AbstractParaquat, a useful contact herbicide is now used in over 130 countries of the world, including Sri Lanka. The number of cases of accidental poisoning reported with paraquat is small, relative to instances of suicide. When a clear history is not available, accidental paraquat poisoning is sometimes difficult to diagnose. A 9-year-old boy was admitted to a peripheral hospital with a history of diarrhoea and vomiting. He later developed abdominal pain, subcutaneous emphysema and difficulty in breathing. Following transfer to a district hospital and then to a teaching hospital, poisoning with paraquat was suspected only on day 11 of the illness. On persistent questioning, on day 13 of the illness the child remembered that the day prior to the onset of illness, on his way from a shop, he felt thirsty and having found an empty bottle of Gramoxone (paraquat) on the wayside he used it to drink water from a water tank. The child died on day 17 and the histology of the lung showed typical changes of paraquat poisoning. This tragic episode emphasises the need for proper disposal of empty containers of all poisonous substances.
