Detect microbial impurities in cannabis and hemp
The same conditions that are ideal for cultivation can also be ideal for the proliferation of microorganisms, bacteria, and pathogens. Microbiological contaminants can easily establish a foothold at any stage—from initial cultivation to finished product. Ingestion or inhalation of some microbes can lead to serious illness and health complications, particularly for patients and consumers with a compromised immune system.
Without federal oversight, testing rules differ greatly from state to state—leaving consumers varying levels of protection, and in some cases involving hemp analysis, no protection at all. We tackled this concern through diligent test method development, resulting in one of the nation’s largest selection of microbiological contaminant tests for the cannabis and hemp market.
SC Labs enables you to select the right solution for your unique testing needs. Our expansive offering covers a wide range of individual tests and six routine tests panels. Various bundled panel options were developed to target a comprehensive list of organisms, address state compliance rules, and meet guidelines established by the USP1, AHPA2, DCC3, or ORELAP4.

Our growing portfolio of microbiology testing solutions and relentless pursuit to progress quality standards is delivering an unprecedented number of advances for cannabis and hemp/CBD product safety.
Identifying microorganisms that are harmful holds great value for those in our industry. SC Labs is able to accomplish this through quantitative polymerase chain reaction (qPCR) technology—the future of DNA-based testing methods and screening for microbial impurities.
qPCR’s high sensitivity can detect and identify specific species of contaminants by utilizing the natural mechanisms of genetic amplification and engineered fluorescent probes. DNA probes are designed to bind to the 16s RNA region which is unique to particular species. When this binding occurs, a fluorescent molecule is cleaved from the probe, and the fluorescence is detected with calibrated instrumentation. The intensity of fluorescence, measured in refractory units (RFU), is captured by the instrumentation and displayed on an x,y graph.
SC Labs prides itself on providing reliable results, and our qPCR assay has been successfully validated against performance requirements set forth by the Bureau of Cannabis Control (BCC)1 and the US Food and Drug Administration (FDA)2.

- US Food and Drug Administration Guidelines for the Validation of Analytical Methods for the Detection of Microbial Pathogens in Foods and Feeds, 2nd Edition, April 2015, Single Laboratory Validation for a Qualitative Detection Emergency Use method guidelines for the detection of Shiga toxin-producing E. coli (STEC), Salmonella species, Aspergillus fumigatus, A. flavus, A. niger, and A. terreus.
Petrifilms are designed to detect and enumerate various micro-organisms quickly and efficiently. They have a ready-made culture medium that contains a cold-water-soluble gelling agent, nutrients, indicator dye, and a built-in grid to provide contrast facilitate the counting of colony forming units (CFU). Plating is a quality indicator for overall microbial load, and it cannot always discern harmful pathogens from beneficial or benign organisms. Species specificity is available for E. coli and Salmonella, while other colonies can be isolated and identified using qPCR.
3M Petriﬁlm plates are ISO 9002 certiﬁed for design and manufacturing, and they are included in the official methods of analysis of AOAC International. They are also recognized in the United States by the American Public Health Association; the USDA Agricultural Marketing, Food Safety and Inspection Service; and the US Food and Drug Administration.
SC Labs readily offers plating services with the following 3M Petrifilm products: Rapid Yeast and Mold Count Plates, E. coli/Coliform Count Plates and Aerobic Count Plates. We can also provide plating services with other 3M Petrifilm products, such as Enterobacteriaceae, among others.
Contaminants are everywhere, and ensuring prep surfaces and equipment don’t act as a transmission agent is an ongoing effort. Swabbing not only provides peace of mind before investing production resources, it pin-points high-risk areas and sources of contamination.
Environmental swabs are a tool that facilities use to screen and identify sources of contamination. A variety of different surfaces can be swabbed–table tops, vents, ventilation systems, fans, manufacturing equipment, etc. Each individual swab is in a self-contained tube that can be reliably resealed. The swabs are pre-moistened with a neutralizing buffer to ensure microbial organisms maintain viability during transport.
SC Labs can provide assistance with instructions on how to map, track, and swab facilities. Testing of the swabs for microbial impurities can be performed through qPCR or plating.
