Anisakis simplex

Anisakis simplex is the most common hidden allergen in food and should be considered as a possible causative food allergen in adult patients presenting with urticaria, angioedema, and anaphylaxis followed by abdominal pain, nausea, vomiting, and diarrhea get infected by the consumption of raw fish or seafood. , anisakiasis (using the term in the broad sense) is caused mainly by the accidental ingestion of larvae of the nematodes (roundworms). Anasakiasis occurs worldwide, with a higher incidence in regions where raw fish is commonly eaten.Anisakis simplex is the most common helminth infection in humans resulting from the consumption of raw or undercooked fish

Food Source
raw or undercooked seafood: marine fish and cephalopods.cows' milk, eggs, peanuts, wheat, soy, tree nuts, fish, and shellfish
Pathological Factor
Anisakiasis is caused by the accidental ingestion of larvae of the nematodes (roundworms) Anisakis simplex and Pseudoterranova decipiens.Anisakidae larvae can cause anisakiasis when ingested by humans.Most commonly can be parasitized by third-stage Anisakis larvae. Anisakis was confirmed by detecting serum specific IgE to Anisakis simplex. Infestation with A. simplex causes direct tissue damage following an invasion of the gut wall, the development of an eosinophilic granuloma, the perforation of the gut, and strong allergic reactions.
Disease
A . simplex extracts are now in- cluded in the standard sets of allergens for the investigation of food allergies.Infective-stage larvae found within the flesh of sea fish or cephalopods can be ingested alive by humans, causing ani- sakidosis and also associated with hypersensitivity cases and most commonly with urticaria. Anisakis was confirmed by detecting serum specific IgE to Anisakis simplex.The most common manifestation of anisakiasis was urticaria (100%), followed by abdominal pain (30%) and anaphylaxis .
