Several marijuana products sold across Massachusetts were recently found to have mold and yeast in them above acceptable limits, the Cannabis Control Commission said in a health advisory Monday.

The strains — Slap N Tickle, Tiger’s Eye, Carbon Fiber, Frosted Jungle, Highland OG and Silver Kush — were sold as recently as last month, according to the announcement. They passed initial testing before the contaminants were found through additional compliance testing.
