(iv)
Residual solvents screening. Certified labs must test for the solvents listed in the table below at a minimum. Except as otherwise provided in this subsection, a sample and corresponding product from which the sample was deducted fail quality assurance testing for residual solvents and must be disposed of consistent with WAC
314-55-097 if the results meet or exceed the limits provided in the table below. Residual solvent results of more than 5,000 ppm for class three solvents, 50 ppm for class two solvents, and 2 ppm for class one solvents as defined in
United States Pharmacopoeia, USP 30 Chemical Tests / <467> - Residual Solvents (USP <467>) not listed in the table below fail quality assurance testing.
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 (2-propanol) | | 5,000 |
Methanol | | 3,000 |
Pentanes | | 5,000 |
Propane | | 5,000 |
Toluene | | 890 |
Xylene* | | 2,170 |
* | Usually 60% m-xylene, 14% p-xylene, 9% o-xylene with 17% ethyl benzene. |
(v)
Microbiological screening. The sample and corresponding product from which the sample was deducted fail quality assurance testing for microbiological screening and must be disposed of consistent with WAC
314-55-097 if the results exceed the following limits:
| Enterobacteria (bile-tolerant gram-negative bacteria) | E. coli (pathogenic strains) and Salmonella spp. |
Unprocessed Plant Material | 104 | Not detected in 1g |
Extracted or Processed Botanical Product | 103 | Not detected in 1g |
(vi)
Mycotoxin screening. The sample and corresponding product from which the sample was deducted fail quality assurance testing for mycotoxin screening and must be disposed of consistent with WAC
314-55-097 if the results exceed the following limits:
(A) Total of Aflatoxin B1, B2, G1, G2: 20 μg/kg of substance; and
(B) Ochratoxin A: 20 μg/kg of substance.
(5) Test results reporting requirements. Certified labs must report all test results as required by this section into the state traceability system within 24 hours of completion of the tests.
(6) Retesting. At the request of the producer or processor, the WSLCB may authorize a retest to validate a failed test result on a case-by-case basis. All costs of the retest will be borne by the producer or the processor requesting the retest. Potency retesting will generally not be authorized.
(7) Remediation. Producers and processors may remediate failed products so long as the remediation method does not impart any toxic or deleterious substance to the CBD products obtained from a source outside the regulated system. Remediation solvents or methods used on the product must be disclosed to a licensed processor the producer or producer/processor transfers the products to; a licensed retailer carrying cannabis products derived from the remediated product; or consumer upon request. The product(s) the failed sample(s) were deducted from must be remediated using the same remediation technique. No remediated CBD products obtained from a source outside the regulated system may be sold, transported, or used in the processing of cannabis products until the completion and successful passage of quality assurance testing as required in this section.
(8) A licensee or certified lab that violates any of the provisions of this section is subject to disciplinary action, including possible summary suspension or revocation of the producer license, processor license, producer/processor license, or lab certification.
