Passengers of the Mumbai-Howrah Duronto Express Sunday night staged protests at the Howrah station here after the discovery of a cockroach in a meal supplied on the train.
The passengers alleged that while the cockroach was found in the rice, several other food items given for lunch Sunday were either stale or of poor quality.
Some of the agitators alleged that 15 passengers were taken ill by consuming the food.
Indian Railway Catering and Tourism Corporation (IRCTC) admitted the discovery of an 'insect' in rice.
