Abstract
Intestinal anisakiasis is a disease caused by human infection by Anisakis larva that can be found in undercooked fish that is increasing worldwide. The symptoms, typically abdominal pain, develop within 5–7 days after the fish intake. The diagnosis may be suspected based on common anamnesis (unfrozen fish intake) with abdominal pain or bowel obstruction and confirmed by blood serology. Resective surgery is only used in severe cases.
