I would just wash it off and reuse it...
The myth is that wooden boards are so porous that harmful organisms such as salmonella, e-coli and listeria soak in, are hard to remove, and easily contaminate other foods placed upon it later.
The myth has been compounded with the belief that plastic, because it is not porous, can be more easily and safely cleaned. These beliefs were so widely held by everyone including health officials that no one actually bothered to test them until 1993. Microbiologists at the University of Wisconsin's Food Research Institute contaminated wooden cutting boards and plastic ones with all bacteria that cause food poisoning.... Guess what?
Without washing, without touching it, the bacteria on the wooden board died off in three minutes. On the plastic board? The bacteria remained and actually multiplied overnight. It seems wood has a natural bacteria-killing property, plastic and glass don't."
