By implementing strict on-farm biosecurity protocols, pork producers can prevent PED infection in their pigs. This virus is not a risk to human health or other animals. It is not a food safety risk.

Clinical Signs

  • Sudden onset of watery diarrhea +/- vomiting in all ages of pigs
  • High mortality in piglets

If you suspect that your pigs may be infected with PED virus, contact your veterinarian immediately. He or she will provide strategies to help you to manage the disease. Be vigilant and watch for early signs of scouring.

On-Farm Biosecurity

Biosecurity procedures need to become routine business practices. Implementing strict on-farm biosecurity protocols can prevent PED from infecting your pigs.

Transportation Biosecurity

PED virus is highly infectious and can be easily spread to farms through contaminated trailers. You should ensure that only washed and disinfected trailers come on to your farm to pick up or deliver live animals.

PED Prevention at Provincial and Federal Processors

Abattoir contamination can result in the transmission of PED virus to farms from livestock trailers that have been at those facilities. Processors need to be aware of which suppliers have infected pigs so that they can take precautions to prevent their facility from becoming a source of the virus to other farms.

Euthanasia and Deadstock

While older pigs can recover from PED, the virus is fatal to nursing piglets. Producers with PED infected deadstock should work with their deadstock collector to minimize the risks of transmission or consider on-farm disposal alternatives.
