Safe Side is a new concept in cutting boards. It makes food prep safer with color coded buttons that help you to avoid cross contamination of food. Use green side for fruits and vegetables and red side for meats, poultry and seafood. The buttons make a safer cutting board in that they"re also non-slip so the cutting board stays where you put it.
