1. A. Licensees shall sample every batch of product to ensure compliance with the standards of quality outlined below. Licensees shall not release any batch of product for sale until the representative sample has been verified as compliant. Batches may be tested prior to portioning or packaging.
2. B. Sample verification shall be by means of the issuance of a certificate of analysis from the approved laboratory conducting the sample analysis issued to the Department of Health and the originating facility no later than 24 hours after testing is complete.
3. C. Any batch with a sample failing one or more of the tests (by exceeding allowable limits for contaminants or residues) shall be remediated or destroyed, at the option of the licensee. A batch shall only be remediated once, and if subsequent sampling fails to correct the exceedance, the affected batch shall be destroyed.
4. D. Sample medical marijuana waste held at an approved laboratory shall be destroyed within 60 days of completion of testing.
5. E. Minimally-processed plant material shall be subject to all testing requirements below except testing for solvent residues.

6. F. Medical marijuana samples shall be required to meet the following standards of quality:

   1. 1. microbiological contaminants:

      1. a. mold/yeast <100,000 CFU/g;
      2. b. pathogenic Escherichia coli and Salmonella spp. < 1CFU/g;
      3. c. aflatoxins < 20 ppb;
      4. d. ochratoxins < 20 ppb.

   2. 2. solvent residues:

      1. a. butanes < 800 ppm;
      2. b. heptanes < 500 ppm;
      3. c. benzene <1 ppm;
      4. d. toluene <1 ppm;
      5. e. hexanes < 10 ppm;
      6. f. xylenes < 1ppm;
      7. g. ethanol < 5,000 ppm.

   3. 3. heavy-metal contaminants:

      1. a. arsenic < 10 ppm;
      2. b. cadmium < 4.1 ppm;
      3. c. lead < 10 ppm;
      4. d. mercury < 2 ppm.
   4. 4. pesticide residues: see Table 1 for maximum contaminant levels for finished products; any pesticide not listed shall not have detectable residues in finished products.
   5. 5. homogeneity: each aliquot shall have a variance of no more than plus or minus 15 percent of the total average result for THC content.
   6. 6. potency: the product shall have a variance of no more than plus or minus 15 percent of the THC content specified on the product label.
