Wood cutting boards are better than plastic. Firstly, wood cutting boards do not blunt knives. Secondly, and most importantly, wood is more hygienic than plastic. Studies have shown that bacteria do not care for wood. When deposited on several kinds of wood and left alone, food poison contaminants E. Coli, Listeria, and Salmonella, disappeared (99.9% gone!) over time. Plastic doesn't seem to have this antibacterial effect. It was discovered that it is easier to recover live bacteria from a plastic cutting board than from one made of wood. This because through the capillary action of dry wood, germs quickly disappear beneath the surface of the board, leaving the exposed area free of microbes. In contrast, bacteria sit on the hard plastic cutting board surface, ready to attack the next food item. Also, hand scrubbing with hot water and soap can clear microbes from the surface of new or used wooden cutting boards and new plastic ones, but knife-scared plastic boards are resistant to decontamination by hand washing.
