No person affected with tuberculosis or other communicable disease in a transmittable stage shall be employed in any department where any product is handled or prepared. The commissioner, when he has reasonable grounds to believe such action necessary, may require a medical examination of any person handling edible products and a certificate of a duly licensed physician showing the absence of such disease as a condition precedent to such continued employment.
