Read the first 7 Verification & Validation of HACCP Systems flashcards as text

  1. Which document provides the primary scientific basis for validating a thermal kill CCP for a meat product?

    Answer: Published pathogen D-value and z-value data from peer-reviewed literature

    Validation relies on scientific data such as published D-values and z-values to confirm a thermal process achieves the required log reduction of target pathogens.

  2. When a HACCP team modifies a critical limit at a CCP, what is the required next step before resuming production?

    Answer: Revalidate the HACCP plan to confirm the new limit controls the hazard

    Any change to a critical limit requires revalidation to ensure the modified limit still effectively controls the identified hazard.

  3. A HACCP auditor reviews calibration records for a thermometer used at a cooking CCP and finds calibration was last performed 14 months ago, exceeding the 6-month requirement. This is BEST classified as:

    Answer: A verification procedure non-conformance

    Overdue calibration of a monitoring instrument is a failure of the verification procedure requiring that equipment remain calibrated per schedule.

  4. In HACCP terminology, 'challenge testing' using inoculated pack studies is an example of:

    Answer: Validation of a critical control point

    Inoculated pack studies challenge the process with target organisms to scientifically confirm the CCP achieves the required hazard reduction, which is validation.

  5. Which of the following is a VERIFICATION activity in an ongoing HACCP system?

    Answer: Reviewing CCP monitoring records for completeness and correctness

    Reviewing CCP monitoring records is a verification activity that confirms the HACCP system is being implemented as planned.

  6. A facility uses pH as a CCP to control Clostridium botulinum. The validation study was completed 5 years ago. What should trigger a revalidation?

    Answer: A change in the acidulant supplier or acidification process

    A change in the acidulant supplier or process can affect the pH achieved, necessitating revalidation to confirm the hazard is still controlled.

  7. Which regulatory framework in the U.S. mandates HACCP verification activities including records review and direct observation for seafood processors?

    Answer: 21 CFR Part 123 (Seafood HACCP)

    21 CFR Part 123 specifically governs seafood HACCP and mandates verification procedures including records review and direct observation.
