Abstract
- Some carnivorous gastropods have heat stable tetramine toxins in their salivary glands. This toxin is an autonomic ganglionic blocking agent that enables them to catch the prey easily by paralyzing their targets. Acute tetramine toxin poisoning in humans from eating whelks has been well described based on numerous cases, but is rare in Korea. Symptoms of tetramine poisoning include eyeball pain, blurred vision, headache, dizziness, muscular twitching, tingling of hands and feet, weakness, paralysis and sometimes collapse. Gastrointestinal symptoms, such as abdominal pain, nausea, and vomiting can also occur. However, intoxication is self-limiting and patients will usually recover in about 24 hours. Herein, we report 2 cases of tetramine poisoning after ingestion of Buccinum striatissinum as meat and soup.
