CHA HACCP System Implementation & Monitoring 3

Question 1

In HACCP terminology, what distinguishes an 'operational prerequisite program (oPRP)' from a CCP?

Accepted Answer

oPRPs manage conditions that reduce hazard likelihood but are not critical control points

Answer

oPRPs (used in ISO 22000) control food safety hazards to acceptable levels but are not classified as CCPs because loss of control does not directly result in unacceptable food safety risk.

Question 2

Which of the following is a valid verification activity under a HACCP system?

Accepted Answer

Reviewing CCP monitoring records for completeness and accuracy

Answer

Reviewing monitoring records is a verification activity that confirms CCPs were monitored as required and critical limits were met.

Question 3

A HACCP auditor reviews a flow diagram for a ready-to-eat deli product. The diagram omits a rework loop where rejected product is reintroduced into the process. What risk does this omission present?

Accepted Answer

Potential hazards introduced during rework may not be identified and controlled

Answer

Omitting a rework loop means hazards reintroduced at that step were never analyzed, leaving a potential gap in hazard control.

Question 4

When validating a thermal kill step CCP, which of the following sources of information would be MOST scientifically credible?

Accepted Answer

Published peer-reviewed thermal death time studies for the target pathogen

Answer

Peer-reviewed thermal death time studies provide scientifically validated data on pathogen destruction that supports the scientific basis of a thermal kill CCP.

Question 5

A HACCP plan for a juice facility identifies pH control as a CCP for pathogen inhibition. The critical limit is pH ≤ 4.1. Which monitoring method is MOST appropriate?

Accepted Answer

Calibrated pH meter measurement with documentation

Answer

A calibrated pH meter provides accurate, objective, and documented measurements that reliably confirm the critical limit is met.
