But the point is that plastic is not *better*. You don't have to put a wood board in the dishwasher to sanitize it - it essentially sanitizes itself. I can't find the reference now, but I have also read that the more a plastic board is used, the more knife cuts it sustains, and the more difficult it is to sanitize it, even in the dishwasher, because the water can't get deep enough into the cuts.
Meanwhile, a wooden cutting board has inherent sanitizing properties. Again, I can't find the ref. now, (dangit!) but I have read that the dryness of the wood sucks the moisture out of the bacteria, killing them. Plastic doesn't do this.
I've written this here before - the way I clean my wood cutting board is to spray it with a solution of white vinegar, lemon juice and water, let sit a few minutes, then wipe any crumbs, etc., into the trash. Done. It's ready to use again and I don't have to wait for a dishwasher cycle.
