The Brucellosis Milk Surveillance test made with whole milk or cream and an approved antigen, in a manner and by a person approved by the United States Department of Agriculture and the State Board of Agriculture, may be used to indicate the possibility of the presence of reactors in the herd from which the milk or cream samples were taken. If the test indicates that reactors may be present in a herd, the State Veterinarian shall have the authority to conduct an official test of the herd in order to identify the reactors.
