Certain mushrooms contain chemicals that are poisonous. The poisons (toxins) in these mushrooms can make you sick.
Call for emergency medical assistance (911 in most areas of the United States) if you or someone else may have eaten poisonous mushrooms, or call the poison control center for advice (1-800-222-1222 in the United States). The World Health Organization provides a world directory of poison centers.
Symptoms from eating poisonous mushrooms vary but almost always include:
Depending on the type of mushroom, you may also have other symptoms.
Mushrooms that cause symptoms quickly (within 2 hours) are less dangerous than those that cause symptoms later (after 6 hours).
With treatment, symptoms usually go away in 12 hours. You can die within a few hours if you aren't treated.
