Establishments are required by regulations to reassess their HACCP plans. How often must this occur?

• A. At least monthly
• B. Upon initial implementation and whenever changes are made
• C. Only when a deviation from a critical limit occurs
• D. At least once per calendar year

Answer: (D)

Reassessing a HACCP plan is required on a scheduled basis and whenever changes occur that could affect the plan, but the minimum frequency is annually. The regulations mandate that establishments review and update their HACCP plan at least once per calendar year to ensure it remains appropriate as processes, ingredients, and conditions change. So, even though you must reassess when there are changes, the least frequent legal requirement is to conduct a reassessment no less than once each year. Monthly reassessment is not required, and reassessing only at initial implementation or only after a deviation would miss the mandatory yearly check.
