Porcine Reproductive and Respiratory Syndrome (PRRS) and Porcine Epidemic Diarrhea Virus (PEDv) are common diseases present in pig populations. PRRS is a viral respiratory and reproductive disease which causes abortions and infertility in adult sows. PEDv is a virus which causes diarrhea in all ages of pigs but is more severe in young piglets, often times leading to death.  In an effort to reduce exposure to PRRS and PEDv, Wisconsin has recently changed the rules regarding the transportation of porcine. All pigs(with a few exceptions below) are required to be tested before moving within or in/out of Wisconsin. Below are some frequently asked questions…

What pigs have to be tested?
Any swine moving into or within Wisconsin must be tested within 90 days of movement (swine moving to slaughter or to one exhibition prior to slaughter are exempt).

What happens when I go to an in state show?
The herd of origin must test negative for PRRS/SECD within 90 days of any swine’s movement to the exhibition or show. This allows swine from jackpot shows to have one test early in the spring to travel to a number of shows throughout the season.

What happens when I go to an out of state show?
If swine originate from Wisconsin and return to Wisconsin after an exhibition or show in another state, the exhibitor must notify DATCP of the movement before returning to Wisconsin. DATCP will quarantine the swine, herd of origin, or both until a herd plan is
developed and approved.

How do I test?
● A simple way to test is the “cotton rope” test which can be done by the swine owner under the direction of an accredited veterinarian.
● Cotton rope kits are available at Lodi Veterinary Care free of charge.
● Instructions for how to collect an oral sample using the rope test are
included with the kit. Please read the instructions carefully.

● Test samples can also be collected via blood serum and swab by a
● Regardless of who collects the sample, an accredited veterinarian
must submit the sample.

How much does it cost to test for PRRS and PEDv?
● Cotton rope test kit is free of charge
● Submission fee: ~$15
● PCR testing for PRRSv and PEDv: ~$65
● Health Certificate per exhibition: ~$50 (plus call charge)

*Fees may vary based on the number of animals going to an exhibition and is at the discretion of your veterinarian.

When should I test for PRRS/PEDv?
We recommend testing at least two weeks prior to your first exhibition to allow for the return of test results and to develop a herd plan if the results are positive.

What is a herd plan?
● A herd plan is a program developed with your veterinarian and
approved by DATCP to help bring your herd back to negative status
and reduce the spread of the disease.
● A herd plan is required if any pigs test positive for either PRRS/PEDv
or if the pigs were imported into Wisconsin without a negative test
within 90 days of being imported.

Details regarding what must be done for your herd plan can be discussed with your veterinarian at the time of a positive test result for PRRS or PEDv.
