Which statement best describes a prerequisite program in HACCP?

• A. A step outside the process that supports hazard control
• B. A step within the process where hazards are controlled
• C. A type of verification activity
• D. A corrective action plan

Answer: (A)

Prerequisite programs are foundational, broad controls that create the proper environment for preventing hazards. They sit outside any single processing step and support the entire operation, making hazard control possible through good sanitation, equipment maintenance, personal hygiene, pest control, supplier verification, training, and documented procedures. That’s why the statement describing a prerequisite program as a step outside the process that supports hazard control fits best—it captures the idea that PRPs are foundational conditions, not specific steps where a hazard is actively controlled.

The other ideas describe different elements of HACCP: a step within the process where hazards are controlled refers to a critical control point rather than a PRP; a type of verification activity would be about confirming the HACCP plan is functioning, not about establishing foundational conditions; and a corrective action plan is what you do after a deviation occurs, not the preventive environment provided by PRPs.
