Eliminating PEDv/PDCOV reduces overall disease pressure on our herds, improves herd productivity, and improves the competitiveness and economic viability of the Ontario swine industry. Going through this process will also help us develop and improve tools to support the control and elimination of any disease of significance to the hog industry, not just PEDv/PDCOV. This will improve our long-term disease response capacity and industry sustainability.

When a positive test is found, producers work with their veterinarian on biosecurity and sanitation protocols to contain and control PEDv/PDCOV in the herd and work towards elimination. See the PEDvPDCOV Process & Notification Timeline and Understanding the PEDPDCOV Control and Elimination Process in Ontario fact sheets for more information.

Yes, though delaying as long as possible (up to 4-6 weeks) is recommended to limit movement of highly shedding pigs. Your producer may require segregated receiving to reduce risk.

Producers can resume regular hog shipments once a PEDv/PDCOV negative site status is confirmed and communicated to their processor partners.

The risk from trucks returning to Ontario from the U.S cannot be completely eliminated at this time. All returning trucks and trailers should be washed, disinfected, and dried/baked before hauling another load. 

Should PEDv/PDCOV be confirmed, a PEDv/PDCOV elimination plan will be implemented for that specific farm. On-going surveillance will identify where extra cleaning and disinfection may be needed at industry contact points.

The goal is PEDv/PDCOV elimination from all Ontario farm sites with an effective response plan in place in case of any subsequent breaks. Next steps will include further work to reduce PEDv/PDCOV transmissions risks associated with cull pigs and assembly as well as reducing U.S. contact risks. All of this work will continue our efforts to improve our swine health system in Ontario.

Most new cases of PED/vPDCOV are linked to biosecurity lapses, either during a transport event or while accessing the barn. Most likely cause counts can be viewed on the SHO PED/PDCOV tracking map.

All known current cases are displayed on the SHO PED/PDCOV tracking map. Producers wanting more detailed information can access that by joining the SHARC platform.

• Can affect all types of pigs, resulting in dehydration, vomiting and diarrhea (symptoms of PEDv may be severe in very young piglets to very mild/non-existent in finishing pigs; symptoms of PDCoV are milder)
• Primarily transmitted through feces and direct contact between infected and non-infected animals
• Diagnosis made via PCR testing; symptoms are common to other gastroenteric diseases

• PEDv: Mortality rates for piglets up to 10 days of age can be up to 100%, dropping to less than 10% for piglets older than 10 days and less than 5% for adult and finishing pigs; infected pigs that survive generally recover within 7-10 days

• PDCoV: Mortality can be elevated, particularly in piglets <14 days old (though generally lower than PED mortality rates); older pigs will normally recover

• Prevented by proper biosecurity practices (particularly controlling exposure to trailers returning from infected sites)
• Vaccines can be used for PEDv if available to reduce clinical signs and manage an elimination but are not recommended for prevention only
• No specific treatments available outside of mitigating the effects of dehydration by ensuring plentiful clean water is available at all times
• Depopulation, cleaning and disinfection of affected facilities is typically recommended

• This disease is only infectious to swine and poses no threat to humans
• Pork products from PEDv affected herds are safe to eat
