Hazard Analysis and Critical Control Points System (HACCP)

HACCP (Hazard Analysis and Critical Control Points – Tehlike Analizi ve Kritik Kontrol Noktaları) System is a systematic and preventive approach applied to identify, assess, and control hazards to ensure food safety. It aims to determine biological, chemical, and physical hazards throughout the food chain from production to consumption and to eliminate or reduce these hazards to acceptable levels.

Historical Development and Importance

The HACCP system was first developed in the 1960s by the United States National Aeronautics and Space Administration (NASA) to produce safe food for astronauts. In response to the inadequacies of traditional end-product testing, this system emerged by focusing on controlling hazards at every stage of the production process. Today, it has become a global standard in the food industry and plays a critical role in providing consumers with safe food and preventing foodborne illnesses. It is recognized by international authorities and national regulations as either mandatory or recommended practice for food businesses.

HACCP Principles

The HACCP system is based on seven fundamental principles:

1. Conduct a Hazard Analysis: Identifying potential biological (microbiological), chemical (pesticide residues, cleaning agents, etc.), and physical (glass fragments, metal pieces, etc.) hazards in the food chain and evaluating them according to their severity and likelihood.
2. Determine Critical Control Points (CCPs): Identifying the process steps at which control can be applied to prevent, eliminate, or reduce identified hazards to acceptable levels.
3. Establish Critical Limits: Defining measurable criteria (such as temperature, pH, time, etc.) that distinguish between acceptable and unacceptable conditions for each CCP.
4. Establish a Monitoring System: Defining continuous or periodic observation and measurement activities to verify compliance with critical limits at CCPs.
5. Establish Corrective Actions: Defining the actions to be taken when monitoring indicates that a critical limit has been exceeded, to ensure product safety and correct deviations in the system.
6. Establish Verification Procedures: Conducting periodic reviews, analyses, and audits to confirm that the HACCP system is functioning effectively and achieving its intended objectives.
7. Establish Documentation and Record Keeping: Creating a comprehensive record-keeping system that includes all stages of the HACCP plan, hazard analyses, CCPs, critical limits, monitoring records, corrective actions, and verification results.

Prerequisite Programs (PRPs) in the HACCP System

Prerequisite programs that provide basic hygiene and sanitation conditions are vital for the effective implementation of the HACCP system. These programs establish a solid foundation upon which the HACCP plan is built and help control general food safety risks. Major prerequisite programs include Good Manufacturing Practices (GMP), which aim to create a hygienic production environment and processes, and Good Hygiene Practices (GHP), which focus on basic issues such as personnel hygiene, toilet facilities, and handwashing. Sanitation standards have been established for the regular cleaning and disinfection of facilities and equipment. Pest control encompasses measures to prevent pest entry and breeding in food production areas. Waste management ensures food safety by properly collecting, storing, and disposing of waste generated during production. Cross-contamination control, another critical aspect of the production process, aims to minimize the risk of contamination between raw materials, semi-finished products, and final products. Effective implementation of these processes requires significant emphasis on staff training; workers are regularly informed about food safety and hygiene. Supplier control involves monitoring risky raw materials to ensure their reliability. Finally, regular maintenance and calibration of equipment along with recall procedures protect consumer health by enabling rapid withdrawal of products from the market in case of potential safety issues.

Applications of HACCP in Different Food Sectors

The HACCP system can be adapted to various areas of the food industry.

Application of HACCP in Ready-Meal Establishments

Ready-meal establishments pose high food safety risks due to the numerous stages involved in production to service and their role as mass consumption venues. In such establishments, the HACCP system controls hazards throughout all processes, from acceptance of raw materials to storage, pre-preparation, cooking, cooling, reheating, portioning, and serving. Particularly critical elements include separation of raw and cooked products, temperature control, prevention of cross-contamination, and personnel hygiene.

Application of HACCP in Milk and Dairy Products

Milk and dairy products require special attention for food safety due to their favorable structure for microbial growth. HACCP is applied at stages including milk collection, storage, pasteurization/sterilization, fermentation (yogurt, cheese), packaging, and distribution. Parameters such as pasteurization temperature and time, storage temperatures, pH levels, and microbiological load are identified as CCPs. This ensures the microbiological quality and shelf life of the products.
