    • Statement on the CVI that there are no clinical signs of PRRS and PEDv at the time of inspection.

    • Import permit required

      • For swine that originate from a herd that tested positive for PRRS or PEDv or that was not tested within 90 days prior to import.

        • If no testing was done, include a statement indicating no testing was done.
        • If the tests were positive, include the test type, date, and results on the CVI.
      • For micropigs being imported to a laboratory.

Reference resources on the sidebar for information on quarantines, testing, and herd plans after import.


Imported swine untested for either PRRS or PEDv will be quarantined at the Wisconsin destination premises. All swine on the premises will be placed under quarantine along with the untested imported swine. At least the untested imported swine m​ust be sampled for the missing test(s) (PRRS and/or PEDv) and the results must be approved by the Department. A herd plan is required if the test results are positive for either PRRS or PEDv. The quarantine may only be released by the Department.
