The growing conditions for medical cannabis are also ideal for the growth of potentially harmful microbes such as bacteria, fungi, mold and yeast. We use advanced microbial analysis to detect the presence of any harmful microbes. Firstly, an ELISA screening methodology is used, then a detailed petri plate analysis is performed to determine the amount of colony-forming units, indicative of microbe infection. A few of the microbes we test for include: Salmonella, Yeast, E. coli, and total aerobic bacteria. Additionally toxic chemicals produced by microbes, called mycotoxins, are detected by the use of Liquid Chromatography / Mass Spectrometry (LC/MS).
