<h1>Drug regulator orders immediate halt and stock freeze of Coldrif syrup batch after diethylene glycol-linked child deaths</h1> A state drug regulatory authority has ordered an immediate halt to sale and use of a specific Coldrif syrup batch after another state's testing found the batch adulterated with diethylene glycol, a toxic solvent, and linked ingestion to multiple child deaths from suspected renal failure. Regulators directed inspectors to alert retailers, wholesalers and hospitals to freeze stock, report any possession to drugs control authorities, and are coordinating inter-state tracing of distribution. The actions signal potential administrative enforcement, product recalls, criminal investigation into adulteration and civil liability exposure for the manufacturer and distributors.
