Introduction
What Are the Symptoms of Auricularia (Wood Ear) Poisoning?
Auricularia (wood ear) is a common food known for its delicious taste and rich nutritional value. However, improper or unscientific consumption can lead to food poisoning. When wood ear is soaked for an extended period, bacteria naturally present on it may multiply extensively and produce toxins. After ingestion, affected individuals may experience symptoms such as nausea, vomiting, diarrhea, and dizziness; some may also develop pruritus (itchy skin).
Wood ear fungus (Auricularia auricula-judae) is a common food in daily life. Although it may appear unattractive, it is exceptionally rich in nutrients—far exceeding those found in most other vegetables and meats. Consequently, it is widely regarded as a popular health supplement and frequently consumed. However, improper preparation or consumption of black wood ear fungus can lead to poisoning. Below, we outline the symptoms of wood ear fungus poisoning.
What Are the Symptoms of Wood Ear Fungus Poisoning?
Wood ear fungus poisoning falls under the category of foodborne intoxication. Common clinical manifestations primarily involve gastrointestinal symptoms, including nausea, vomiting, abdominal distension, and diarrhea.
Although wood ear fungus is a commonly consumed food prized for its delicious flavor and high nutritional value, unscientific handling or preparation can cause food poisoning. When soaked for excessively long periods—particularly in warm conditions—the fungus provides an ideal environment for bacterial proliferation and toxin production. After ingestion, affected individuals may experience nausea, vomiting, diarrhea, dizziness, and—in some cases—pruritus (itching) and skin erythema or swelling. As the condition progresses, more severe symptoms such as dyspnea (difficulty breathing), convulsions, and shock may develop, potentially threatening life. If poisoning symptoms occur, simple induced vomiting may be performed as initial first aid, followed promptly by medical evaluation at a hospital for gastric lavage and symptomatic treatment.
When selecting wood ear fungus, choose high-quality specimens that are glossy, jet-black, and crisp in texture. During rehydration—especially in summer—change the soaking water frequently. Rinse dried wood ear thoroughly, then soak it in lukewarm water for an appropriate duration. Avoid prolonged soaking, as this encourages bacterial growth.
The above outlines the key symptoms and preventive considerations associated with wood ear fungus poisoning. We hope this information proves helpful.
