Acutting board must be set aside and shown to manager when it is

A cutting board must be set aside and shown to a manager if the person who used it cut up something such as raw meat and then used the board to cut up fruit. This would be a form of cross-contamination and could cause many problems. This is a way that bacteria could be passed from one dish to another. This could cause a customer to either have an allergic reaction or to become violently ill.
