Summary
This study reports the first human anisakiasis case in China, caused by ingesting Anisakis larvae from raw fish. Prompt diagnosis and removal of the parasite resolved the patient's severe gastrointestinal symptoms.
Area of Science:
- Parasitology
- Gastroenterology
- Infectious Diseases
Background:
- Anisakiasis is a foodborne parasitic zoonosis.
- It results from consuming raw or undercooked fish contaminated with Anisakis or Pseudoterranova nematode larvae.
- Human infection is rare in China.
Observation:
- A 56-year-old male in Dalian presented with vomiting, abdominal distension, and diarrhea.
- Gastroendoscopy revealed a parasite in the stomach.
- Gastroscope-assisted surgery successfully removed the Anisakis L3 larva.
Findings:
- The removed parasite was identified as Anisakis L3 larvae.
- Post-removal, the patient's inflammatory symptoms resolved.
- Morphological characteristics of the Anisakis L3 larvae are described.
Implications:
- This is the first documented clinical case of human anisakiasis in China.
- Anisakiasis should be considered in differential diagnoses for patients with relevant symptoms and raw fish consumption history.
- Highlights the importance of food safety regarding raw seafood consumption.
