CHA Principles of HACCP 4

Question 1

A HACCP plan must be reassessed at least annually or whenever a change occurs. Which of the following changes would MOST critically trigger an immediate reassessment?

Accepted Answer

Introduction of a new ingredient with a different allergen profile

Answer

A new ingredient that introduces an allergen not previously present in the product significantly changes the hazard profile and requires immediate HACCP plan reassessment.

Question 2

What distinguishes a 'critical control point' from a 'control point' in HACCP terminology?

Accepted Answer

Failure at a CCP results in an unacceptable food safety risk; failure at a control point does not

Answer

A CCP is defined as a step where loss of control would result in an unacceptable food safety hazard, distinguishing it from control points where failures are manageable without safety consequences.

Question 3

Which of the following monitoring approaches at a CCP provides the MOST immediate feedback for corrective action?

Accepted Answer

Continuous online temperature monitoring with alarms

Answer

Continuous online monitoring with real-time alarms detects deviations as they occur, minimizing the amount of product potentially affected before corrective action is initiated.

Question 4

Under 21 CFR Part 120 (Juice HACCP), the regulation requires that juice processors achieve what microbial reduction through their HACCP controls?

Accepted Answer

5-log reduction of the pertinent pathogen

Answer

FDA's Juice HACCP regulation (21 CFR 120) requires a 5-log reduction of the pertinent pathogen in the finished juice.

Question 5

When validating a thermal process CCP for a low-acid canned food, which scientific tool is typically used to confirm the adequacy of the critical limit?

Accepted Answer

Challenge study with a surrogate organism

Answer

Thermal process validation for canned foods typically uses inoculated pack studies or thermal death time challenge studies with appropriate surrogate organisms to confirm the kill step is adequate.
