Who is responsible for the overall ship sanitation program on board?

The responsibility for the overall ship sanitation program on board ultimately falls to the Commanding Officer (CO). The CO holds the highest authority on the ship and is accountable for ensuring compliance with sanitation regulations and standards set forth by naval and health authorities. This encompasses a variety of tasks, including overseeing the maintenance of hygiene in living quarters, food preparation areas, medical facilities, and waste management systems.

While the ship's doctor plays a critical role in health and sanitation by monitoring crew health and addressing any medical issues that arise, their authority is focused on health-related matters rather than the overall sanitation program. Similarly, department heads manage specific areas within their departments but do not have the overarching responsibility or authority over the entire ship's sanitation program. The ship captain is involved in various ship operations and decisions but does not assume the full scope of responsibility that lies with the CO in terms of all-around ship sanitation programs. Thus, the Commanding Officer's role is crucial in ensuring that all sanitation practices are adhered to and effectively managed.
