Cannabis Pesticide Residue Screening
For the past 30+ years, Anresco Laboratories has been a pioneer in the development of novel methods for pesticide residue analysis in foods (see: Glyphosate Testing). The company has since leveraged that expertise to become the leading cannabis laboratory for this analysis in California and likely beyond.
Anresco routinely analyzes cannabis flowers, extracts, edibles, and other matrices for the 66 pesticides required by the California Bureau of Cannabis Control (BCC). To achieve the challenging limits set, it utilizes both liquid chromatography tandem mass spectrometry (LC-MS/MS) and gas chromatography tandem mass spectrometry (GC-MS/MS).
Additionally, Anresco has the ability to screen for a much larger list of compounds upon request. Our most comprehensive cannabis pesticide screen also utilizes LC-MS/MS and GC-MS/MS via the “QuEChERS” method of extraction to analyze for ~300 different compounds at a limit of detection (LOD) of roughly 0.01ppm. This is the same pesticide residue screen that is used by the USDA National Organic Program (NOP) to regulate pesticide limits in organic products. Clients also have the option to run a single MRA by either GC-MS/MS (150+ compounds) or LC-MS/MS (100+ compounds). Click here to view a full listing of pesticides picked up by this method.
For those interested in testing for a specific pesticide, Anresco has the additional capability to screen for:
- PCB’s (Polychlorinated Biphenyls)
- EBDC Residues (Maneb/Mancozeb)
- Benomyl (carbendazim, MBC)
- Benomyl / carbendazim / MBC
- Buctril (BROMOXYNIL)
- Chlorophenoxy herbicides Screen
- Clofentezine (Apollo)
- Cyromazine (triguard)
- DPA (diphenylamine)
- Ethrel (ethephon)
- Ethylene Dibromide (EDB fumigant)
- Fluazifop (-p-butyl)
- Maleic hydrazide
- Naphthalene acetic acid (NAA)
- OPP (ortho phenylphenol)
- Organotins (Hexakis,Plictran,Vendex)
- Oryzalin (surflan)
- Paraquat (gramoxone)
- Phenylurea herbicides screen (linuron, diuron, monuron, etc.)
- Phosphine (Al / Zn Phosphide)
- Thiabendazole (TBZ)
- Thiocarbamates (Sutan, Vernam)
