Step 5

Implement and monitor preferred solutions


Implementation of a PRRS control programme should be an active communication process involving all individuals who will be affected by the plan or potential change.

The key to successful implementation is a communication plan that incorporates:

  • Clearly-articulated direction for administration of the programme
  • Specific timelines for each task
  • Well-defined expectations


Programme monitoring has two components:

  • Checking that the programme is being implemented as expected. This will involve process checks as well as monitoring of vaccine storage conditions, timing of administration, injection techniques, etc.
  • Monitoring the success of the programme. This relies on monitoring of production parameters, clinical signs, and diagnostic information (see an example of a sampling-testing protocol below).

Effective monitoring should be proactive, consistent, and constant.
