temperatures, taken on separate days, exceed the limit of the

standard for the milk and milk products, the Commissioner shall send

a written notice to the person concerned. This notice shall be in

cause shall be determined, any milk or milk product involved shall

not be offered for sale as Grade A, and the dairy farm responsible
