The Chennai Corporation on Thursday sealed a building where food was illegally being cooked for supply in trains.
According to a press release, the kitchen of the building in Egmore was found to be in an insanitary condition. Packed food was being supplied from the house to trains such as Vaigai Express and Guruvayur Express.
Siva, the owner of the catering service, had not obtained licence from the Chennai Corporation for carrying out the trade.
Sewage was also found stagnant near the kitchen as there was no outlet.
Corporation officials conducted a raid on Thursday following a complaint from neighbours who were affected because of the insanitary conditions.
