In Nepal, an average of 50 people die each year due to the consumption of poisonous wild mushrooms. With the onset of the rainy season, various types of mushrooms begin to appear around forests, farmlands, grassy fields, and decaying wood. The practice of collecting and eating wild mushrooms in rural areas is deeply rooted in tradition. Most people gather wild mushrooms for their taste, cultural customs, and economic reasons. However, every year there are recurring incidents of people falling ill, being hospitalized, and in some cases dying after consuming toxic mushrooms. Hence, it is crucial to exercise special caution when consuming mushrooms during the rainy season.
Of the approximately 1,300 mushroom species found above ground in Nepal, 100 species have been confirmed as poisonous, while over 100 are considered edible. Some mushrooms contain toxic substances that can severely affect the liver, kidneys, nervous system, and heart. In particular, species belonging to the Amanita and Galerina genera are considered extremely lethal. The most dangerous poisonous mushrooms found in Nepal include Death Cap – Amanita phalloides, Destroying Angel – Amanita virosa, and Fly Agaric – Amanita muscaria.
How to identify poisonous mushrooms? Without laboratory testing, recognizing toxic mushrooms is not easy. However, certain general signs and characteristics can be noted. Mushrooms with excessively bright or attractive colors are more likely to be poisonous. Mushrooms that have white gills and a sac-like ring on their stems can also be deadly. Mushrooms growing on rotting wood or in moist locations may be toxic. It is important not to rely solely on local names or home-based testing methods.
Precautionary measures when consuming mushrooms include eating only mushrooms that are positively identified, paying special attention to children and the elderly, never consuming raw mushrooms, avoiding the collection of unfamiliar mushrooms, and refraining from eating mushrooms at night. Symptoms of mushroom poisoning can appear immediately or several hours later. In cases of suspected poisoning, it is essential to seek immediate medical attention, safely preserve the remaining mushrooms for identification, and avoid relying on home remedies.
Community awareness programs in rural areas, using posters and informational materials, leveraging social media, and educating children are effective strategies to prevent deaths caused by poisonous mushrooms. Dr. Mitra Pathak, head of the Botanical Research Center in Salyan under the Department of Botany, Ministry of Agriculture, Forestry and Environment, is actively conducting awareness campaigns to help people avoid mushroom poisoning.
