Hazard Analysis and Critical Control Point (HACCP) is a systematic preventive approach to food safety that addresses physical, chemical, and biological hazards throughout the food production process. Originally developed by the Pillsbury Company, NASA, and the U.S. Army Laboratories in the 1960s for space food production, HACCP has become the internationally recognized framework for food safety management. The system is built on seven core principles that provide a structured method for identifying, evaluating, and controlling hazards.
Principle 1 involves conducting a hazard analysis to identify potential hazards associated with each step of the production process. Principle 2 requires the determination of Critical Control Points (CCPs) where control can be applied and is essential to prevent or eliminate a hazard. Principle 3 establishes critical limits at each CCP — measurable parameters such as time, temperature, pH, or water activity that must be met to ensure product safety. Principle 4 specifies monitoring procedures at each CCP to ensure critical limits are consistently maintained.
Principle 5 defines corrective actions to be taken when monitoring indicates a deviation from a critical limit. Principle 6 establishes verification procedures to confirm that the HACCP system is functioning effectively, including validation of the initial plan, calibration of monitoring equipment, and periodic audits. Principle 7 requires documentation and record-keeping to provide evidence of the effective operation of the HACCP system. Together, these principles form a comprehensive and verifiable food safety management system.
Prerequisite programs form the foundation upon which a HACCP plan is built. Good Manufacturing Practices (GMPs), Good Hygiene Practices (GHPs), and Sanitation Standard Operating Procedures (SSOPs) address fundamental operational conditions that support HACCP. These include facility design and maintenance, equipment calibration, pest control, personnel hygiene, supplier control, and traceability. The Codex Alimentarius provides the international framework for HACCP implementation, while regulatory bodies such as the USDA (for meat and poultry) and FDA (for seafood, juice, and most other foods) mandate HACCP in specific sectors, with EU regulations similarly requiring HACCP-based procedures.
A multidisciplinary HACCP team approach is essential for effective implementation. The team should include individuals with expertise in food microbiology, processing, quality assurance, engineering, and production. A product description, intended use, and process flow diagram must be developed and verified on-site. HACCP plans are living documents that require reassessment whenever changes occur in ingredients, processing methods, equipment, or regulatory requirements. The hazard analysis identifies biological, chemical, and physical risks, leading to determination of critical control points. Ongoing monitoring and verification ensures the plan remains effective.
