What is the primary symptom of Anisakis infection?

The primary symptom of Anisakis infection, which is caused by consuming raw or undercooked fish infected with the larvae of the Anisakis parasite, is indeed a tingling sensation in the throat. This symptom may occur because the larvae can attach themselves to the lining of the gastrointestinal tract, leading to discomfort and irritation, particularly in the throat if ingested.

Other symptoms such as abdominal pain, nausea, or vomiting may also arise, but they are secondary to the more distinctive sensation in the throat, which is a hallmark of Anisakis infection. Understanding the typical presentation of Anisakis infection is crucial for proper diagnosis and treatment, emphasizing the importance of thorough food safety practices when handling seafood.
