Overview
- Tamil Nadu officials say a Coldrif cough syrup batch contained diethylene glycol, a toxic industrial chemical linked to acute kidney failure in children.
- Sresan bought 50 kg of propylene glycol on March 25 via Sunrise Biotech, which sourced it the same day from Jinkushal Aroma, according to suppliers and a state report.
- Both intermediaries lacked required drug licences and acknowledged breaking seals and repackaging the solvent before delivery to Sresan.
- State inspections found hundreds of critical and major violations at Sresan’s plant; the firm’s licence has been revoked and founder G. Ranganathan is in custody.
- Federal and state regulators report stepped-up facility inspections and a review of paediatric cough-syrup use as they work to determine how DEG entered the supply chain.
