NAC584.2781. Brucellosis.

     1. All herds approved for the production of certified raw milk must be officially accredited as free of brucellosis and maintained free of that disease. The herd must be tested at intervals not to exceed every 90 days by the ring test in a state which is accredited to be free of brucellosis. All herds producing certified milk in states that are not so accredited must be tested by the ring test at intervals of not more than 35 days. The blood sera of each hoofed mammal in a herd must be tested for agglutination at intervals of not more than 12 months. All tests must be approved by the U.S. Department of Agriculture or by the Division of Animal Industry of the Department.

     2. After the tests are performed, any hoofed mammal which reacts to the test must be removed from the milking herds and disposed of by a method approved by the Division of Animal Industry. Animals which are suspected of being infected with brucellosis must be removed from the milking string and either sold for slaughter or retested at intervals of not less than 30 days until free of brucellosis before being readmitted to the milking string.

     3. If a ring test of a milk supply is positive, each hoofed mammal in the herd must be given a blood test and the tests for the herd must be negative before any milk from the herd may be sold as certified raw milk. After a hoofed mammal has reacted to such a test, the animal and its herd must be retested for blood agglutinins until a negative test of the complete herd indicates complete freedom from brucella infection.
