Kolkata/Puri:  Four passengers onboard the Puri-Sealdah Duronto Express allegedly fell ill after eating "undercooked" chicken, a railway official said. The authorities have since decided to suspend the vendor's licence.

The train departs from Puri station in Odisha at 7.45 PM on Tuesday, Thursday and Saturday and reach Sealdah in West Bengal at around 4 AM.

The Indian Railway Catering and Tourism Corporation -- which deals with catering, tourism and online ticketing of Indian Railways -- said that they have decided to discontinue with the service of the third-party vendor responsible for serving food on the train and will levy a hefty fine on him.

"Around four passengers were served undercooked chicken onboard the Puri-Sealdah Duronto Express on Saturday night. The passengers complained of uneasiness while a teenager fell ill after eating food," IRCTC General Manager Debasish Chandra said.

"We have decided to cancel the licence of vendor Krishna Enterprise and also impose a hefty fine," he said.

"Passengers are safe and sound. We are internally investigating the matter," the official added. (With IANS Inputs)
