Records maintained by The Center for Disease Control confirm that there is absolutely no evidence of granite harboring bacteria or of anyone getting sick from bacteria in granite.

Additionally, the National Institute of Occupational Safety and Health, as well as the Hospitality Industry, give granite a clean bill of health. In a recent study, granite countertops provided the greatest reduction in bacteria count of all materials tested. Six countertop surfaces were contaminated with E.Coli bacteria, then washed and rinsed using dish soap and “normal and reasonable” cleaning practices.
