A member of staff at Lochgelly Recycling Centre first raised the alarm with police and then closed the plant after a member of the public noticed what is believed to be human remains in one of the refuge skips.
However, once forensic tests were completed, it was revealed the remains were that of an animal.
A Police Scotland spokesperson, said: “Following expert examination of the bones found it has now been confirmed that the bones are not in fact human, and are possibly from a deer.”
Simon Young, Fife Council service manager, told the Courier: “Our recycling centre at Lochgelly was closed for a short period of time on Sunday, October 27 to allow Police Scotland to investigate reports of a suspicious item in one of the bins.
“There were no suspicious items found and the centre was quickly re-opened.”
