The humidity plus there’s a video on youtube showing them sorting leaf on the floor of the factory right in the middle of everything . They blender then went on to say “...we’ll then wet this down and let it sit here overnight ..” so they are blending on the floor where machinery and people walk and leave residue. Then let it sit for 8 hours in the moist air on the floor. It’s right in the video. So some guy steps in oil In the parking lot, or dog crap, or who knows what, then walks into the factory , there’s a chance for cross contamination.
And I take it the blender and everyone else knew it was being filmed rather than the video being shot via a modern-day Upton Sinclair with a hidden camera?
