I have 3, of various sizes, ALL wood, cut from a Maple countertop.

There was an experiment done a few years ago, out of curiousity, to see whether wood or plastic was 'safer'...(The semi-official common-sense line was that wood was naturally more dangerous, and that modern, clean plastic was easier to clean and sterilize..etc... )
   It turned out that, given the usual scratching and cut marks in each, if reasonable care was taken in washing, the # of bacteria present after a few hours was MUCH less on wood. There seemed to be some natural anti-microbial process in good old wood that made it 'generally' safer than plastic.


I read it in the paper, and also heard it in a consumer report on TV.
