County Public Health Officer, George Gachomba, has urged residents to help trace and identify the corpses and collect them before the notice expires.
He noted that the bodies are now decomposing and are causing congestion in the mortuary and the county is incurring huge costs in preserving them.
In the notice issued a week ago, Gachomba warned that the government will dispose off the bodies in a mass grave at Nakuru South cemetery should the owners fail to show up and collect them within the notice period.
The County has exhausted all the available mechanisms to trace their next of kin without success and this is the last resort before the bodies can be disposed in a mass grave.
The department has released a list of the bodies indicating the scenes of crime and nature of death, as well as escort contacts to assist in tracing next of kin.
