CHA Transmission & Drivetrain Systems 3 — Questions and Answers
Question 1: Which of the following BEST describes the role of a prerequisite program (PRP) in relation to HACCP?
- PRPs replace the need for CCPs in low-risk facilities
- PRPs provide the foundation of basic conditions needed for HACCP to function effectively (Correct answer)
- PRPs are optional enhancements for ISO-certified facilities
- PRPs document corrective actions taken at CCPs
Correct answer: PRPs provide the foundation of basic conditions needed for HACCP to function effectively
Prerequisite programs establish and maintain the basic environmental and operating conditions necessary for HACCP to succeed.
Question 2: A HACCP auditor is evaluating a metal detection CCP. The monitoring procedure requires checking the detector every 30 minutes. The auditor finds checks recorded every 60 minutes. This represents:
- A deviation from the monitoring procedure requiring a corrective action (Correct answer)
- An acceptable practice if no rejects were found
- An improvement in efficiency
- A change in critical limit
Correct answer: A deviation from the monitoring procedure requiring a corrective action
Monitoring must occur at the frequency specified in the HACCP plan; any deviation is a non-conformance that requires a corrective action.
Question 3: When conducting a HACCP audit, which of the following is the MOST reliable evidence that employees understand their CCP responsibilities?
- Posted HACCP charts near workstations
- Direct observation of employees correctly performing monitoring procedures (Correct answer)
- Signed training attendance sheets
- Presence of a HACCP manual in the break room
Correct answer: Direct observation of employees correctly performing monitoring procedures
Observing employees actively and correctly performing their monitoring duties is the strongest evidence of true competency.
Question 4: A facility uses a pasteurization step as a CCP for pathogen reduction. The critical limit is 72°C for 15 seconds. Which type of hazard is this CCP primarily controlling?
- Chemical hazard
- Physical hazard
- Biological hazard (Correct answer)
- Radiological hazard
Correct answer: Biological hazard
Pasteurization time-temperature combinations are designed to inactivate pathogenic microorganisms, which are biological hazards.
Question 5: Under HACCP, 'monitoring' is BEST defined as:
- A quarterly review of the entire HACCP plan
- A planned sequence of observations or measurements to assess whether a CCP is under control (Correct answer)
- The process of retesting product that failed a critical limit
- An annual third-party audit of food safety practices
Correct answer: A planned sequence of observations or measurements to assess whether a CCP is under control
Monitoring involves conducting planned measurements or observations at a CCP to ensure the process stays within critical limits.
Question 6: An auditor reviews a HACCP team roster and finds it includes only quality assurance staff. This is BEST identified as:
- Acceptable because QA is responsible for food safety
- A potential weakness because the HACCP team should be multidisciplinary (Correct answer)
- A strength due to focused expertise
- A prerequisite program issue, not a HACCP issue
Correct answer: A potential weakness because the HACCP team should be multidisciplinary
The HACCP team should include individuals with diverse expertise (production, engineering, microbiology, etc.) to ensure a comprehensive hazard analysis.
Question 7: Which record type would a HACCP auditor review to confirm that an out-of-control CCP event was properly handled?
- Supplier certification file
- Corrective action record (Correct answer)
- Sanitation pre-operational checklist
- Employee training certificate
Correct answer: Corrective action record
Corrective action records document what was done when a CCP deviation occurred, including disposition of affected product.
