The HACCP methodology is based on 7 basic principles.
Conduct a hazard analysis. These hazards may be microbiological, chemical or physical.
Determine the critical control points. which are the places in the food production process where hazards can be controlled. A Critical Control Point is the last practical place in the process where a hazard can be eliminated.
Establish critical limits. These limits are the standards by which the potential of hazards are measured at a given Critical Control Point.
Establish a system to monitor control of the CCP.
Establish the corrective action to be taken when monitoring indicates that a particular Critical Limit is not under control.
Establish procedures for verification to confirm that the HACCP system is under control.
Establish documentation concerning all procedures and records appropriate to these principles and their application.
