"There were about 1,900 visceras at the post-mortem house of which about 1,300 are yet to be disposed off," district police chief Ashok Kumar Singh told PTI here on Tuesday.
"It is because of the negligence on the part of some pharmacists that the visceras and other parts could not be disposed of," he said.
He said the committee set up to probe the matter had submitted its report on Tuesday and has ruled out any foul play. Two pharmacists have been suspended on charges of negligence, he said.
Singh said the administration had asked the district Chief Medical Officer to ascertain if some of the visceras were to be sent for testing as part of physical evidence in some old cases.
Although a new post-mortem house was built in 1998, the bones, skulls and visceras used to be kept at the old one, he said. Panic had gripped people after recovery of human bones, skulls and other parts from the site of the old post-mortem house in the town.
