Event Overview:

As the legal cannabis industry continues to grow, issues remain for laboratories to accurately perform microbial contaminant testing. Laboratories must learn to navigate unclear regulatory guidance, limitations in current technologies, and the unavailability of qualified microbiologists to perform the work. Becoming ISO 17025:2017 compliant is only the first step, but to be truly successful, laboratories will need to embrace the finer details of microbiology analysis. Participants in this webinar will gain insight into:

  • Interpreting microbial contaminant regulations
  • Going beyond ISO 17025:2017 accreditation for microbial contaminant testing
  • Benefits and limitations of current technologies

Key Learning Objectives:

  • Understanding method validation and compliance testing requirements of state regulations
  • Limitations of ISO accreditation for microbial compliance testing and how to resolve remaining issues.
  • How to benefit from new technologies and when culture based methods may be more appropriate

Who Should Attend:

  • Cannabis laboratories: Quality Directors, Laboratory Directors, Technicians
  • Regulators
  • Industry
