Seizures and death on a white river float trip. Report of water hemlock poisoning.

White water rafting is becoming more popular in the US, but many people are unprepared and may find themselves in dangerous situations without access to medical help. In addition to drowning, there is a risk of poisoning from common plants like Cicuta douglasii. This plant is toxic and can be easily mistaken for wild parsnip or carrot. Physicians and poison control centers should be aware of common poisonous plants in their area to treat cases of poisoning.
