BHOPAL: MP SIT probing Coldrif tragedy that claimed lives of 23 kids from state took Ranganathan Govindan (75) – owner of TN-based Sresan Pharmaceuticals, which manufactured the toxic cough syrup – to his factory in TN’s Kanchipuram Sunday for an on-site inspection, reports P Naveen.The factory, sealed by TN drug control department, will now come under a joint forensic and regulatory examination to determine how banned industrial-grade DEG found its way into the cough syrup’s formulation – whether through deliberate substitution, a technical fault, or procedural negligence. The 12-member SIT will inspect the factory’s automation systems, verify machine logs, review batch production records to trace the precise stage at which contamination occurred. Technical experts will analyse mixing, bottling, and quality control processes to determine if the toxic chemical was introduced during production or through adulterated raw materials. Meanwhile, Kamla Nath, Congress member and ex-MP from Chhindwara, Sunday blamed govt for the tragedy.
