CHA Transmission & Drivetrain Systems 2 — Questions and Answers
Question 1: During a HACCP audit, which document best demonstrates that a CCP monitoring frequency is scientifically justified?
- Corrective action log
- HACCP plan with supporting hazard analysis data (Correct answer)
- Employee training records
- Sanitation schedule
Correct answer: HACCP plan with supporting hazard analysis data
The HACCP plan paired with the hazard analysis provides the scientific rationale for the monitoring frequency established at each CCP.
Question 2: A HACCP auditor finds that a critical limit was set based solely on customer preference rather than regulatory or scientific data. This is BEST classified as:
- A minor observation
- A critical non-conformance (Correct answer)
- An opportunity for improvement
- A prerequisite program deviation
Correct answer: A critical non-conformance
Critical limits must be based on regulatory requirements or validated scientific evidence, not customer preference; a limit lacking this basis is a critical non-conformance.
Question 3: Which of the following is the PRIMARY purpose of verification activities in a HACCP system?
- To train new employees on CCPs
- To confirm the HACCP plan is being implemented effectively (Correct answer)
- To document corrective actions taken
- To establish new critical limits
Correct answer: To confirm the HACCP plan is being implemented effectively
Verification confirms that the HACCP system is functioning as intended and that hazards are being effectively controlled.
Question 4: When reviewing CCP monitoring records, a HACCP auditor notices that temperature logs contain several entries recorded in ink that has been completely crossed out and rewritten. The BEST auditor response is to:
- Accept the records if the final values are within the critical limit
- Flag the alterations as a potential record integrity concern requiring investigation (Correct answer)
- Request that employees redo the logs
- Discard the records and ask for digital substitutes
Correct answer: Flag the alterations as a potential record integrity concern requiring investigation
Altered records must be investigated for authenticity; HACCP records must be accurate, legible, and genuine to be valid.
Question 5: An auditor discovers a food processing plant has no written procedure for what to do when a CCP falls outside its critical limit. Under HACCP principles, this is:
- Acceptable if employees know verbally what to do
- A non-conformance because a corrective action procedure is a required HACCP element (Correct answer)
- Only required for high-risk CCPs
- Addressed adequately by the sanitation SOP
Correct answer: A non-conformance because a corrective action procedure is a required HACCP element
Corrective action procedures are one of the seven HACCP principles and must be documented for every CCP.
Question 6: Which scenario BEST illustrates the concept of 'validation' in a HACCP system?
- Checking cook temperatures daily during production
- Reviewing monitoring records at the end of each shift
- Using scientific studies to confirm that 165°F destroys the target pathogen (Correct answer)
- Training employees on proper thermometer use
Correct answer: Using scientific studies to confirm that 165°F destroys the target pathogen
Validation is the process of obtaining evidence that a control measure is capable of controlling the identified hazard, typically through science or regulatory guidance.
Question 7: During a HACCP audit, an auditor wants to confirm that the hazard analysis is current. Which action is MOST appropriate?
- Review the employee handbook
- Check if the hazard analysis was re-evaluated after any process changes (Correct answer)
- Inspect the facility's pest control logs
- Verify that all employees have food handler cards
Correct answer: Check if the hazard analysis was re-evaluated after any process changes
The hazard analysis must be reviewed and updated whenever there are process changes, new ingredients, or new scientific information that could affect food safety.
