These lab test batches are called &lt;em&gt;Additional + [Test category]&lt;/em&gt; lab test batches; for example, &lt;em&gt;Additional Pesticides&lt;/em&gt; or &lt;em&gt;Additional Potency&lt;/em&gt; lab test batches. &lt;/p&gt;
&lt;p class=&quot;MsoNormal&quot; xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Effective August 25, 2026, additional lab test batches should be used for any of the following situations: &lt;/p&gt;
&lt;ul style=&quot;margin-top:0in&quot; type=&quot;disc&quot; xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;
&lt;li class=&quot;MsoNormal&quot;&gt;A license holder evaluates additional risks of a contaminant being introduced to the product through the manufacturing steps and needs to add testing outside of the standard compliance testing. They request the required compliance testing lab test batch and the additional lab test batch based on the increased risk. &lt;/li&gt;
&lt;li class=&quot;MsoNormal&quot;&gt;A license holder requests reanalysis of a batch, and the testing facility uses the additional lab test batch to report the analyte(s). &lt;/li&gt;
&lt;li class=&quot;MsoNormal&quot;&gt;A license holder requests retesting after reanalysis. They request the additional lab test batch that corresponds to the required testing. The testing facility will use the additional lab test batch to report the retested analyte(s). &lt;/li&gt;
&lt;li class=&quot;MsoNormal&quot;&gt;A license holder remediates product and needs to send a sample in for testing. They request the additional lab test batch that corresponds to the required testing. The testing facility uses the additional lab test batch to report the results. &lt;/li&gt;
&lt;/ul&gt;
&lt;p class=&quot;MsoNormal&quot; xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;These additional lab test batches can be used for individual analysis of an analyte or all analytes in a test panel (for example, they can be used to test only butane or all residual solvents). When the results are uploaded for additional lab tests, the sample will not be marked as &lt;em&gt;Test Passed&lt;/em&gt; or &lt;em&gt;Test Failed.&lt;/em&gt; The test status will be determined by the results of the compliance testing. In the case of use for retesting or post-remediation testing, the testing facility or license holder should inform OCM when testing is complete by sending an email to &lt;a href=&quot;mailto:testing.ocm@state.mn.us?subject=Testing%20complete&quot; target=&quot;_blank&quot;&gt;testing.ocm@state.mn.us&lt;/a&gt;. The license holder should then submit a ticket to &lt;a href=&quot;https://support.metrc.com/s/login/&quot; target=&quot;_blank&quot;&gt;Metrc Support&lt;/a&gt; to request that the test status be updated according to the results from the additional testing.&lt;/p&gt;

Note: Testing facilities are required to report results to the client and OCM simultaneously through Metrc.  &lt;/p&gt;
&lt;p class=&quot;MsoNormal&quot; xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;&lt;strong&gt;Please refer to the&lt;/strong&gt; &lt;a href=&quot;https://mn.gov/ocm/cannabis-technical-authority&quot; target=&quot;_blank&quot;&gt;&lt;strong&gt;Cannabis Technical Authority&lt;/strong&gt;&lt;/a&gt; &lt;strong&gt;for complete cannabis and hemp product testing information.&lt;/strong&gt; &lt;/p&gt;
&lt;p class=&quot;MsoNormal&quot; xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Testing facilities must have already notified OCM (by sending an email to &lt;a href=&quot;mailto:testing.ocm@state.mn.us?subject=Status%20update&quot; target=&quot;_blank&quot;&gt;testing.ocm@state.mn.us&lt;/a&gt;) that they meet the following criteria before reporting partial lab test results.  &lt;/p&gt;
&lt;ol style=&quot;margin-top:0in&quot; start=&quot;1&quot; type=&quot;1&quot; xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;

&lt;li class=&quot;MsoNormal&quot;&gt;The testing facility must inform the office that they will be reporting partial test results. &lt;/li&gt;
&lt;/ol&gt;
&lt;p class=&quot;MsoNormal&quot; xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Partial test results may be reported for the same Metrc tag as the compliance lab sample using the &lt;em&gt;Additional + [Test category]&lt;/em&gt; lab test batches. Results will be reported by testing facilities even though the tests were never requested through Metrc. Reporting the additional lab tests will change the test status to &lt;em&gt;Testing in Progress&lt;/em&gt;, but the sample will only be marked as &lt;em&gt;Test Passed&lt;/em&gt; or &lt;em&gt;Test Failed&lt;/em&gt; after full compliance testing results have been reported using the requested lab test batch. &lt;/p&gt;

