Which publication provides guidelines for conducting an investigation into foodborne illness?

• A. Foodborne Illness Investigation Handbook
• B. Investigation Guidelines for Foodborne Illness
• C. Guidelines for Foodborne Illness Investigations
• D. Procedures to Investigate Foodborne Illness

Answer: (D)

A publication that offers a formal, step-by-step set of instructions for how to carry out an investigation is what provides practical guidelines for conducting a foodborne illness investigation. The title “Procedures to Investigate Foodborne Illness” signals a structured protocol investigators can follow, detailing who does what, what data to collect, how to analyze it, and how to report results. That explicit focus on procedures makes it the best fit for providing actionable investigation guidelines. The other titles tend to imply broader or less prescriptive resources (handbooks or general guidelines) rather than a defined workflow to execute during an investigation.
