While Ontario is experiencing new outbreaks of porcine epidemic diarrhea virus weekly, Manitoba has cut its outbreaks to only four last year after challenges in 2017, 2019 and 2021-22.
The Manitoba pork producers’ association credits a sustained focus on biocontainment and practical biosecurity.
Biosecurity is measures taken to keep diseases out of barns. Biocontainment is measures taken to prevent disease spreading inside barns.
According to Jenelle Hamblin, director of swine health fo® Manitoba Pork, the improvement reflects the success of the province’s PED elimination plan, particularly its prevention pillar.
Rather than applying a one-size-fits-all approach, farms worked closely with veterinarians to identify site-specific improvements, with particular emphasis on entry and exit protocols—how people, equipment, and materials move onto and off the farm.
A key priority, Hamblin explains, was ensuring biosecurity protocols were sustainable and practical, allowing staff to follow them consistently without adding unnecessary complexity to daily operations.
One of the most impactful shifts has been a stronger emphasis on biocontainment.
By practicing biocontainment measures every day—regardless of whether a disease is present—farms are better positioned to respond immediately if an infection does occur. Hamblin said that having biocontainment protocols already in place before disease detection significantly reduces the risk of inadvertently spreading infection within or between sites.
This proactive approach helps limit disease movement during the most critical early stages, when risks are often highest.
Hamblin said the measurable reduction in PED cases has reinforced confidence across the sector and motivated producers and staff to continue strengthening biosecurity and biocontainment practices.
The experience in Manitoba highlights how consistent, practical biosecurity—supported by industry coordination and veterinary collaboration—can deliver long-term disease control results, even for pathogens that have historically caused recurring challenges, said Manitoba Pork.