&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;This guidance serves as an amendment to previous verbal OCM guidance. OCM had previously stated that the confirmatory test for a molecular method would need to be plating to demonstrate viability of the microbe. This guidance clarifies:  &lt;/p&gt;
&lt;ol xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;
&lt;li&gt;&lt;font face=&quot;Open Sans, Helvetica, Arial, sans-serif&quot;&gt;If the initial analysis was done using molecular testing, the confirmatory test may be either molecular testing or plating. &lt;/font&gt;&lt;/li&gt;
&lt;li&gt;&lt;font face=&quot;Open Sans, Helvetica, Arial, sans-serif&quot;&gt;If the initial analysis was done using plating, the confirmatory test must be done using molecular testing. &lt;/font&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;The &lt;a href=&quot;/ocm/assets/OCM_Cannabis_Technical_Authority_v2.0_tcm1202-678506.pdf&quot; title=&quot;OCM_Cannabis_Technical_Authority&quot; target=&quot;_blank&quot; xlink:title=&quot;OCM_Cannabis_Technical_Authority&quot; xmlns:xlink=&quot;http://www.w3.org/1999/xlink&quot;&gt;Cannabis Technical Authority&lt;/a&gt; (CTA) indicates that “If a pathogen is detected during a screening method, a confirmatory test is required to verify the pathogen.” The goal of confirmatory testing is to ensure that a pathogen detection result from the lab was not a false positive and to ensure that a detected microbe is the species of concern. Confirmatory testing may be done by the initial lab that detected a pathogen in a screening method or may be outsourced to another lab through subcontracting. &lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Given that molecular detection of pathogens confirms both the presence and identification of the pathogen, if a pathogen was detected after sample enrichment, it can be confirmed by a second molecular analysis of that enriched or extracted sample. The second molecular analysis may be done by the testing facility using the same molecular technique as the original screening analysis or may utilize a second molecular technique. &lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;If a testing facility that uses a molecular method for pathogen screening has already verified and utilizes plating for the confirmatory method, the testing facility may continue with that plan. Alternatively, plating may be used as a tool for communication with clients to validate the viable risk of the pathogen detected in a product and the lab may switch to use molecular testing for confirmatory testing.   &lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Due to the real risk of misidentification of pathogens detected by screening methods that rely on plating, if plating is used for the initial pathogen screening, OCM requires that testing facilities use a molecular detection method to confirm the specified pathogenic species was present.  &lt;/p&gt;</BodyText><Author/><id>758536</id><pubdate>2026-07-09T13:50:41Z</pubdate></list><list><metadata><Type><Description/><Title>Lab Bulletin</Title><Id>717254</Id><Key/></Type><DublinCore><Description/><Audience/><Title/><Publisher/><Source/><Rights/><Identifier/><Format/><Language>eng</Language><SubjectControlled/></DublinCore></metadata><Title>Lab Bulletin | LB-2026-04</Title><title>LB-2026-04 Compliance lab sample size for beverage products</title><url>&lt;custom:Link urlOnly=&quot;true&quot; type=&quot;Component&quot; destination=&quot;tcm:1202-741732&quot; templateURI=&quot;tcm:0-0-0&quot; origin=&quot;tcm:0-0-0&quot;  /&gt;</url><Date>2026-04-21T20:52:30Z</Date><ShortDescription>The Minnesota Office of Cannabis Management (OCM) is updating the required product sampling for the lab test batch for beverage products.  </ShortDescription><Subtitle>Compliance lab sample size for beverage products </Subtitle><publication>1202</publication><BodyText>&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;The Minnesota Office of Cannabis Management (OCM) is updating the required product sampling for the lab test batch for beverage products.  &lt;/p&gt;

&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;The CTA does not differentiate the required lab sample size for various finished products but requires 0.5% by mass or a minimum listed amount which is 200 mL for beverages. OCM is updating the requirement for beverage products to unit-based lab testing sample sizes based on the overall beverage batch size (see tables below).   &lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Note: All cannabis or hemp products made or sold by license holders must meet the requirements of the CTA. This includes testing all contaminants, potency, homogeneity and stability. If a lower-potency hemp edible (LPHE) manufacturer uses an out-of-state testing facility, the test results must cover all of the testing requirements of the CTA.   &lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;This change is effective immediately and will be incorporated into the CTA when it is next revised. &lt;/p&gt;

