Washington state cannabis regulator gives pesticide contamination update
- Marijuana Business Daily · Jun 9, 2023
Washington’s cannabis regulator provided an update on pesticide contamination in marijuana produced in the north-central area of the state, nearly two months after putting some MJ cultivators on “administrative hold” for an investigation.
The investigation began this year after random testing of marijuana grown in the area – once home to fruit orchards – detected the chemical compound DDE, which is created by the breakdown of the now-banned pesticide DDT.
Eighteen cannabis licensees are located in the “five mile stretch of land along the south end of the Okanogan River and north of Lake Pateros,” according to information presented at a June 7 Washington State Liquor and Cannabis Board (LCB) meeting.
Testing of soil samples collected in April is incomplete, but results show “levels of DDE/DDT and lead and arsenic in the soil samples are above state standards.”
