.
  • Coordination of Returns: Coordination with the distributor or originating licensee to return the quarantined products or execute witnessed destruction of the products on-site if directed by OMMA is vital.

Testing Laboratories

Testing facilities are crucial in detecting product that should be subject to recall. As a commercial licensee, labs are subject to the same responsibilities required of all commercial licensees during a recall:

• Immediate Notification of Hazards: If a laboratory detects contamination (like pesticides, heavy metals, or microbes) above allowable thresholds, or finds unknown/injurious compounds, the lab immediately notifies the licensee that submitted the sample and OMMA of the hazard. If the product has not entered commerce, laboratories simply notify the commercial licensee of the failed test.

• Further steps vary based on the analyte type. According to OMMA rules, a final harvest batch of medical marijuana flower or trim that fails testing can be remediated into a solvent-based concentrate only if it fails for the following specific analytes:

• Microbials

• Foreign materials and filth

• Water activity and moisture content

• It is important to note that for these three categories, only final harvest batches of flower or trim may be remediated. All other types of final harvest batches and final production batches that fail these specific tests cannot be remediated and must be disposed, though they may be eligible for decontamination depending on the analyte. Additionally, any batch that is successfully remediated into a solvent-based concentrate must be fully tested again and pass all required analytes before it can be sold.

• Conversely, OMMA rules explicitly prohibit remediation for batches that fail testing for the following analytes:

• Residual solvents

• Mycotoxins

• Heavy metals

• Pesticide residue

• If a final harvest or production batch fails testing for pesticides, heavy metals, mycotoxins, or residual solvents, the product cannot be remediated and must be disposed of in accordance with the Oklahoma Medical Marijuana Waste Management Act, 63 O.S. § 427a et seq.

• Data Submission: The lab is responsible for uploading the failed COA directly into the state's inventory tracking system.

• Prohibition on Retesting: Once a recall is issued, laboratories are explicitly prohibited from conducting additional compliance testing on the recalled packages.
