I trust Now Foods most of the time, but like the reviewer below, I found so much dirt in my pack. I usually mix them into my smoothies and oatmeal, so I didn't realise the amount of soil in this until my mum showed it to me because. You can see them clearly because she soaks hers in water and all the dirt sinks to the bottom. And it's A LOT of black soil, not kidding...it's disgusting knowing how much of it I've ingested. Now I'm not too sure what to do with my 2nd pack.
