In reading the above article I quote: Our research was first intended to develop means of disinfecting wooden cutting surfaces at home, so that they would be almost as safe as plastics. My wife taught the class in Calif. for Food Handlers Cards and to have our church complyent in the new kitchen I volunteered to get my card from the state of Oregon and the info for both states are the same. Wood will transfer bacteria far greater than closed surfaced materials such as granit, steel, glass, and plastic. Its not that wood can't be cleaned to a safe condition but rather that most people do not know the proper prcedure in which to do so. And then you have to ask what type of finish to put on that will with stand the cleaning process over and over and yet stay on to not only ad to the looks of wood but also protect from bactera.
Do you want safe or almost as safe?
