The real question appears to be which do you find more terrifying, that the parasitic nematodes had access (and obvious motive) to invade the Yerba Mate or that you may be a somewhat less than spotless hippie?
I say this as someone who regularly shops at the local patchouli-scented food co-op and only buys non-GMO, organic tofu. Even though I wash my hair constantly, I once had a kale smoothie… so I’m gross.
PS. You and your subconscious are hilarious.
