CharlesNeil – I do wonder however which woods they used

You can find the 1994 published article here: http://www.treenshop.com/Treenshop/ArticlesPages/SafetyOfCuttingBoards_Article/CliverArticle.pdf

The woods tested included “ash, basswood, beech, birch, butternut, cherry, hard maple, oak, and American black walnut.” From my quick read, the advantage of using wooden cutting boards over plastic seems to be due to absorption. That is, bacteria on wooden cutting boards were quickly absorbed beneath the surface while bacteria on plastic cutting boards remained on the surface because they had no other place to go. The study concluded (p. 21):

In these preliminary studies, we encountered unexpected difficulty in recovering inoculated bacteria from wood surfaces, regardless of wood species and whether the boards were new or used and untreated or oiled. This may be similar to the findings of Kampelmacher et al. and Ruosch, who contaminated wood surfaces and needed destructive procedures to recover bacteria that had gone beneath the surfaces to which they had been applied. Inoculated bacteria were readily recovered from plastic surfaces, regardless of the polymer and whether the boards were new or used.”

Moral of the story, just don’t cut too deeply into your wooden cutting board. ;)
