Granite bacteria resistance
According to a recent study conducted by the Hospitality Institute of Technology and Management in Minnesota (an organization that develops educational materials and research for the retail food industry), if bacterial contamination of the kitchen countertop is a concern, granite is a good choice. The study measured the bacteria-resistance capacity of six common countertop materials. Each surface was contaminated with E.coli (nearly 2 billion of the microorganisms), washed and rinsed with soap and water and then sanitized with a vinegar-and-water solution. The results speak for themselves.
Surface microorganisms eliminated by cleaning:
Stainless Steel: 85,113,804
Granite: 79,432,823
Laminate: 498,884
Ceramic Tile: 293,765
Concrete: 32,810
Wood: 2,080
