Ramesh, a fisherman from Tharavaithoppu hamlet in Pamban, said the shells stink and people are forced to hold their nose when they walk on the road. Another serious problem faced by the locals, is worms. These creatures grow on the shells and attract flies, which are transmitters of diseases. “We want the officials to clean the shells and take steps to stop the crab export companies from dumping wastes near our hamlets,” demanded Ramesh.
