It shall be the duty of the county health officer to visit, without notice of his intention to do so, all mills, canneries, workshops, factories, or manufacturing establishments employing child labor within his county at least twice each year, or oftener if requested by the sheriff, and to promptly report to the sheriff any unsanitary condition of the premises, any child or children afflicted with infectious, contagious, or communicable diseases, or whose physical condition renders such child or children incapacitated to perform the work required of them. The sheriff shall promptly remove such child or children from such mill, cannery, workshop, factory, or manufacturing establishment, and order the premises put in sanitary condition. The judgment of the county health officer as to the physical condition of the children and the sanitary condition of the premises shall be final and conclusive.
