42.39.614    TESTING LABORATORY QUALITY ASSURANCE TESTING REQUIREMENTS

(1) Except as provided in (10), a licensee must submit for testing a sample of every test batch from a harvest lot of marijuana and process lots of marijuana-infused products, extracts, and concentrates intended for use by a customer prior to selling or transferring the marijuana item to a customer.

(2) All marijuana items intended for direct sale or transfer to customers shall be tested in its final form. The addition of any ingredient after final quality assurance compliance testing will require retesting.

(3) The cannabinoid profile/potency for each sample must include:

(a) THCA;

(b) THC;

(c) Total potential psychoactive THC for marijuana items that require the application of heat for administration/consumption only;

(d) CBDA; and

(e) CBD.

(4) The laboratory test sample and related lot or test batch fail quality assurance testing for moisture analysis if the results are greater than 12.0%.

(5) The laboratory test sample and related lot or test batch fail quality assurance testing for filth and foreign matter screening if the results are greater than the following action levels:

(a) 5.0% of stems 3mm or more in diameter; and

(b) 2.0% of seeds or other foreign matter.

(6) The laboratory test sample and related lot or test batch fail quality assurance testing for microbiological screening if the results are greater than the following action levels:

(a) Salmonella species: non-detectable in 1.0 gram of material;

(b) Shiga-toxin producing Escherichia coli (STEC): non-detectable in 1.0 gram of material; and

(c) Pathogenic Aspergillus species A. flavus, A. fumigatus, A. niger, and A. terreus: Each non-detectable in 1.0 gram of material.

(7) Microbiological testing using molecular methods must include an enrichment step that follows the protocol provided by the manufacturer, molecular method used, or product instructions for use. Decreasing the enrichment time outside of the range provided above is strictly prohibited.

(8) The laboratory test sample and related lot fail quality assurance testing for mycotoxins if the results are greater than the following action level:

(a) Total of Aflatoxin B1, B2, G1, G2: 20 µg/kg; and

(b) Ochratoxin A: 20 µg/kg of substance.

 

(9) A laboratory test sample and related lot or test batch fail quality assurance testing for residual solvents if the results are greater than the action levels provided in table 1.0.

1 Total butanes should be calculated as sum of n-butane and iso-butane.

2 Total hexanes should be calculated as sum of n-hexane, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane and 2,3-dimethylbutane.

3 Total pentanes should be calculated as sum of n-pentane, iso-pentane, and neo-pentane.

4 Total xylenes should be calculated as sum of 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene.

 

(10) Heavy metals will be tested at random. A laboratory test sample and related lot or test batch fail quality assurance testing for heavy metals if the results are greater than the action levels provided in table 2.0.
