(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; and
(b) microbiological screening.
(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 moisture content of greater than 12.0 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: non-detectable in a gram of material;
(b) E. Coli: non-detectable in a gram of material;
(c) Culturable Mold: more than 10,000 colony forming units (CFU) per gram of material;
(d) Total of Aflatoxin B1, B2, G1, G2: 20 µg/kg; and
(e) 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.
