Fundamentals HACCP 食物安全重點控制
HACCP = Hazard Analysis Critical Control Point
Introduction:
- HACCP system leads to the production of microbiologically safe foods by analysing the hazards of raw materials that may appear at the processing and at the consumer end;
- The HACCP system improves product safety by anticipating and preventing health hazards before they occur;
- This HACCP concept enhances consumer confidence in the food industry while motivating developing countries to build a firm food safety control system for export;
- HACCP is the major part of requirement in ISO 22000 international standard.
History of HACCP
Pillsbury/NASA – American Space Program – 1960’s to ensure food safety of Astronauts
NASA required a “zero defect” program to guarantee safety in the foods astronauts consumed in space
It’s not a zero risk system, but is designed reduce food safety hazards to minimum
The Seven HACCP Principles
- A list of steps in the process where significant hazards occur should be prepared and their preventive measures should be described.
- Hazards are categorized into three general areas: Biological, Chemical, and Physical. For the most part, biological, which includes pathogens, is the hazard that most plans are used to prevent.
- The challenge that faces the HACCP Team is to determine what are truly significant versus insignificant hazards.
- – The team must weight both risk and severity when analyzing hazards.

- – A critical control point is defined as a point, step or procedure at which control can be applied and a food safety hazard can be prevented, eliminated, or reduced to acceptable levels.
- – The differs from a control point, which is a less specific and important step in the process.
- – The selection of CCP is aided by the use of a CCP decision tree.
- – This decision tree is designed to allow the team to ask specific and logical questions to help determine, what is truly a critical control point versus a control point or something that could be handled under the GMPs (Good manufacturing practices) or SOPs (Standard operating procedures)
[/rt_accordion_style_item][rt_accordion_style_item radiant_accordiontitle=”Principle 3 : Establish Critical Limit(s)”]
- – Critical limits must be established for preventive measures associated with each identified CCP.
– Critical limits serve as the boundaries for each CCP. Examples of critical limits are preventative measures such as temperature, pH, time, moisture level, etc.
[/rt_accordion_style_item][rt_accordion_style_item radiant_accordiontitle=”Principle 4 : Establish CCP monitoring procedures”]
- Procedures must be established for using the results of monitoring to adjust the process and maintain control.
- CCP monitoring is a planned sequence of observations or measurement to assess whether a CCP is under control and to produce an accurate record for future use in verification.
- Monitoring is focused on preventing deviations (those occurrences outside the critical limits) from happening. If deviations do occur, monitoring will provide the information as to when problems occurred so that corrective action can be taken.
- Monitoring is performed best in real-time, i.e., measuring the process as it occurs rather than taking samples and sending to a laboratory.
[/rt_accordion_style_item][rt_accordion_style_item radiant_accordiontitle=”Principle 5 : Establish Corrective Actions”]
- – Make practical plans for re-dressing a CCP that has gone out of “control” in advance so that actions taken are effectively, calm and planned.
[/rt_accordion_style_item][rt_accordion_style_item radiant_accordiontitle=”Principle 6 : Establish Verification Procedures”]
- Verification is an on-going process that helps in ensuring that the HACCP plan is doing what it is supposed to do: prevent hazards from becoming a part of the food supply.
- Outside experts play an important role in giving input to the team as to ways to improve the plan.
[/rt_accordion_style_item][rt_accordion_style_item radiant_accordiontitle=”Principle 7 : Establish Documentation”]
- The approved HACCP plan and associated records must be on file at the establishment for documenting the HACCP system.
- For the most part, this may be the only part of the HACCP plan that will be audited or reviewed by customers or regulators.
Documents include
– Temperature Chart
– Cleaning Schedules
– Pest Control Records
– Equipment Maintenance Records
– Training Records
– Delivery Checkes
– Non Conformance Reports[/rt_accordion_style_item][/rt_accordion_style]
History of HACCP
The HACCP system has grown to become the universally accepted method for food safety assurance
Five Critical Considerations
Carrying out a HACCP Study
E.g.:
-18°C
Food that is properly frozen and cooked is safe. Food that is properly handled and stored in the freezer at 0°F
(-18°C) will remain safe. While freezing does not kill most bacteria, it does stop bacteria from growing.[/rt_accordion_style_item][rt_accordion_style_item radiant_accordiontitle=”Procedure 4:Establish monitoring procedures”]Implement systems to monitor the “control” status of the identified hazard
