The tough task of safe food preparation is simple with the colorcode system that takes the risk out of cross contamination. The boards are color coded by food group. Theyre non absorbent and wont harbor food borne bacteria. The non skid surface wont dull knives, chip, crack, peel or warp. Theyre dishwasher safe and contamination can be further reduced with our matching knives. Colorcode cutting boards are the ultimate defense in the prevention of cross contamination. Exceptionally durable and essential for safe food preparation. The high density polyethylene is dishwasher safe.
