Pseudorabies Quarantine Requirements

PURPOSE: This rule establishes a method of control for animals exposed to or infected with pseudorabies. (1) Definitions. (A) Circle testing shall mean all swine units, including feedlots, within a two (2)-mile radius of the infected premises. (B) Contact/adjacent herds shall mean herds sharing common premises, herds disclosed by epidemiological traces, herds within two (2) miles or herds containing purchases from or exchanges with quarantined infected herd. (C) Herd shall mean all swine of any age under common ownership or supervision whether geographically separated or not. (D) Individual herd plan shall mean a system for eliminating pseudorabies from the quarantine herd, written specifically for each herd and approved by the state veterinarian or his/her designee that minimizes spread to other herds and prevents reinfection after the herd has become free of pseudorabies. The individual herd plan shall be developed by the owner, the owner’s veterinarian, and the district veterinarian. (2) Requirements for Quarantine Release. Quarantine shall be released according to current State-Federal-Industry Program Standards. (3) Individual Herd Cleanup Plan. (A) An individual herd cleanup plan shall be developed with every producer who has a pseudorabies-infected herd. (B) Minimum requirements of the individual herd cleanup plan are— 1. Test swine consistent with sound eradication principles; 2. Proper disposition of dead animals; 3. Complete epidemiological investigations. All contact/ adjacent exposed herds shall be investigated and tested (circle tested), either a complete test of all breeding swine or the test of an official random sample; 4. Animals to move only into slaughter channels or to approved quarantined feedlots; and 5. Progression towards elimination of the infection from the herd as determined by the state veterinarian or designee. (C) The individual herd plan requirement shall be met except when the official pseudorabies epidemiologist, state veterinarian or designee authorizes modification of the plan consistent with sound eradication principles. Owners must provide for the handling of their swine and testing will be at owner’s expense. AUTHORITY: section 267.645, RSMo Supp. 1994.* Original rule filed Nov. 15, 1988, effective March 26, 1989.
