Hazard Analysis involves identifying potential physical hazards that could occur at each stage of the food handling process, from receiving raw materials to serving the final product. This requires a detailed assessment of equipment, procedures, and the overall environment.

Critical Control Points (CCPs) are points in the process where control can be applied and is essential to prevent or eliminate a physical hazard or reduce it to an acceptable level. Identifying CCPs is crucial; they represent the key intervention points.

Establishing Critical Limits defines the maximum or minimum value to which a physical, chemical, or biological hazard must be controlled at a CCP to prevent, eliminate, or reduce to an acceptable level the occurrence of the identified food safety hazard. This might involve setting limits on the size of metal fragments detectable by a metal detector.

Monitoring Procedures involve establishing a system to regularly observe and measure the CCP relative to its established critical limits. Monitoring might involve visual inspections for glass shards or regular checks of metal detector functionality.

Corrective Actions are the procedures to be followed when monitoring indicates a deviation from a critical limit. These actions should address the root cause of the problem and prevent recurrence.

Verification Procedures involve activities, other than monitoring, that determine the validity of the HACCP plan and confirm that the system is operating according to the plan. Verification activities include reviewing records, conducting independent checks, and validating the effectiveness of control measures.

Record-Keeping and Documentation are essential for demonstrating the effectiveness of the HACCP system and for providing evidence of compliance with regulations. Detailed records of hazard analysis, CCPs, critical limits, monitoring activities, corrective actions, and verification procedures are crucial.

Identifying Critical Control Points for Physical Hazard Mitigation

Identifying CCPs is a pivotal step in implementing a HACCP plan for physical hazards. These points are specific locations or steps in the food handling process where control can be applied to prevent, eliminate, or reduce the hazard to an acceptable level.
