Porcine Epidemic Diarrhea (PED)

Updated February 13, 2014

In an effort to protect Wisconsin’s pork industry from the spread of Porcine Epidemic Diarrhea (PED) virus, State Veterinarian Dr. Paul McGraw has taken several actions including:
  • Banning the spring weigh-ins for fair pigs.  
  • Recommending only terminal shows for swine.

Dr. McGraw has taken these steps to minimize non-essential contact between pigs, as PED has been shown to spread rapidly among pigs, and also farm to farm. 

The ban on the spring weigh-ins will include the typical group weigh-ins, as well as traveling farm to farm to weigh and tag pigs prior to the county fairs and shows. 

Dr. McGraw also recommends only terminal swine shows, as opposed to shows allowing pigs to return to the farm of origin or travel to a location other than slaughter.  Exhibitors at non-terminal shows should be aware that if PED is found in pigs at the show, possible state actions to control the disease could include:  quarantine of all animals on the premises, and condemnation of infected pigs.  PED will also become a reportable disease, making it mandatory for veterinarians, producers and laboratories to report a positive to the State Veterinarian. 

To date, we are aware of 6 confirmed cases of PED in Wisconsin. Other states, including our border states, have seen many more, and the disease continues to spread nationally.  The PED virus causes diarrhea, vomiting and severe dehydration, especially young piglets.  Pork industry analysts estimate one to four million swine have died from PED since the outbreak began in April 2013, causing tremendous economic losses for infected farms.  

The best weapon we have for fighting the spread of PED is biosecurity. This means minimizing contact between pigs from different locations, cleaning and disinfecting anything coming in contact with pig manure, and establishing a ‘clean crossing’ or line of separation between potentially infected and clean areas.
