Wood cutting boards are safe if they are made from hard wood such as maple. Cutting boards make from soft wood such as pine should not be used. After using the cutting board for raw meats you should clean thoroughly with hot soapy water or in a dishwasher and then sanitize with a solution of 1 teaspoon bleach with 1 quart lukewarm water. For optimal safety have more than one cutting board in your home. Designate one to use for raw meat products and separate one to use for vegetables and fruits.
