Which of the following statements constitutes a design deficiency in a Food Safety System?

• A. Poor execution of programs/plans
• B. Not maintaining records to demonstrate implementation and effectiveness of programs/plans
• C. Hazards identified and preventive measures implemented
• D. Hazards (dangers) or preventative measures not identified; programs/plans are not supportive and effective; programs/plans not maintained/reassessed (not re-evaluated routinely, after failures, or upon changes)

Answer: (D)

Design deficiencies occur when the safety system is flawed at its foundation—hazards or preventive controls aren’t identified, and the programs meant to manage them aren’t supported, effective, or kept up-to-date through ongoing maintenance and re-evaluation after changes or failures. The statement that hazards or preventive measures are not identified and that programs are not supportive, effective, or maintained/reassessed captures this lack of foundational design. Without identifying hazards and building robust, regularly reviewed controls, the system cannot reliably prevent hazards.

In contrast, poor execution speaks to how well a plan is carried out rather than what was designed in the first place; failing to maintain records is a documentation or verification gap, not a design flaw; and having hazards identified with preventive measures in place indicates the design has already identified and implemented controls, so it isn’t about a design deficiency.
