(1) Except as provided in (10), a licensee must submit for testing every test batch from a harvest lot of marijuana and process lots of marijuana-infused product, extracts, and concentrates intended for use by a registered cardholder prior to selling or transferring the marijuana item to a registered cardholder. (2) Usable marijuana lots consisting of dried leaves and flowers must be tested for the following: (a) cannabinoid profile; (b) moisture analysis; (c) foreign matter screening; (d) microbiological screening; and (e) pesticides screening. (3) Marijuana concentrate and extract lots must be tested for the following: (a) cannabinoid profile; (b) microbiological screening; (c) residual solvents screening; and (d) pesticides screening. (4) Marijuana-infused products must be tested for the following: (a) cannabinoid profile. (5) The cannabinoid profile for each sample must include: (a) THCA; (b) THC; (c) Total THC; (d) CBDA; (e) CBD; and (f) Total CBD. (6) The sample and related lot or test batch fail quality assurance testing for moisture analysis if the results exceed the following limits: (a) moisture content no more than twelve percent. (7) The sample and related lot or test batch fail quality assurance testing for foreign matter screening if the results exceed the following limits: (a) five percent of stems 3mm or more in diameter; and (b) two percent of seeds or other foreign matter. (8) The sample and related lot or test batch fail quality assurance testing for microbiological screening if the results exceed the following limits: (a) Salmonella: 10 CFU/g; (b) E. Coli: 10 CFU/g; (c) Total of Aflatoxin B1, B2, G1, G2: 20 μg/kg; and (d) Ochratoxin A: 20 μg/kg of substance. (9) A sample and related lot or test batch fail quality assurance testing for residual solvents if the results exceed the limits provided in the table below. Residual Solvents Solvent* ppm Acetone 5,000 Benzene 2 Butanes 5,000 Cyclohexane 3,880 Chloroform 2 Dichloromethane 600 Ethyl acetate 5,000 Heptanes 5,000 Hexanes 290 Isopropanol 5,000 (2-propanol) Methanol 3,000 Pentanes 5,000 Propane 5,000 Toluene 890 Xylene** 2,170 * And isomers thereof. ** Usually 60% m-xylene, 14% p-xylene, 9% o-xylene with 17% ethyl benzene. (10) Heavy metals will be tested at random. A sample and related lot or test batch fail quality assurance testing for heavy metals if the results exceed the limits provided in the table below. Heavy Metals Limits; Unprocessed/Dry Flower Limits; Extract Inorganic arsenic 2.0 μg/g 10 μg/g Cadmium 0.82 μg/g 4.1 μg/g Lead 1.2 μg/g 6.0 μg/g Mercury 0.4 μg/g 2.0 μg/g (11) A sample and related lot or test batch fail quality assurance testing for pesticides if the results exceed the limits provided in the table below. Pesticides Analyte Chemical Abstract Services (CAS) Registry Number Action Level ppm; Unprocessed/Dry Flower Action Level ppm; Extract Abamectin 71751-41-2 0.5 2.5 Acequinocyl 57960-19-7 2 10 Bifenazate 149877-41-8 0.2 1 Bifenthrin 82657-04-3 0.2 1 Chlormequat chloride 999-81-5 1 5 Cyfluthrin 68359-37-5 1 5 Daminozide 1596-84-5 1 5 Etoxazole 153233-91-1 0.2 1 Fenoxycarb 72490-01-8 0.2 1 Imazalil 35554-44-0 0.2 1 Imidacloprid 138261-41-3 0.4 2 Myclobutanil 88671-89-0 0.2 0.6 Paclobutrazol 76738-62-0 0.4 2 Pyrethrins† 8003-34-7 1 5 Spinosad 168316-95-8 0.2 1 Spiromesifen 283594-90-1 0.2 1 Spirotetramat 203313-25-1 0.2 1 Trifloxystrobin 141517-21-7 0.2 1 † Pyrethrins should be measured as the cumulative residues of pyrethrin 1, cinerin 1 and jasmolin 1 (CAS numbers 121-21-1, 25402-06-6, and 4466-14-2 respectively).