&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Please refer to the &lt;a href=&quot;/ocm/assets/OCM_Cannabis_Technical_Authority_v2.0_tcm1202-678506.pdf&quot; title=&quot;OCM_Cannabis_Technical_Authority&quot; target=&quot;_blank&quot; xlink:title=&quot;OCM_Cannabis_Technical_Authority&quot; xmlns:xlink=&quot;http://www.w3.org/1999/xlink&quot;&gt;Cannabis Technical Authority&lt;/a&gt; (CTA) for complete cannabis and hemp product testing information.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;The CTA requires the same lab testing to be performed on product in vape cartridges as for manufactured final products. Because the concentrates used to fill vape cartridges are sometimes unchanged between the initial extract and filling the vape cartridge, OCM will accept single-point testing of the product within the filled vape cartridge. Under this updated testing requirement, no testing is required for concentrate solutions before filling the vape, and all contaminants and potency must be evaluated for the products in the filled vape cartridges.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;In Metrc, products that are packaged into individual cartridges for vaporized inhalation should be given the item category CANNABIS VAPE CARTRIDGE or HEMP VAPE CARTRIDGE. The appropriate lab test batches that should be selected for compliance testing are either: &lt;em&gt;Non-Solvent Concentrate/Extract for Inhalation&lt;/em&gt; or &lt;em&gt;Solvent Based Concentrate/Extract for Inhalation&lt;/em&gt;, depending on the nature of the concentrate. Each product must also be evaluated for stability in the packaged cartridge.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;&lt;em&gt;Note: Homogeneity testing is not required but is recommended to demonstrate good manufacturing processes for the vape production.&lt;/em&gt;&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Please refer to Page 18 of the &lt;a href=&quot;/ocm/assets/OCM_Cannabis_Technical_Authority_v2.0_tcm1202-678506.pdf&quot; title=&quot;OCM_Cannabis_Technical_Authority&quot; target=&quot;_blank&quot; xlink:title=&quot;OCM_Cannabis_Technical_Authority&quot; xmlns:xlink=&quot;http://www.w3.org/1999/xlink&quot;&gt;CTA&lt;/a&gt; for required sampling information for concentrates.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;For each batch compliance analysis, the minimum lab sample size must be provided to the testing facility for analysis. For vape testing batches, the solution may be distributed across a number of cartridges, as long as the contained solution is 22 g or more. For example, if the vape is 0.5 g/cartridge, 44 cartridges would be sent to the lab for analysis.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;For each stability timepoint, the lab sample size of contained solution should be no less than 7 g (which can be distributed across a number of vape cartridges). For each recommended homogeneity test, the lab sample size is no less than 10 units.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;&lt;em&gt;Note: The total amount submitted to the lab may be less than the sum of the amount for the individual tests so long as the minimum compliance sample test amount is submitted and the testing facility has sufficient sample for the required testing.&lt;/em&gt;&lt;/p&gt;

&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Note: &lt;strong&gt;Homogenized composite batch sample&lt;/strong&gt; and &lt;strong&gt;representative sample&lt;/strong&gt; are defined in &lt;a href=&quot;https://www.revisor.mn.gov/rules/9810.0200/&quot; target=&quot;_blank&quot;&gt;Minnesota Rules, part 9810.0200, subparts 27 and 52&lt;/a&gt;.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Please refer to the &lt;a href=&quot;/ocm/assets/OCM_Cannabis_Technical_Authority_v2.0_tcm1202-678506.pdf&quot; title=&quot;OCM_Cannabis_Technical_Authority&quot; target=&quot;_blank&quot; xlink:title=&quot;OCM_Cannabis_Technical_Authority&quot; xmlns:xlink=&quot;http://www.w3.org/1999/xlink&quot;&gt;Cannabis Technical Authority&lt;/a&gt; for complete cannabis and hemp product testing information.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;This bulletin is an update to the sample handling and preparation methods at testing facilities provided in &lt;a href=&quot;https://www.revisor.mn.gov/rules/9810.3100/#rule.9810.3100.4&quot; target=&quot;_blank&quot;&gt;Minnesota Rules, part 9810.3100, subpart 4&lt;/a&gt;, due to the potential for very large sample volumes of infused edible products. OCM recognizes the technical difficulty of homogenizing a very large batch of infused edible products and is therefore providing this alternative method of selecting representative units of the product.