Transporting food as cargo in bulk form in intrastate commerce in a vehicle or vessel that has previously been used to transport in bulk form a cargo other than food does not constitute a violation of RCW 69.04.955 if:
(1) The cargo is a food compatible substance contained on the list adopted by the director and secretary under RCW 69.04.960;
(2) The vehicle or vessel has been cleaned as required by the rules adopted under RCW 69.04.960;
(3) The vehicle or vessel is marked "Food or Food Compatible" in conformance with rules adopted under RCW 69.04.960; and
(4) A certificate accompanies the vehicle or vessel when the food is transported by other than railroad car which attests, under penalty of perjury, to the fact that the vehicle or vessel has been cleaned as required by those rules and is dated and signed by the party responsible for that cleaning. Such certificates shall be maintained by the owner of the vehicle or vessel for not less than three years and shall be available for inspection concerning compliance with RCW 69.04.950 through 69.04.980. The director of agriculture and the secretary of health shall jointly adopt rules requiring such certificates for the transportation of food under this section by railroad car and requiring such certificates to be available for inspection concerning compliance with RCW 69.04.950 through 69.04.980. Forms for the certificates shall be provided by the department of agriculture.
