Results from a comprehensive study indicate that granite countertops do not pose a health risk.

According to the Marble Institute of America (MIA), the “scientists conducted more than 400 tests of 115 different varieties of granite countertops…The stones tested include types of granite that comprise approximately 80 percent of the annual U.S. market share for granite countertops, based on the most recent market data available. The study specifically included types of granite most commonly used in countertops in the United States and more exotic stones that represent a tiny share of the market.”
