The truth about cutting boards and bacteria: "What, then, is the truth about cutting boards? Both plastic and wooden boards can hold on to bacteria for long periods of time. Both plastic and wooden boards allow for transference of bacteria to other foods. Luckily, we found that scrubbing with hot soapy water was an effective (though not perfect) way of cleaning both kinds of boards; the USDA also recommends the regular application of a solution of 1 teaspoon bleach per quart of water. Simply put, maintenance, not material, provides the greatest margin of safety."
