A. Testing of Cattle in Quarantined Herds

1. Within six months of the date the quarantine was issued, an exposed herd will be tested at a date agreed upon by the owner or his representative and an authorized agent of the Livestock Sanitary Board. If a date to test an exposed herd cannot be agreed upon, the state veterinarian will establish a date to test the exposed herd and notify the owner in writing 30 days prior to the date established. An exposed herd will remain under quarantine and be tested until it has passed one complete negative test. When more than one herd test is required to obtain a complete negative test, the test date will be established by the procedures used to establish the initial herd test.

a. An infected herd will be tested on a schedule established in an approved herd plan or be tested at intervals of 60 days or less. The adult herd will be tested and continue to be classified as infected and under quarantine until it has passed one complete negative herd test, not less than 30 days following the date the last reactor was removed from the herd, and, in addition, a second negative herd test, no less than 180 days from the date the last reactor was removed from the herd. In addition, all infected herds must be tested six to 12 months following their release from Brucellosis quarantine, provided that some or all of their herd is still intact;

b. heifer calves weaned after 8 months of age, from a known Brucellosis infected herd, must be quarantined and held separate and apart from the known infected adult herd until they test negative for Brucellosis following their first calving; or

c. if heifer calves remain in a Brucellosis infected adult herd, the entire herd shall remain under quarantine until all the heifer calves have calved and the entire herd is tested negative for Brucellosis.

3. Any Brucellosis infected herd which has one or more reactors on more than one herd test, would be required to be adult vaccinated against Brucellosis and will be tested on a schedule established in an approved herd plan or be tested at intervals of 60 days or less. The herd will be tested and continue to be classified as infected and under quarantine until it has passed one complete negative test, not less than 30 days following the date the last reactor was removed from the herd and a second negative herd test, not less than 180 days from the date the last reactor was removed from the herd. In addition, the herd must be tested six to 12 months following its release from Brucellosis quarantine, provided that some or all of the herd is still intact.

B. Movement of Cattle from Quarantined Herds

1. Brucellosis reactors disclosed in a quarantined herd will be:

a. "B" branded on the left jaw;

b. identified with a reactor tag; and

c. removed from the herd and sold directly to slaughter or to an approved stockyard for sale to slaughter within 45 days from the date the animal is classified as a Brucellosis reactor.

a. All cattle over 6 months of age in beef herds, will be "S" branded and identified prior to movement from the quarantined premises by an authorized agent of the Livestock Sanitary Board. In cases where it is impractical to have exposed cattle branded on the farm of origin, the state veterinarian can authorize the movement of cattle from quarantined herds to a livestock auction market for branding and identification. Exceptions to this Subparagraph are:

i. steers and spayed heifers;

ii. official Brucellosis calfhood vaccinated heifers, no more than 8 months of age and in a herd participating in an approved herd plan to eliminate Brucellosis from the herd.

b. All cattle over 6 months of age in dairy herds, will be "S" branded and identified prior to movement from the quarantined premises by an authorized agent of the Livestock Sanitary Board. Exceptions to this Subparagraph are:

i. steers and spayed heifers;

ii. calves, no more than 6 months of age which were separated from the dam at no more than seven days of age, held separate and apart from the infected herd for at least 30 days, and be identified with an official ear tag prior to movement from the premises. In addition, they must be from a herd participating in an approved herd plan to eliminate Brucellosis.

3. When part 78, of the Code of Federal Regulations, is amended to restrict the movement of all sexually intact heifer calves from Brucellosis quarantined herds, all cattle, regardless of age or vaccination status, will be "S" branded and identified prior to movement from any Brucellosis quarantined premises by an authorized agent of the Louisiana Livestock Sanitary Board. In cases where it is impractical to have exposed cattle branded on the farm of origin, the state veterinarian can authorize the movement of cattle from quarantined herds to a livestock auction market for branding and identification. Exceptions are steers and spayed heifers.

C. All movements from Brucellosis quarantined herds must be accompanied by a VS Form 1-27, listing the individual identification of each animal to be moved. This form must be delivered to an authorized representative at destination. These permits will be issued by an agent of the Livestock Sanitary Board.

D. All intrastate and interstate movements from Brucellosis quarantined herds are restricted to an approved slaughtering establishment for immediate slaughter, directly to an approved quarantined feedlot, or to an approved livestock auction market for sale to an approved slaughtering establishment or quarantined feedlot. (Brucellosis reactors must be sold for slaughter only, either directly to an approved slaughtering establishment or through an approved livestock auction market for sale to such establishment.) Exceptions to §727. D are:

1. steers and spayed heifers over 6 months of age;

2. heifer calves under 12 months of age that are official calfhood vaccinates, and they originate from herds participating in an approved herd plan to eliminate Brucellosis from the herd.

E. Bull calves under 6 months of age that are nursed by Brucellosis reactor or exposed cows, may move from the quarantined premises under permit, provided they have been weaned for not less than 30 days immediately preceding movement. Exceptions to this Subparagraph are:

1. steers and spayed heifers;

2. heifer calves from beef herds that are no more than eight months of age and are in a herd participating in an approved herd plan to eliminate Brucellosis from the herd;

3. calves from dairy herds that are not more than 6 months of age which were separated from the dam at no more than 7 days of age, held separate and apart from the infected herd for at least 30 days, and be identified with an official ear tag prior to movement from the premises. In addition, they must be from a herd participating in an approved herd plan to eliminate Brucellosis.
