Mushroom poisoning
Alerts and Notices
Synopsis
The exact prevalence of mushroom poisoning fatalities is unknown but is thought to occur in the 100s each year. An increasing risk is emerging in parts of the world with a large influx of migrants, some of whom forage for food due to poor economic circumstances.
A key consideration in classifying type of mushroom poisoning has traditionally been time of onset of gastrointestinal (GI) symptoms. Generally, but not universally, a latency of less than 6 hours portends limited toxicity. Conversely, if GI symptoms occur more than 6 hours after ingestion, a more serious clinical course should be considered. However, as more poisonous mushrooms continue to be discovered, this timeline paradigm continues to be modified and is becoming less of a reliable guideline for prognostication.
