Do wood countertops or butcher block tops harbor bacteria?

No. There is no good evidence that wood harbors more bacteria than plastic. There is evidence that many woods actually kill bacteria. Have you visited a real butcher shop of late? Do you see the butcher cutting the choice pieces of meat on granite or stone? No, the butcher uses what his profession has used for centuries – wood – butcher block. And his health inspection certificate behind his counter verifies the ease of clean up and disinfecting.
