As manure application season ramps up, one of the highest-risk activities in pork production is often hiding in plain sight.
Manure is a valuable nutrient resource—but it is also one of the most efficient vectors for disease transmission across farms.
Recent pressure from PEDv and PDCoV has reinforced a reality producers can’t afford to overlook:
👉 Biosecurity doesn’t stop at the barn door—it extends to every movement of manure.
Why Manure Handling Is a Critical Control Point
Pathogens such as PEDv, PRRSv, and Lawsonia can survive in manure and spread through multiple pathways—equipment, movement, and environmental exposure.
During agitation, pumping, and application, these risks increase.
- Aerosolization during agitation
- Contaminated boots, hoses, and vehicles
- Movement between sites
- Wildlife and insect vectors
Research continues to show a strong association between manure movement and disease spread—particularly when multiple sites or high-risk herds are involved.
👉 In practical terms, manure handling is not just a task—it’s a biosecurity event.
From Seasonal Task to System-Level Thinking
Traditionally, manure handling has been viewed as a seasonal operational job.
But the operations that perform best are shifting that mindset.
They are treating manure management as a system—with defined protocols, planning, and accountability.
That includes:
- Treating every load as a potential disease vector
- Cleaning and disinfecting equipment between sites
- Planning routes to avoid exposure to other barns
- Reducing unnecessary movement of people and equipment
- Maintaining clear separation between sites
For farms that experienced disease pressure this past season, the stakes are even higher.
👉 High viral loads in storage systems make manure handling one of the most critical risk points in the entire operation.
The Role of Communication and Coordination
Manure handling is rarely isolated to a single decision-maker.
Producers, applicators, and service providers all interact within the same system.
That makes communication essential.
Clear alignment on herd health status, cleaning protocols, and application plans can significantly reduce risk—not just for one farm, but across entire regions.
Industry tools like regional disease monitoring and mapping are reinforcing this shift—moving the industry toward more coordinated, system-level biosecurity.
Where Regulation Meets Performance
Alongside biosecurity, regulatory compliance plays an important role in how manure is managed.
In Ontario, nutrient management requirements set standards for:
- Storage capacity
- Application practices
- Recordkeeping and planning
But beyond compliance, effective manure management is also a performance issue.
Aligning nutrient application with crop needs improves soil health, reduces environmental risk, and strengthens long-term sustainability.
👉 The best operations aren’t just compliant—they’re intentional.
Swine Web Perspective
The industry has spent decades strengthening biosecurity inside the barn.
But one of the most important control points sits outside it.
👉 Manure handling is one of the most overlooked—and highest-risk—activities in modern swine production.
The operations that perform best aren’t just managing nutrients.
They are managing movement, systems, and risk—at every stage.
Because in today’s environment, the difference between stability and disruption isn’t just what happens inside the barn—
👉 It’s how well the entire system is managed beyond it.
