After reading Jeff’s response I don’t have a lot to add. I’m simply more cautious regarding human pathogens and think that, based on current research, even the best made compost tea has the potential to spread these pathogens in a worst case scenario. That no one has reported to have been poisoned yet does not mean that no one has ever been poisoned (this type of poisoning is notoriously underreported), nor does it mean that no one can ever be poisoned. Additionally, I’ve learned the hard way to be extremely skeptical of claims and testimonials and I simply don’t accept that something works because someone says so unless I’ve seen exactly how conclusions were reached —I don’t care if we’re talking about a backyard gardener, a professor with five Ph.Ds or the President of the United States.
So, probably the best way for me to conclude is by adding my voice to Jeff’s calling for more testing of these compost teas—both for the presence of human pathogens and for their efficacy—and by pointing out that, in my opinion, the home garden is not the place to run these experiments.
