Section 115.20 - Pseudorabies Quarantines

a) When pseudorabies has been diagnosed in a swine herd, such herd shall be placed under quarantine when:

1) It has been determined that there have been multiple swine deaths on the premises that are attributable to pseudorabies AND that swine are actually ill of a disease clinically diagnosed as pseudorabies; OR

2) Pseudorabies (Aujeszky's disease) has been confirmed by diagnosis by an approved laboratory; OR

3) One or more swine are positive to an official test for pseudorabies. Positive swine may be retested once. The results of the retest will be considered final.

b) Quarantined animals shall not be sold, loaned or traded except for slaughter. Such swine may be shipped to any market, except those which release swine for breeding or feeding purposes which do not have complete separation in space and usage of slaughter swine from breeding and feeding swine. Examples of markets which shall not receive such swine for slaughter are livestock auction markets which do not have complete separation in space and usage of slaughter swine from breeding and feeding swine, other markets licensed as feeder swine dealers, or order buyers and other slaughter buyers releasing swine for breeding or feeding purposes.

c) Pseudorabies quarantines shall be released when:

1) All swine on the premises have been shipped to slaughter, the premises have been cleaned and disinfected, and the premises have remained vacant for at least 30 days; OR

2) Two negative official pseudorabies tests at least 90 days apart have been obtained on a representative sample of the breeding swine in the herd 6 months of age and over not less than 30 days after the last positive animal has been shipped to slaughter. In herds of 35 animals or less, a representative sample is all or 10 animals, whichever is less. In herds of 36 to 299 animals, a representative sample is 30% or 30 animals, whichever is less. In herds of 300 animals or more, a representative sample is a minimum of 10%. A post quarantine test of a representative sample of the herd based on the above criteria shall be conducted between six and twelve months after release of quarantine; OR

3) A negative test has been made on the complete breeding herd at least 30 days after the last known exposed swine have left the premises.

4) The Department shall require additional herd tests prior to release of quarantine when epidemiologic evidence, such as, the presence of pseudorabies on neighboring farms or indications of reintroduction of infection into the herd is apparent.
