Who verifies HACCP flow diagrams?

The verification of HACCP flow diagrams is primarily accomplished through a physical walk-through of the facility. This process allows trained personnel to observe and confirm that the actual operations align with the flow diagrams created for the HACCP plan. It ensures that every step in the production process is accurately represented and that there are no discrepancies between the diagram and real-life practices. This verification is crucial because it helps identify any potential hazards or areas that may require modification in the HACCP plan to ensure food safety.

While top managers and local inspectors might play roles in HACCP management and compliance, their involvement does not directly address the practical confirmation of flow diagrams with actual facility operations. Additionally, sending documents to the FDA is not a standard verification method for flow diagrams, as the FDA's role is more about regulatory oversight and compliance rather than on-the-ground verification.
