Definition: What is "Anisakiasis"?

ANISAKIASIS

Anisakiasis is a condition caused by an infection from Anisakis worms of the genus parasitic nematodes. These nematodes have a life cycle that involves marine mammals & various fishes. When fishes are infected with Anisakis, it could produce an "Anaphylactic reaction" in people sensitized to IgE (immunoglobulin) Anisakiasis usually occurs in areas where fish is consumed raw, salted or lightly pickled. The highest number of people with Anisakiasis is Japan (consuming sushi), Scandinavia (due to cod liver), South America (after eating ceviche) & Netherlands (from infected fermented herrings).

Symptoms & Signs

After a few hours of ingesting the infected larvae, people with Anisakiasis may experience nausea, vomiting & violent abdominal pain. Sometimes, the larvae can be coughed up. However, if the larvae passes the bowel, Anisakiasis sufferers may experience eosinophilic granulomatous, which may occur 1 day to 2 weeks after ingestion.

Treatment: How to Treat "Anisakiasis"?

Anisakiasis is common in humans because it is easily consumed through worms of under-processed fishes & through allergic reaction to various chemicals left by the worms on the flesh of fish. However, heating (up to 60 ░C) or freezing (below 20 ░C) can effectively kill Anisakis worms.

Diagnosis

Diagnosis of Anisakiasis is done through gastroscopic examination, wherein the 2-cm larvae are sought after & removed. A histopathologic exam of the tissues removed, biopsy or surgery can confirm Anisakiasis.
