Our great Chop & Chop cutting mats also are available in color-coded packs that will help prevent the possibility of cross-contamination between foods. They help you manage cutting tasks and ensure maximum sanitation in food preparation. The handy color chart included instructs employees by color and picture which mat is to be used with different food types. The Chop & Chop board is an innovative concept of strong but flexible cutting mats that protect kitchen surfaces from marring while also allowing you to funnel food directly into pans, bowls or woks. The pliable surface of the mats cushion knife blades when chopping, thus extending the life of your knife. Antibacterial properties are blended into the resin and will not wash or wear off but will actively inhibit the growth of bacteria. The mats are NSF approved and meet all FDA standards.
