Who must approve all sanitation rules of the board in writing?

The requirement for sanitation rules set by the board to receive written approval from the State Board of Health is rooted in ensuring public health and safety. The State Board of Health is tasked with overseeing practices that safeguard the health of the community, and as such, it has the authority to review and approve regulations that pertain to sanitation. This process helps maintain consistent standards and practices across different regions, thereby upholding the health standards necessary for the protection of citizens.

In this context, the other options may imply oversight or involvement in health-related regulations, but they do not hold the specific authority for approving sanitation rules. The Department of Health may be responsible for implementing policies but is not the approving body. The Governor's Office may offer support or influence policy through appointments but does not directly approve sanitation rules. The State Legislature can enact laws but does not engage in the approval process for specific sanitation regulations set by health boards. Thus, the requirement for approval by the State Board of Health underscores its fundamental role in public health governance.
