Update on PRRS/SECD Rule Changes

Following public hearings and comment period earlier this spring, the proposed Porcine Reproductive and Respiratory Syndrome (PRRS) and Swine Enteric Coronavirus Disease (SECD) rule that establishes testing requirements for commercial swine imported into or moving within Wisconsin has been updated.

Changes were made to the draft rule as a result of comments received. Those changes include:

  • Number of swine to be tested has been changed, establishing a testing threshold of 150 swine (rather than 30.)
  • In addition to sampling by rope or blood, the rule clarifies that other sampling methods may be used if approved by the Department.
  • Requirements for “breeder” swine have been changed to pertain to all commercial swine imported to Wisconsin.
  • Testing requirements for PEDV has been changed to testing for SECD, as SECD is a more inclusive disease term that includes PEDv.

Generally, the goals of the rule are to control and reduce prevalence of PRRS and SECD, and to prevent spread on positive sites.  The draft rule requires a report of a negative PRRS and SECD test from the swine’s herd of origin within 90 days prior to movement into the state. In addition, the swine moving from one premise to another premise within the state must also have a negative herd test within 90 days prior to movement. In either case, if pigs test positive, the pigs, herd or both would be quarantined until a herd plan is developed by the producer and his veterinarian and approved by the Wisconsin Department of Agriculture. The goal of the herd plan is to bring the herd to negative PRRS and SECD status and limit the spread of the disease. Template herd plans will be available for producers and veterinarians.

A 2016 Pork Checkoff study indicated that PRRS continues to have a major economic impact on the U.S. pork industry – costing $580 million per year. Similar to PRRS, SECD – which includes PEDv and Delta Coronavirus – has a substantial economic burden given that it is highly infectious, resulting in significant morbidity and mortality in piglets.

The anticipated effective date of the rule establishing the new testing requirements will be sometime during the spring of 2018. However, this may change depending on the rule process.
