In a report on anti-bacterial soap, you mention the following: “in a study done at the University of Arizona College of Medicine, it was found that making a “super” clean environment may predispose children under 6 months of age to the development of asthma in later life.” Can you please point me to this study? Thanks, _Kam E, Belmont, CA
