Fatal 2,4-D (ethyl ester) ingestion.

2,4-D (2,4-dichlorphenoxyacetic acid) is widely used in agriculture and forestry to destroy broad leaved weeds (herbicide). It has a moderate mammalian toxicity and human poisoning has rarely been reported except following ingestion with suicidal intent. We report two young adults who ingested it with suicidal intent, developed neurological, cardiac, hepatic and renal toxicity and died.
