Microbiological Testing

Every day, employees and customers are at risk of being negatively impacted by the presence and breeding of harmful microorganisms. Bacteria, molds, mites, and viruses can cause illness and can contaminate your products, leading to loss of production and quality.

Facilities Screening

Do you need a method for identifying potential sources of microbial contamination in your facility?

Plant pathogens can infect crops at the roots, crown, foliage, and reduce their ability to grow. Molds can also colonize the cannabis flower during development or after harvest, and similar pathogens can affect your water as well. Below we have testing services to help identify these contaminants.

Cannabis Microbiological Testing

Microbiological testing is included in the changes to OLCC testing requirements. Cannabis will need to be tested for microbiological contaminants in accordance with OAR 333-007-0390 starting March 1, 2023.

Samples will need to be tested for:

Shiga toxin-producing E. coli (STEC), Salmonella, and Aspergillus; A. flavus, A. fumigatus, A. niger, A. terreus.

Although public water systems use chlorine, ultraviolet light or ozone to kill E. coli, some E. coli outbreaks have been linked to contaminate municipal water supplies. The EPA recommends testing your well water once a year and with us, we can provide presence/absence testing or quantitative results for E.Coli and Total Coliform bacteria.

E.Coli & Coliform
Bacteria in Water

Cannabis attracts a variety of insects, and Spider Mites (Tetranychus Urticae) are no exception. While you might think of them as bugs, they aren’t insects and are more closely related to spiders with eight legs and a lack of antennae.

However, it’s unlikely you’ll notice any of these features because adult mites are only 1/50 of an inch long, and juveniles are even smaller, making them almost impossible to see with the naked eye

Powdery Mildew (Golovinomyces Orontii) Powdery mildews are easily recognized by the white, powdery growth of the fungus on infected portions of the plant host.

Bud Rot Bud rot develops in cannabis when (Botrytis Cinerea), a type of fungus, infiltrates the plant. The fungus then develops inside the plant, before symptoms become visible. Early signs of bud rot eventually start showing on and around infected buds in the form of darkening and softening of the plant surface.