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;For infused edible products that can be itemized into individual pieces or servings (such as gummies and chocolate bars), each testing facility shall either have 1) a documented procedure to homogenize the lab sample as received (before selecting the portion for analysis) or 2) have a documented randomization process procedure for selecting representative units of the product for compliance analysis. If a partial unit is analyzed for a certain method, the partial unit shall proportionally represent the composition of the whole unit.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;When randomized units are selected for analysis, at least 30% of the product shall be removed from packaging and evaluated for visual uniformity before selecting the random units for analysis. If the units lack visual uniformity, then the whole sample must be homogenized before selecting the portion for analysis.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Each testing facility must choose and clearly document its method of sample preparation in the facility’s standard operating procedures, and all employees must follow the written procedures consistently and uniformly.&lt;/p&gt;</BodyText><Author/><id>730633</id><pubdate>2026-07-08T21:28:28Z</pubdate></list><list><metadata><Type><Description/><Title>Lab Bulletin</Title><Id>717254</Id><Key/></Type><DublinCore><Description/><Audience/><Title/><Publisher/><Source/><Rights/><Identifier/><Format/><Language>eng</Language><SubjectControlled/></DublinCore></metadata><Title>Lab Bulletin | LB-2026-01</Title><title>LB-2026-01 Stability Test Reporting</title><url>&lt;custom:Link urlOnly=&quot;true&quot; type=&quot;Component&quot; destination=&quot;tcm:1202-717246&quot; templateURI=&quot;tcm:0-0-0&quot; origin=&quot;tcm:0-0-0&quot;  /&gt;</url><Date>2026-01-28T15:35:33Z</Date><ShortDescription>Minnesota’s Office of Cannabis Management (OCM) is providing testing facility instruction on how to report stability testing results for the lab sample batch evaluated at each stability timepoint.  </ShortDescription><Subtitle>Stability test reporting</Subtitle><publication>1202</publication><BodyText>&lt;h3 xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;How to report stability study results in Metrc&lt;/h3&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Minnesota’s Office of Cannabis Management (OCM) is providing testing facility instruction on how to report stability testing results for the lab sample batch evaluated at each stability timepoint.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;&lt;strong&gt;Note: A stability study is defined in the &lt;a href=&quot;https://mn.gov/ocm/cannabis-technical-authority&quot; target=&quot;_blank&quot;&gt;Cannabis Technical Authority&lt;/a&gt; (Section IX, Page 14).&lt;/strong&gt;&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Stability testing is required for all products. Product stability must be evaluated in the final packaged form to establish an expiration (or best-if-used-by) date for the product. Product stability must be established on the first batch for each cultivation or manufacturing process. If the cultivation or manufacturing process changes, stability must be demonstrated for the new cultivation or manufacturing process.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;For each stability test timepoint, the lab will document storage of a portion of a sample from one batch in the final packaged form. The sample must be stored at the conditions specified on the product label or, if none are indicated, at room temperature and not in direct sunlight until the stability test timepoint. The manufacturer must provide the licensed testing laboratory with an adequate sample volume in the final packaged form to generate a sufficiently sized composite of the samples at each stability test timepoint. The testing facility is not required to analyze the minimum sample volume at each timepoint. The manufacturer may test at whatever time increments are appropriate for the material. The manufacturer and testing facility will agree on a stability testing timeline for each product.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;At the stability test timepoint, the sample will be analyzed for microbial content (as specified in Section I), cannabinoid profile (as specified in Section VII), and any contaminant category that could leach from the packaging. For example, solutions stored in vape devices should be tested for heavy metals. Each manufacturer should evaluate if additional contaminant categories are relevant for stability timepoint analysis.