Pseudorabies program surveillance: which item is NOT currently part of the surveillance program?

• A. Testing of environmental samples from areas with feral swine
• B. Serology testing of swine populations
• C. Routine veterinary inspections
• D. Farm movement records

Answer: (A)

The surveillance program focuses on detecting PRV in domestic swine and tracking how the virus moves between herds. Serology testing of swine populations directly shows exposure within herds, making it a core method for identifying infection and monitoring herd health over time. Routine veterinary inspections help catch clinical signs, verify health status, and support early detection and control measures. Farm movement records are crucial for tracing where animals have come from and where they’ve moved to, which helps prevent and contain spread. Testing environmental samples from areas with feral swine isn’t part of the standard surveillance structure. Environmental sampling can be unreliable for confirming infection status in domestic herds and doesn’t provide the same actionable, herd-level information that serology, inspections, and movement records do, so resources are directed toward the latter methods.
