The total number of bird-flu hit districts in the state has gone up to 13 out of 19, despite the culling of birds being taken up on a war footing.
The teams are undertaking culling operations in West Midnapore, South 24 Parganas, Birbhum, Murshidabad, Malda, CoochBehar, Purulia and Howrah Districts.
Fifteen teams have started their culling operations in West Midnapore District. The teams are conducting the culling operations in a five kilometre radius of Chakbelcha village which falls under the Debra block of the Kharagpur sub-division, District Magistrate N S Nigam said.
"Five districts- South Dinajpur, Nadia, Burdwan and Bankura and Hooghly have completed their culling operations. In the remaining districts culling will be completed soon," he added.
West Bengal Animal Resources Development Minister Anisur Rehman said that over 15.75 lakh poultry have been culled so far out of the target of 22 lakh birds.
"Of the targeted 22 lakh, we have been able to cull nearly 15.75 lakh birds and 1.25 lakh have died. The rest of the lot will be completed by Monday," Rehman said.
