Families of the deceased have been given 21-day ultimatum from January 23, to show up at the Hospital to identify and claim the bodies or risk mass burial.
A statement from the hospital authorities said the dead included 16 of the June 3, 2015 Accra flood and fire disaster which claimed more than 150 lives.
It said only four have been identified, but their bodies have since not been claimed. They are Hellen Danso, Godspower Moregie, Hanna Quaye and Akwasi Tawiah.
“The continued storage of these bodies is causing severe congestion and affecting the efficiency of the mortuary,” it added.
The statement urged people who suspect their relatives might be dead to report to the hospital, to identify and claim their bodies, warning that “failure to do so will result in a mass burial of the bodies”.
The June 3 twin disaster was as a result of hours of downpour and an explosion at a GOIL filling station at the Kwame Nkrumah Circle in Accra, where some people were seeking refuge.
