NDTV has uncovered 350 violations at the Tamil Nadu manufacturing unit behind the deadly cough syrup linked to child deaths in Madhya Pradesh’s Chhindwara. The investigation reveals shocking lapses — use of a banned formula, no safety warnings, and absence of quality certification. NDTV has also accessed a 2023 government letter warning states that this formula should not be used for children under 4 years — a directive that was ignored.
