LCB Testing Changes

The Washington State Liquor Control Board recently released their amended changes to the I502 QA testing process.  These changes are significant and will apply to all Producer/Processors starting August 31st, 2017.  Here at Xchemistry and Molecular Testing Labs, we have provided details on the specific changes to testing with flower, microbials and usage of residual solvents and pesticides.  We look forward to working with you as these new requirements are implemented.

WSLCB Publication on New Rule Changes:

·      Mycotoxin - Mycotoxin screening is now required for flower products and all extracts, unless the extract was made with previously-tested flower.  Standard testing now requires five parts of the QA process:  potency, moisture, foreign matter, microbial and mycotoxin review

·      Residual Solvents Screening - Each solvent based extract now requires a residual solvent test, including CO2, BHO, ethanol, and all food grade solvent extracts.  Labs must now screen for fifteen unique solvents and the results must be below the ppm as listed down below

·      Microbial Tests and Changes to Limits - Specific tests such as aerobic bacteria, coliform, and yeast/mold will no longer be required on standard QA testing.  Enterobacteriaceae limits have been raised from 1,000 cfu/g to 10,000 cfu/g for raw plant material.  Lastly, the microbial screening is no longer required for extract types that destroy microbes, such as BHO, CO2 and ethanol

·      Pesticide Action Levels – For medical products, pesticide usage has been modified to include additional analytes and their acceptable action level ppm.  Specific analytes are listed in the included link down below.  The action level for all other pesticides that are not listed in the table is .1 ppm
