All poultry slaughtered by any slaughterhouse licensed under this part shall be inspected by inspectors authorized by the department, both before and after slaughtering, and no poultry shall be slaughtered, or after slaughter, be sold, transported, offered for sale or transportation, or received for transportation, in intrastate commerce unless the slaughtering or the use after slaughtering in intrastate commerce is approved by an inspector.

The management of any processing establishment or slaughterhouse, or the owner of any poultry to be slaughtered requiring the services of an inspector in excess of eight consecutive hours on any workday, or in excess of forty hours in any workweek, or on legal holidays, shall pay to the department for any overtime inspection services the current state overtime rate for each hour of work performed by the inspector.

The department shall pay the inspector, or inspectors, for all overtime inspection services performed, provided that the party requesting or requiring the overtime inspection services shall, sufficiently in advance of the overtime period, arrange with the department for the services.
