Acute human Glufosinate-containing herbicide poisoning

AbstractBackground. Glufosinate-containing herbicides are commonly used worldwide. Data on acute human glufosinate poisoning however remain scarce. Methods. We retrospectively reviewed the medical records of all glufosinate poisoned cases reported to the Taiwan National Poison Control Center and two medical centers in Taiwan from August 1993 through February 2010. Their demographic and clinical data were then analyzed to identify potential predictors of severe effects following acute glufosinate poisoning. Results. One hundred and thirty-one patients, including 115 oral and 16 non-oral exposures, were eligible for final analysis. Among patients with oral exposure, 25 were asymptomatic, while the others developed gastrointestinal, neurological, cardiovascular, and/or respiratory manifestations. Seven patients (6.1%) died following deliberate glufosinate ingestion. The median dose of glufosinate ingestion was 30.4 grams (interquartile range 18.5–45.6 grams) in the severe/fatal group compared to 6.8 grams (i...
