Fresh cases of bird flu have been confirmed in a West Bengal district, almost a month after officials expressed hope that the avian flu had been finally controlled with the culling of around four million birds. "We received confirmation on Saturday of bird flu in two villages of Murshidabad district. The two villages are Nayamukundapur in Raghunathgunj Block II and Dohapara village in Murshidabad-Jiagunj block,' Murshidabad district magistrate Subir Bhadra said. The two areas - where about 900 poultry birds died in the past week - are about 300 km from here. Bhadra said the samples that were recently sent to the National Animal Research Laboratory in Bhopal from the two villages had tested positive. He said about 60 rapid response teams would start culling chickens and ducks in affected areas soon. West Bengal animal resource development Minister Anisur Rahman confirmed the outbreak of flu again.
