3.3 HACCP
Key Takeaways
- HACCP is a proactive, prevention-based food-safety system built on 7 principles applied in order.
- Principle 1 is hazard analysis; Principle 2 identifies critical control points (CCPs) - the steps where a hazard can be prevented, eliminated, or reduced.
- A critical limit (Principle 3) is the measurable boundary a CCP must meet, such as cooking chicken to 165 degrees F.
- Monitoring (4) checks CCPs, corrective action (5) fixes deviations, verification (6) confirms the plan works, and recordkeeping (7) documents it.
- HACCP follows the flow of food and is the core of active managerial control, which prevents hazards rather than reacting to inspection findings.
What HACCP Is and Why It Matters
HACCP stands for Hazard Analysis and Critical Control Points. It is a proactive, prevention-based system: instead of catching problems after they happen, HACCP designs safety into the process. It originated in the 1960s when the Pillsbury Company, NASA, and the U.S. Army developed it to guarantee safe food for astronauts. The exam treats it as the backbone of food protection, so know the 7 principles in order - they are sequential, and each one builds on the result of the previous step.
The Flow of Food
HACCP follows the flow of food - the path an ingredient takes through your operation: purchasing, receiving, storing, preparing, cooking, cooling, reheating, holding, and serving. Hazards (biological, chemical, physical) can enter at any step, so a HACCP plan examines every stage for each menu item. The flow is the map; HACCP is how you defend each point on the map.
The 7 HACCP Principles (In Order)
| # | Principle | What you actually do |
|---|---|---|
| 1 | Conduct a hazard analysis | Identify biological, chemical, and physical hazards in each menu item and step |
| 2 | Determine critical control points (CCPs) | Find the steps where control prevents, eliminates, or reduces a hazard to a safe level |
| 3 | Establish critical limits | Set the measurable boundary each CCP must meet (temperature, time, pH, ppm) |
| 4 | Establish monitoring procedures | Decide what to check, how, when, and who does it |
| 5 | Establish corrective actions | Plan in advance what to do when a critical limit is not met |
| 6 | Establish verification procedures | Confirm the system actually works (review records, calibrate, audit, test) |
| 7 | Establish recordkeeping and documentation | Keep logs of temperatures, monitoring, corrective actions, and verification |
A memory aid for the order: Hazards, CCPs, Critical limits, Monitor, Correct, Verify, Record. The first three define the plan; the last four operate and prove it.
A Worked Example: Chicken Salad
Walk a single recipe through the flow. Hazard analysis flags Salmonella in raw chicken. The CCPs are cooking (kill step) and cooling/cold-holding (prevents regrowth). The critical limits are cook to 165 degrees F and cool through two stages to 41 degrees F. Monitoring is probing the cooked chicken and logging cooler temperatures. The corrective action is to keep cooking if it is under 165 degrees F, or discard if cooling failed Stage 1. Verification is reviewing the logs and calibrating the thermometer weekly. Recordkeeping is the signed temperature log itself.
Critical Control Points vs. Critical Limits
These two terms are tested constantly and are easy to confuse.
- A critical control point (CCP) is a step in the process where control can be applied to prevent, eliminate, or reduce a hazard to a safe level - for example, cooking, cooling, or hot holding. Not every step is a CCP; a step is a CCP only when losing control there creates an unacceptable risk that no later step will fix. Receiving and storage are usually control points, but cooking is a CCP because it is the kill step.
- A critical limit is the measurable value the CCP must meet - for example, cooking chicken to 165 degrees F, cooling to 70 degrees F within 2 hours, or sanitizer at 50 to 100 ppm. A critical limit is always a number you can verify with a thermometer, timer, test strip, or pH meter.
Think of it this way: the CCP is the where; the critical limit is the how much.
Monitoring and Corrective Action
Monitoring is the planned, scheduled checking of each CCP - for instance, probing the chicken at the end of cooking and logging the temperature on the HACCP record. Corrective action is the predetermined response when a critical limit is missed: continue cooking the chicken until it reaches 165 degrees F, or discard a batch that failed cooling, and document what happened and what was done. Because corrective actions are decided in advance, every employee responds the same way under pressure rather than improvising.
Active Managerial Control
HACCP is the engine of active managerial control (AMC) - the FDA's term for an operation taking deliberate, ongoing steps to prevent the five CDC-identified foodborne-illness risk factors (improper holding temperatures, inadequate cooking, contaminated equipment, food from unsafe sources, and poor personal hygiene) rather than waiting for an inspector to find violations. As a CDM you build the plan, train staff, monitor records, and adjust procedures. This is the difference between a department that manages safety and one that merely reacts to citations.
HACCP vs. SOP
Do not confuse a HACCP plan with a standard operating procedure (SOP). An SOP describes how a routine task is performed for consistency - how to set up the salad station or stock the line. A HACCP plan is hazard-based and centered on CCPs and critical limits with monitoring and corrective action. SOPs are the foundation HACCP sits on, but they are not the same document, and the exam will test that distinction directly.
In a HACCP plan, the instruction "cook all poultry to an internal temperature of 165 degrees F" is an example of which element?
Which sequence correctly lists the FIRST three HACCP principles in order?
A monitoring check shows a batch of cooked chicken came off the line at 150 degrees F. The cook returns it to the oven until it reaches 165 degrees F and records the event. This response is an example of which HACCP principle?
