Ontario Pig Producer Disease Advisory -- PED and PDCoV Risks Rising This Winter

PED cases are increasing rapidly; producers and farm staff are encouraged to attend an upcoming virtual town hall to strengthen biosecurity defenses.

Porcine Epidemic Diarrhea (PED) and Porcine Deltacoronavirus (PDCoV) continue to pose significant risks to swine operations across the industry. Both viruses are highly infectious, spread easily through manure, contaminated equipment, transport vehicles, and human movement, and can have devastating financial consequences when they enter a herd.

Outbreaks of PED and PDCoV can cost farms more than $200 per sow, driven by increased mortality in piglets, production losses, and added cleaning, disinfection, and biosecurity costs. For many producers, the economic impact can linger well beyond the initial outbreak.

Winter Brings Higher Risk
Seasonality plays a major role in the spread of these viruses, with winter conditions creating an elevated risk. Cold temperatures allow viruses to survive longer in the environment, while increased movement of animals, feed deliveries, and service personnel further heighten exposure potential.

OMAFA advises that since mid December, reported cases of PED in particular have increased sharply, signaling the importance of renewed vigilance across all swine operations. Even farms with strong biosecurity protocols are encouraged to reassess procedures and ensure that every team member understands their role in disease prevention.

Prevention Is the Best Defense
There is no simple fix once a virus enters a barn. Prevention remains the most effective and economical strategy, relying on consistent biosecurity practices.  We know you have heard these recommendations before, but they are worth repeating: 

• Strict control of farm access
• Thorough cleaning and disinfection of vehicles and equipment
• Careful feed delivery management
• Clear protocols for staff and visitors
• Ongoing training and communication with all farm personnel

Education and coordination are essential, especially during high risk months. OMAFRA will be holding a Virtual PED/PDCoV Town Hall meeting on Thursday, January 29, from 12:00 noon to 1:00 pm to support producers and farm teams.

The session will focus on current disease trends, prevention strategies, and practical steps farms can take to reduce risk during the winter period. All producers, barn managers, and farm staff are strongly encouraged to attend.
