As used in this section "establishment" means a creamery, milk or cream collecting station, or place of business where milk or cream is purchased or assembled for processing or sale.
The board or its authorized agents may enter the premises or buildings of any establishment to collect samples of milk or cream delivered to the establishment.
Upon demand of the board or its authorized agents, the operator of an establishment shall submit containers of milk or cream delivered to the establishment to the board or agents before any milk or cream is removed or any substance or thing is added, and shall allow the board or agent to take a sample of one ounce in weight or less of milk or cream from each container for the purpose of applying any recognized test to determine the existence of disease in the cattle which produced the milk or cream.
The operator of the establishment shall furnish the board or agents the name and address of the person delivering each container of milk or cream to the establishment, and the name and address of the owner or caretaker of the cattle which produced the milk or cream.
The board or agent shall use due diligence to prevent contamination of the milk or cream while procuring samples and to delay as little as possible the normal operation of the establishment.
