Fungal poisoning occurs when a person ingests toxic mushrooms, which can lead to serious health issues. Some mushrooms contain harmful compounds that can damage the liver, kidneys, or other organs. Symptoms may include nausea, vomiting, abdominal pain, and confusion, often appearing hours or days after consumption. Identifying toxic mushrooms can be challenging, as many edible varieties closely resemble poisonous ones. Common toxic species include Amanita phalloides, also known as the death cap mushroom, which is responsible for the majority of fatal mushroom poisonings. Seeking immediate medical attention is crucial if fungal poisoning is suspected.
