The entity responsible for effectively observing and controlling all food establishments on the premises and for each separately operated establishment on the premises is:

• A. Food Service Officer
• B. Leading Food Management Cook
• C. Preventive Medicine Authority
• D. Public Health Officer

Answer: (C)

The key idea here is who has official oversight to observe and regulate every food operation on a single site, including each outlet that is separately operated. The Preventive Medicine Authority is the entity with the legal mandate to monitor sanitation, enforce compliance, license establishments, and coordinate actions across all food outlets on the premises. This means they can see the big picture for the entire site and also address the needs of each individual operation within it, ensuring consistent food-safety practices and rapid response to any health or safety issues. A Food Service Officer typically runs a single outlet, not the whole site; a Leading Food Management Cook is focused on kitchen operations rather than regulatory oversight; a Public Health Officer may deal with broader public health concerns, but the question’s scope is best matched by the Preventive Medicine Authority, which has the overarching authority to observe and control all food establishments on the premises.
