When I read that it's not unsettling to me at all and, while I don't have the info I read way back when from some scientist that broke it down, it says basically the same thing. In essence it can be summed up by saying by the time one ingests and egg that has come from a 5 lb. hen given 3-4 drops, processed thru her body, and the minute amount that would exists in an egg, eaten and processed by my 200 lb body, I probably got a greater dose that was soaked thru my fingers while applying it to a hundred birds or so.
