Regulations – Chapter 17 – Swine

Swine herds may be validated or revalidated on a negative herd test of all breeding swine six (6) months of age and over provided that any herd with a history of Brucellosis has first qualified for validation by completing one of the plans outlined in Section IV, of these regulations.

(Adopted January 6, 1982, effective March 1, 1982.)

A swine herd may qualify for revalidation on a negative herd test of all eligible swine conducted within 10 to 14 months of the last validation date or establish that at least 20 percent (20%) of adult breeding swine where blood tested under the market swine testing program during the year, and that at least one-half (1/2) of the MST sampling occurred during the last six (6) months of its validation period.

(Adopted January 6, 1982, effective March 1, 1982.)

Individual herds must disclose no evidence of infection at time of validation or revalidation.

(Adopted January 6, 1982, effective March 1, 1982.)

Feeder swine of lesser status but not under quarantine may be held on validated herd premises without test provided such swine are maintained in isolation, separate and apart from all breeding stock.

(Adopted January 6, 1982, effective March 1, 1982.)

Swine may be consigned to slaughtering establishment or to an approved livestock market for sale and shipment to slaughtering establishments without test, provided they are transported directly to holding pens at the slaughtering establishment. Such swine may not be diverted enroute for any other purpose.

(Adopted January 6, 1982, effective March 1, 1982.)

No test requirements on breeding swine originating from Validated Brucellosis Free Herds. Such swine must be moved directly, must not have been in contact with swine of lesser status, and must be accompanied by a properly issued Official Health Certificate.

(Adopted January 6, 1982, effective March 1, 1982.)

Breeding swine originating from non validated herds must have a negative test within 30 days prior to date of entry. These animals must be held in isolation and pass an additional negative test 60 to 90 days from date of test for entry before being added to the herd.

(Adopted January 6, 1982, effective March 1, 1982.)

If infection is disclosed in swine herds, one of the following plans should be selected for eradicating the disease and for subsequent qualifying the herd for Validated Brucellosis Free status, if desired.

1. Plan 1. This Plan is recommended for commercial herds found infected. The following procedures should be carried out:
   1. Market the entire herd for slaughter as soon as practicable.
   2. Clean and disinfect houses and equipment.
   3. Restock premises with animals (from Validated Brucellosis Free Herds) placing them on ground that has been free of swine for at least 60 days.
   4. After two consecutive negative tests not less than 60 nor more than 90 days apart, the herd is eligible for Validated Brucellosis Free Herd status.
2. Plan 2. This Plan is recommended for use in infected purebred herds only where it is desired to retain valuable blood lines. The following procedures should be carried out:
   1. Separate pigs from sows at 42 days of age or younger and isolate.
   2. Market infected herd for slaughter as soon as practicable. Infected sows should not be rebred and should be slaughtered as soon as possible. Complete isolation of infected animals is essential. The separated weanling pigs from the nucleus for establishment of the infection-free herd.
   3. Test the gilts to be used for the following breeding season about 30 days before breeding. Save only the gilts that are negative. Breed only to negative boars.
   4. Retest the gilts after farrowing and before removing them from individual farrowing pens. Should reactors be found, they should be segregated from the remainder of the herd and slaughtered as soon as possible. Select only pigs from negative sows for breeding gilts.
3. Plan 3. This Plan is not recommended in general, but it has been found useful in herds where only a few reactors are found and where no clinical symptoms of Brucellosis have been noted. Carry out the following procedures:
   1. Market reactor for slaughter.
   2. Retest herd at 30 day intervals removing reactors for slaughter until the entire herd is negative.
   3. If the herd is not readily freed of infection, abandon this Plan in favor of Plan 1 or Plan 2.
   4. Following two consecutive negative tests not less than 90 days apart, the herd is eligible for Validated Brucellosis Free Herd status.

All breeding swine, moving from non-validated Brucellosis-Free Herds, must be tested at owner’s expense within 30 days prior to change of ownership.

(Adopted January 6, 1982, effective March 1, 1982.)

All breeding swine (sows and boars) moving through livestock markets must be tested for Brucellosis at the first point of assembly by the Market Veterinarian, at the owner’s (seller’s) expense, or if funds are available at State and/or Federal expense. The accredited veterinarian shall submit the samples, along with records of the animals bled, to the state or Federal inspector on duty at the stockyard. The inspector will centrifuge the blood, pour off the serum and forward the serum to the State/Federal BrucellosisLaboratory in Jackson , Mississippi , where the samples will be tested for brucellosis.

1. Herds of origin traced from a positive brucellosis test will be quarantined.
2. All swine herds quarantined because of Brucellosis will be required to conform to the Uniform Methods and Rules of the United States Department of Agriculture for Brucellosis Eradication in order to be eligible for quarantine release.

(Adopted January 6, 1982, effective March 1, 1982.)

All swine samples tested at the Brucellosis Laboratory will be submitted to the Mississippi Veterinary Diagnostic Laboratory for pseudorabies testing. All swine sera samples received in the Diagnostic laboratory for diagnostic services will be tested for pseudorabies and the sera submitted to the Brucellosis Laboratory for Swine Brucellosis testing when adequate sera is available.

1. All positive pseudorabies (PR) test reports will be sent to Veterinary Medical Officers (VMO) for investigation of herds of Origin.
2. PR infected herds will be quarantined by the VMO.
3. All owners of the infected swine will be required to enter into a clean-up plan under the supervision of the VMO’s to eradicate pseudorabies from their herds.
4. VMO’s will work with owners of PR infected swine herds to free the herd of the disease by following one of the three basic clean up plans prepared by the Pseudorabies Committee of Livestock Conservation Institute and supported by USDA, APHIS, Veterinary services and published as State-Federal Industry Program Standards.
   1. Test and removal of positive animals.
   2. Offspring segregation, followed by phased repopulation. This method develops a PR negative herd using the offspring of sero-positive adults.
   3. Depopulation with or without repopulation.
5. Vaccination will be used only when approved by the Mississippi

State Veterinarian (the State Veterinarian will base his approval of vaccine use on the recommendation of the designated area epidemiologist).

(Adopted January 6, 1982, effective March 1, 1982.)

Handling of positive results in the Pseudorabies Herd Monitoring Program, private tests for securing a qualified herd, for show, sale or interstate movement:

1. Herds which have a single low-titer animal will be quarantined. The positive animal will be retested within 30 days. If the retest is negative, the quarantine will be released immediately. Confirmed positive results will result in routine infected herd handling.
2. Infected herds will be quarantined and animals permitted only to slaughter. Release from quarantine will be based upon the following:
   1. Entire herd permitted to slaughter and premises cleaned and disinfected under regulatory supervision. Premises may be re-populated 30 days after cleaning and disinfection. If premises are not cleaned and disinfected, premises may not be repopulated. Or
   2. Complete negative herd test at least 30 days following removal of test positive animals.

(Adopted January 6, 1982, effective March 1, 1982.)
