In this free 90-minute webinar, subject matter experts share insights into pesticide residue and mycotoxin method development, a US perspective on pesticide and mycotoxin testing, good manufacturing practices, and navigating the challenges of pesticide testing for various cannabis sample types. Originally aired February 26, 2021.
Key laboratory personnel responsible for method development and method validation.
Participants will be able to identify inherent regulatory and analytical challenges of evaluating chemical contaminants within cannabis and cannabis-derived products.
Pesticide residue and mycotoxin testing is challenging but even more so when testing for the cannabis market. It is important to understand the basics of method development and validation needed to develop a robust trace level method. This overview will help labs understand the amount of work involved so that realistic resource planning and timelines can be developed.
Testing requirements for pesticide residues and mycotoxin in cannabis and cannabis derived products vary from state to state and can be confusing to manufacturers and producers. Questions on what residues to test and how to test them are the most often asked. The talk will address these questions and look at some approaches that can help build confidence in materials and products.
An overview of the Canadian and international heavy metal cannabis testing landscape will be presented.
With the enormous variety of cannabis and hemp products requiring pesticide and mycotoxin testing come an array of challenges. From sample extraction methods to matrix suppression, this talk will provide an overview of these issues and strategies to mitigate them.
