Every time a food safety system failure occurs which was not addressed in the Hazard Analysis and HACCP plan (i.e., unforeseen hazard), the establishment must perform a HACCP reassessment:

• A. True
• B. False
• C. Not applicable
• D. Only for known hazards

Answer: (A)

HACCP plans are living documents that must be updated whenever new information or events reveal a hazard not previously addressed. If a food safety system failure occurs and it uncovers an unforeseen hazard, a HACCP reassessment is needed to determine whether the hazard is adequately controlled and to adjust the hazard analysis, critical control points, and related controls as required. This reassessment ensures that existing preventive measures still apply or that new controls, monitoring procedures, critical limits, verification activities, or recordkeeping are added to close any gaps. The goal is to maintain safe processing and protect consumers, so when an unforeseen hazard emerges, updating the plan is the proper course.
