"The death toll has now risen to 303 after the 19 bodies were exhumed," Coast Regional Commissioner Rhoda Onyancha said.
Police believe most of the bodies found in a forest near the Indian Ocean town of Malindi belong to followers of Paul Nthenge Mackenzie, a taxi driver-turned-preacher who has been in police custody since April 14.
He is due to face charges of "terrorism" in the case which has rocked the east African nation.
The 50-year-old founder of the Good News International Church turned himself in on April 14 after police acting on a tip-off first entered Shakahola forest.
While starvation appears to be the main cause of death, some of the victims - including children - were strangled, beaten or suffocated, according to chief government pathologist Johansen Oduor.
Questions have been raised about how Mackenzie, a father of seven, managed to evade law enforcement despite a history of extremism and previous legal cases.
The horrific saga has stunned Kenyans and led President William Ruto to set up a commission of inquiry into the deaths and a task force to review regulations governing religious bodies.
Another pastor accused of links to Mackenzie and to the bodies found in the forest was released on bail at a court hearing.
Ezekiel Odero, a high-profile and wealthy televangelist, is being investigated on a raft of charges including murder, aiding suicide, abduction, radicalization, crimes against humanity, child cruelty, fraud and money laundering.
