Well said. Reminds me of a raw milk study. 2 stainless steel vats of milk were tested. One was pasturized and one was raw milk straight from the cow. E coli was introduced into each vat and a short time later the milk was tested in each vat. The pasturized milk was rampant with e coli and the raw milk had no trace. Like Mr. Bush said, "the proper microbes will displace pathogens" and this study proved it.
