Statement: After eating sweets served at a community meal, many local residents fell ill and were admitted to the nearby hospital. Courses of Action: I. Immediately arrest everyone who prepared the sweets. II. Shift serious cases to higher-level hospitals without delay. III. Food & Drug Authority should investigate, identify the cause, and take action.

Introduction / Context:
Food-borne outbreaks require simultaneous clinical management and epidemiological investigation. Actions must be lawful and evidence-based.

Given Data / Assumptions:

• Cluster of illness linked temporally to sweets at a community meal.
• Patients are already hospitalized locally.

Concept / Approach:
Stabilize patients and transfer severe cases (II). Conduct outbreak investigation (III): sample collection (food, water, stool), trace ingredients, check hygiene, and issue recalls/closures as warranted. Blanket immediate arrests (I) without facts violate due process.

Step-by-Step Solution:
1) Triage and refer critical patients (II).2) Initiate F&D investigation; preserve evidence; interview food handlers (III).3) Communicate risk to the public and manage exposure.

Verification / Alternative check:
Public-health protocols emphasize care + investigation before culpability decisions.

Why Other Options Are Wrong:
I presumes guilt prematurely; “All” inherits this flaw; single-option answers ignore the dual need.

Common Pitfalls:
Delays in sample collection reduce detectability.

Final Answer:
Both II and III follow.
