What must occur if the next of kin cannot be reached in a timely manner?

When the next of kin cannot be reached in a timely manner, it is essential to notify the Department of Public Health. This step is crucial because the Department plays a regulatory role in overseeing the handling of deceased individuals, ensuring that the law is followed and public health concerns are addressed. The timely notification allows the Department to provide guidance on the appropriate procedures to follow, ensuring that the deceased's body is handled respectfully and legally, and that all necessary steps are taken to either facilitate the final arrangements or involve the appropriate authorities.

The other options may not adequately address the situation; for instance, cremation without consent from the next of kin would not comply with legal and ethical standards. Waiting indefinitely is impractical and could lead to complications, both legal and logistical. Involving legal authorities without notifying the Department of Public Health could also result in a lack of proper procedure and oversight, which is essential in these sensitive situations.
