A human tongue has been served up in a hospital canteen's chicken risotto — and bosses reckon it was accidentally dropped into the food by a doctor.

Slovenian officials are investigating after a doctor complained about a strange piece of meat on his plate.

Ananova.com revealed the doctor insisted it was not chicken and after some intense bickering it was sent away for tests — and found to be part of a human tongue.

Inspectors have closed the canteen in Izola, southern Slovenia, to review hygiene standards.

Bosses believe a doctor could have unwittingly dropped the tongue in the food after treating a patient.

A hospital spokesman insisted: "I can say clearly that we have never used patients' parts in any of our dishes."
