What is HACCP

haccp-Axion-Cotton-new

 

Hazard analysis and critical control points, or HACCP is a systematic preventive approach to food safety from biologicalchemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level. In this manner, HACCP attempts to avoid hazards rather than attempting to inspect finished products for the effects of those hazards. The HACCP system can be used at all stages of a food chain, from food production and preparation processes including packaging, distribution, etc.

Principles

  1. Conduct a hazard analysis
    Plan to determine the food safety hazards and identify the preventive measures the plan can apply to control these hazards. A food safety hazard is any biological, chemical, or physical property that may cause a food to be unsafe for human consumption.
  2. Identify critical control points
    critical control point (CCP) is a point, step, or procedure in a food manufacturing process at which control can be applied and, as a result, a food safety hazard can be prevented, eliminated, or reduced to an acceptable level.
  3. Establish critical limits for each critical control point
    A critical limit is the maximum or minimum value to which a physical, biological, or chemical hazard must be controlled at a critical control point to prevent, eliminate, or reduce that hazard to an acceptable level.
  4. Establish critical control point monitoring requirements
    Monitoring activities are necessary to ensure that the process is under control at each critical control point. In the United States, the FSIS requires that each monitoring procedure and its frequency be listed in the HACCP plan.
  5. Establish corrective actions
    These are actions to be taken when monitoring indicates a deviation from an established critical limit. The final rule requires a plant’s HACCP plan to identify the corrective actions to be taken if a critical limit is not met. Corrective actions are intended to ensure that no product is injurious to health or otherwise adulterated as a result if the deviation enters commerce.
  6. Establish procedures for ensuring the HACCP system is working as intended
    Validation ensures that the plants do what they were designed to do; that is, they are successful in ensuring the production of a safe product. Plants will be required to validate their own HACCP plans. FSIS will not approve HACCP plans in advance, but will review them for conformance with the final rule.
    Verification ensures the HACCP plan is adequate, that is, working as intended. Verification procedures may include such activities as review of HACCP plans, CCP records, critical limits and microbial sampling and analysis. FSIS is requiring that the HACCP plan include verification tasks to be performed by plant personnel. Verification tasks would also be performed by FSIS inspectors. Both FSIS and industry will undertake microbial testing as one of several verification activities.
    Verification also includes ‘validation’ – the process of finding evidence for the accuracy of the HACCP system (e.g. scientific evidence for critical limitations).
  7. Establish record keeping procedures
    The HACCP regulation requires that all plants maintain certain documents, including its hazard analysis and written HACCP plan, and records documenting the monitoring of critical control points, critical limits, verification activities, and the handling of processing deviations. Implementation involves monitoring, verifying, and validating of the daily work that is compliant with regulatory requirements in all stages all the time. The differences among those three types of work are given by Saskatchewan Agriculture and Food.

Standards

The seven HACCP principles are included in the international standard ISO 22000 FSMS 2011. This standard is a complete food safety and quality management system incorporating the elements of prerequisite programmes(GMP & SSOP), HACCP and the quality management system, which together form an organization’s Total Quality Management system.

Other standards, such as Safe Quality Food Institute’s SQF Code, also relies upon the HACCP methodology as the basis for developing and maintaining food safety (level 2) and food quality (level 3) plans and programs in concert with the fundamental prerequisites of good manufacturing practices.
