Rule Summary

Swine moving into and within Wisconsin now have to meet new testing requirements that are intended to help control the spread of two diseases: porcine epidemic diarrhea virus (PEDv), and porcine reproductive and respiratory syndrome (PRRS).

*Note – the initial rule language also required testing for Porcine delta coronavirus (PDCoV), but that requirement was eliminated on March 27, 2018.

The goal of the rule change is to control and reduce prevalence of PRRS and SECD in the state, and to prevent spread on positive sites. A 2016 Pork Checkoff study indicated that PRRS continues to be a major drag on the U.S. pork industry – costing $580 million per year. Due to lower pig density within the state, Wisconsin has a fairly high herd health status. This rule could help improve the health of Wisconsin pigs, benefitting all producers.

The rule change requires farms with pigs to test for Porcine Reproductive and Respiratory Syndrome and Porcine Epidemic Diarrhea Virus when moving from one premise to another within Wisconsin, or for pigs coming into the state. Untested pigs may still enter Wisconsin but will be quarantined on the Wisconsin premise until a herd plan is established. The rule does not apply to pigs moved directly to slaughter.

Testing Reimbursement Program

The Wisconsin Pork Association is offering $25 grants to pork producers to help offset costs of testing for Porcine Reproductive and Respiratory Syndrome and Swine Enteric Coronavirus Disease.

The following requirements and stipulations apply:

  • Producer must complete and mail reimbursement form by December 1, 2020.
  • Reimbursement form must include documentation showing proof of test completion
    • Proof of test can include a dated copy of a veterinary clinic bill that shows a line item for PRRS/SECD testing or a dated copy of a test report from a veterinary diagnostic lab (test results can be blacked out; proof of testing completion is all that is required for reimbursement).
