CHA HACCP System Implementation & Monitoring 2 — Questions and Answers
Question 1: During HACCP implementation, what is the PRIMARY purpose of establishing monitoring procedures at a CCP?
- To document that the process is under control
- To detect loss of control and enable timely corrective actions (Correct answer)
- To satisfy regulatory inspection requirements
- To train employees on food safety
Correct answer: To detect loss of control and enable timely corrective actions
Monitoring at CCPs is designed to detect deviations from critical limits so corrective actions can be taken before unsafe food reaches consumers.
Question 2: Which of the following best describes a 'critical limit' in a HACCP system?
- A guideline that triggers retraining when exceeded
- A target value used to optimize product quality
- The maximum or minimum value to which a biological, chemical, or physical parameter must be controlled (Correct answer)
- A range set by management for operational efficiency
Correct answer: The maximum or minimum value to which a biological, chemical, or physical parameter must be controlled
A critical limit is the maximum or minimum value to which a biological, chemical, or physical parameter must be controlled at a CCP to prevent, eliminate, or reduce a food safety hazard.
Question 3: A HACCP team sets a critical limit of 165°F (74°C) for poultry cooking. An auditor finds monitoring records consistently showing 170°F. What should the auditor conclude?
- The process is out of control because temperatures exceed the limit
- The critical limit should be raised to match actual operating temperatures
- The process is operating within control; the critical limit is being met (Correct answer)
- Monitoring frequency should be reduced since temperatures are high enough
Correct answer: The process is operating within control; the critical limit is being met
Temperatures above the minimum critical limit of 165°F indicate the CCP is under control; exceeding a minimum critical limit is acceptable and safe.
Question 4: What is the MOST important characteristic of monitoring equipment used at a CCP?
- It must be the most expensive model available
- It must be calibrated and capable of detecting deviations from critical limits (Correct answer)
- It must be operated only by a HACCP-certified technician
- It must be approved by the FDA before use
Correct answer: It must be calibrated and capable of detecting deviations from critical limits
Monitoring equipment must be accurate and calibrated to ensure it reliably detects when a process deviates from a critical limit.
Question 5: Under a HACCP plan, when a deviation from a critical limit occurs, the FIRST step in the corrective action procedure should be to:
- Notify the local health department immediately
- Segregate and hold the affected product for evaluation (Correct answer)
- Retrain all employees involved in the process
- Revise the critical limit to accommodate the deviation
Correct answer: Segregate and hold the affected product for evaluation
Affected product must be identified, segregated, and held to prevent potentially unsafe food from entering commerce while an evaluation is conducted.
Question 6: Which HACCP principle specifically requires a food operation to establish procedures to verify that the HACCP system is working effectively?
- Principle 4 – Establish monitoring procedures
- Principle 5 – Establish corrective actions
- Principle 6 – Establish verification procedures (Correct answer)
- Principle 7 – Establish record-keeping procedures
Correct answer: Principle 6 – Establish verification procedures
Principle 6 requires verification activities to confirm the HACCP system is scientifically valid and operating as intended.
Question 7: A seafood processor uses a metal detector as a CCP. The HACCP plan states the detector must be checked every 30 minutes. An auditor finds checks were performed every 60 minutes. This is an example of:
- A minor deviation with no corrective action needed
- A deviation from the monitoring procedure that requires corrective action and documentation (Correct answer)
- An acceptable operational adjustment if no metal was found
- A prerequisite program failure, not a HACCP deviation
Correct answer: A deviation from the monitoring procedure that requires corrective action and documentation
Failure to follow the established monitoring frequency constitutes a deviation from the HACCP plan and requires corrective action and documentation regardless of outcome.
