You can chop all food on a granite chopping board thanks to its hard, non-porous surface. Granite is a hard stone that stands up well to knives and other sharp objects so that you can feel safe chopping everything from meats to vegetables on it. Just be aware of the damaging effects it can have on your knives and avoid hard chopping whenever possible.
Due to the non-porous nature of granite, its smooth surface is resistant to bacteria build-up. Raw food fluids and juices cannot seep into the interior, and their odors cannot become trapped. Prepare your raw fish or meat without worry; just be sure to clean your chopping board after each use.
