CHA Safety Systems & Standards 3

Question 1

Which Codex Alimentarius document serves as the foundational international reference for HACCP system implementation?

Accepted Answer

CAC/RCP 1-1969 (Rev. 4-2003)

Answer

CAC/RCP 1-1969 (Rev. 4-2003), the General Principles of Food Hygiene, contains Annex on HACCP and is the primary Codex HACCP reference.

Question 2

An auditor discovers that a facility's HACCP plan lists pasteurization as a CCP but has no written procedure for what to do when the pasteurizer malfunctions mid-run. Which HACCP principle is most directly violated?

Accepted Answer

Principle 5 – Establish Corrective Actions

Answer

Principle 5 requires that corrective actions be pre-established for each CCP to address deviations when they occur.

Question 3

Which of the following best describes the role of an 'operational prerequisite program' (oPRP) as defined in ISO 22000?

Accepted Answer

A PRP identified as essential to control a food safety hazard but managed with action criteria rather than critical limits

Answer

An oPRP controls significant food safety hazards using action criteria rather than the strict critical limits applied at CCPs.

Question 4

During an internal audit, records show that the temperature log for a walk-in cooler has entries recorded every 4 hours but the HACCP plan specifies continuous monitoring. What type of finding should this be classified as?

Accepted Answer

Nonconformance, because monitoring frequency deviates from the approved plan

Answer

Deviating from the approved monitoring frequency specified in the HACCP plan constitutes a nonconformance regardless of outcome.

Question 5

A food manufacturer's validation study for a thermal kill step should primarily demonstrate that the process achieves:

Accepted Answer

The required log reduction of the target pathogen under worst-case conditions

Answer

Validation must prove the CCP achieves the intended lethality against the relevant target pathogen under worst-case processing conditions.
