.03 Dairy Herds.

At least three times per year, a sample of milk or cream will be collected at the milk plant, creamery, or other location from each herd offering milk or cream for sale, by the office of Animal Health, personnel or by other persons approved by the Director, and the milk sample will be subjected to the milk ring test. Additional samples may be taken at the farm, if deemed advisable by the Director, and subjected to the milk ring test. A herd from which a suspicious or positive milk sample is received will immediately be placed under such restriction or quarantine as the Secretary shall order, until it has been established by official individual animal testing whether brucellosis exists in the herd.
