A Tata Tea-owned garden faces legal action by Kaziranga National Park authorities after the Forensic Science Laboratory here confirmed the presence of pesticide in the carcass of a cattle "used as a bait' to kill a tiger at Hatikhuli tea estate in January. The director of the forensic laboratory, R.P. Gohain, today confirmed that pesticide residues were found on the cattle carcass that resulted in the death of a tiger cub in the Rongagora division of the tea estate, owned by the Tata Tea's North India Plantation Operations. Forest staff found the carcass of a Royal Bengal tiger cub. Another cub in a semi-conscious state had been found near a carcass of cattle laced with pesticides in January. The two cubs were believed to have consumed the cattle carcass, resulting in the death of one of them. The director of Kaziranga National Park, S.N. Buragohain, said a case was registered against the estate and action would be taken under the Wildlife Protection Act, 1972. The garden management, however, said they did not have anything to do with the death of the cub. A few labourers and even poachers might have been involved, it said. "Even villagers spray use pesticides to spray in paddy fields and there are many small tea growers in the area who are used to these chemicals. Why blame us directly?' the manager of the tea estate, Joydeep Singh, said.
