New testing required for swine on the move into and within Wisconsin

Wisconsin State Farmer

MADISON - Swine moving into and within Wisconsin will have to meet new testing requirements beginning Feb. 1 according to Wisconsin State Veterinarian Dr. Paul McGraw.

The new requirements are intended to help control the spread of two diseases: swine enteric corona virus disease, known as SECD, and porcine reproductive and respiratory syndrome, or PRRS. Both have caused significant hardship in the swine industry. Neither is a human health threat.

Swine moving into and within Wisconsin will have to meet new testing requirements beginning Feb. 1 to help control the spread of disease.

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, benefiting all producers, according to the Wisconsin Pork Association. 
The rule change will require farms with pigs to test for Porcine Reproductive and Respiratory Syndrome (PRRS) and Swine Enteric Corona Virus (SECD, which encompasses Porcine Epidemic Diarrhea Virus and Porcine Delta Coronavirus) when moving from one premise to another within Wisconsin, or for pigs coming into the state. 

Like all animals, swine entering Wisconsin must be accompanied by a certificate of veterinary inspection, or CVI, signed by a veterinarian who has examined them in the past 30 days and found them to be apparently healthy. In addition, the CVI must now include: 

  • A report showing that they came from a herd that has tested negative for the two diseases in the past 90 days.
  • A veterinarian’s statement that the animals showed no signs of either disease when they were examined.
  • A statement from the event veterinarian, if they came through an out-of-state sale or exhibition where they were mixed with swine from other herds, that all the herds tested negative and that none showed signs of either disease. 

Swine that don’t meet these requirements can enter Wisconsin with a CVI and import permit from the Department of Agriculture, Trade and Consumer Protection. However, they will be quarantined until a Wisconsin veterinarian has developed a herd plan addressing testing and biosecurity, and DATCP has approved the plan.

The rule does not apply to pigs moved directly to slaughter or to a veterinary clinic for treatment, or if they are returning from an out-of-state veterinary clinic.

Exhibitors who move swine into and out of the state for fairs or other exhibitions must notify DATCP. If their animals are potentially exposed to swine from positive herds at the events, they will be quarantined on return until they have a herd plan approved. They can get a herd plan approved before leaving the state, which may avoid a quarantine.

Swine moving within Wisconsin must now also test negative for PRRS and SECD within 90 days of movement, unless they’re going to slaughter, either directly or after a terminal fair or show.
