Which phase of the sanitary survey focuses on reviewing prior documentation such as old plans and previous sampling results?

• A. Post-Survey Report
• B. On-Site Survey
• C. Sanitary Audit
• D. Pre-Survey

Answer: (D)

The pre-survey phase centers on planning and reviewing existing records. Before stepping foot on site, investigators study prior documentation—old plans, previous sampling results, historical performance, and past findings—to understand the system’s baseline, identify areas of concern, and shape a focused survey plan. This preparation helps target inspections and sampling where they’re most needed, anticipate potential problems, and ensure the on-site work is efficient and informed. In contrast, the on-site survey is the actual field inspection, the post-survey documents and communicates findings, and the sanitary audit assesses ongoing compliance with sanitary practices.