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;To meet the stability requirements for each timepoint, the microbial content must meet those specified in Section I and the concentration of the cannabinoid present at the highest concentration must vary by less than 15% of the label claim, as compared to the potency determined at T0 or, if there is no label claim, from the amount determined at T0.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;&lt;strong&gt;Until data have been collected establishing evidence-based expiration (or best-if-used-by) dates, a cannabis product will have a six-month expiration date.&lt;/strong&gt; If a license holder has data to support a longer expiration date on the first batch, they can submit those data to the office for evaluation on a case-by-case basis. Stability testing must be initiated within three months for any new products. Failure to demonstrate six-month stability will result in an assigned expiration date according to the last demonstrated passing results for that product.&lt;/p&gt;
&lt;h4 xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Metrc actions to report stability study data&lt;/h4&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;&lt;strong&gt;T0 timepoint:&lt;/strong&gt; To initiate a stability study, a business should contact a testing facility and request the stability testing schedule that will meet their needs. Product stability should be evaluated on the first batch of a cultivation or manufacturing process; the business will submit the representative lab test sample to the testing facility with sufficient material for the batch compliance testing and all stability testing timepoints. The business should select the lab test batches for compliance testing and “Stability Study T0 (and the corresponding product type).&quot; The stability study test material will be in addition to or part of the representative sample material that is evaluated for batch compliance testing. The testing facility will perform the batch compliance testing and report the results for potency and microbial testing as both the compliance batch testing and “Stability Study T0 (and the corresponding product type).”&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;&lt;strong&gt;T1 timepoint:&lt;/strong&gt; The testing facility will retain the remaining lab sample from T0 and the compliance batch testing and hold it at their facility as agreed upon between the business and testing facility. At the agreed upon time point, the testing facility will pull sufficient material for the stability analysis. The results from this analysis will be reported for the same Metrc ID as the initial lab sample as “Stability Study T1 (and the corresponding product type).” Note: the business will NOT request testing for “Stability Study T1” through Metrc. The results can be reported without the test being requested by uploading the appropriate set of results from the Lab Test Batch upload guide. If the business requests “Stability Study T1 (etc.)” testing, their entire batch will be on hold for the entirety of the stability analysis.&lt;/p&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;&lt;strong&gt;Tn timepoints:&lt;/strong&gt; The testing facility will continue to retain the lab sample and report additional testing timepoints in sequential order as agreed upon with the business. If the testing facility generates failing results, they will report the failing results which will indicate that the product stability was demonstrated as the Tn-1 timepoint. If a product demonstrates passing results at the last tested timepoint, additional stability studies are not required and the product may be assigned a stability of the last timepoint with passing results.&lt;/p&gt;
&lt;h4 xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;Lab Test Batch upload guide&lt;/h4&gt;
&lt;p xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;OCM will provide the templates for reporting results in a .csv file for all lab test results. The reporting guide has the lab test batch configurations that will be used to report each stability testing timepoint. T0 is reported along with the compliance testing results for the batch, and a testing facility will upload the sequential timepoints: T1, T2, at the agreed upon schedule as determined with the laboratory. The testing results uploaded for the stability timepoint will not override the initial test results as long as the testing facility ensures that it uploads the next sequential stability timepoint. The testing facility should ensure that the appropriate product category is used to report the stability study results.&lt;/p&gt;</BodyText><Author/><id>717246</id><pubdate>2026-07-08T21:28:28Z</pubdate></list></results>
