I would like to believe it is harmless but I don't like reading: "International Agency for Research on Cancer lists zeolite as a Group 1 Carcinogen, a categorization used when there is sufficient evidence of mesothelioma carcinogenity in humans". And I think I'm probably more worried about this because my father died of Mesothelioma and he certainly wasn't in the production of asbestos, he wasn't even in direct contact with it, just in the same building and the asbestos wasn't even in powder form, it was stable, just lining big ovens. Of course, he was exposed back in the day when most people didn't even know asbestos was a carcinogen, many,many people are dying of it now who were not involved in the production of it but it takes 20 or so years for it to develop into cancer in the lungs, kind of like smoking cigarettes. And as for radon exposure and lead exposure, both are things we go to great lengths to avoid, we don't continue to be exposed and shrug our shoulders. Who would willingly drink water with lead in it or live in a house with radon without proper ventilation and where I live you can't sell a house that has lead paint or asbestos in it. I wouldn't worry about the Sweet PDZ so much if it weren't for the sifting that is required and the dust bathing that chickens do in it. Because asbestosis takes a long time to develop I don't worry about the chickens as much as I do myself and especially children. If you are the kind of person that likes to avoid as many carcinogens as humanely possible, such as, cigarettes, lead, asbestos etc. then I think using and sifting PDZ needs to be considered carefully.
