ME LD1620

Establishes a testing limit for total yeast and mold contamination in adult use cannabis at 100,000 colony-forming units per gram, with additional microbial testing required only for health-injurious microbes such as E. coli, salmonella, and coliform bacteria

Creates an audit testing program allowing licensees to qualify for reduced testing requirements after passing 10 consecutive mandatory tests on different batches without exceeding contamination limits

Licensees approved for audit testing are exempt from mandatory pre-sale testing unless they fail an audit test, at which point mandatory testing resumes

Requires testing facilities to submit all mandatory test results to the Office of Cannabis Policy within 30 days, regardless of pass or fail status

Mandates public posting of anonymized testing results on the office's website quarterly, with a minimum 3-month delay from test completion date
