Using data from 2018-2019 health insurance claims, we estimated the average annual incidence of anisakiasis in Japan to be 19,737 cases. Molecular identification of larvae revealed that most (88.4%) patients were infected with the species Anisakis simplex sensu stricto. Further insights into the pathogenesis of various anisakiasis forms are needed.

Review
Anisakidosis is a zoonotic parasitosis induced by members of the family Anisakidae. The anisakid genera includes and . The final definitive hosts of these nematodes are marine mammals with a complex life cycle. These nematode parasites use different crustaceans and fish species as intermediate or paratenic hosts and humans are accidental hosts. Human anisakiasis, the infections caused by members of the genus occurs when seafoods, particularly fish, contaminated with the infective stage (third stage larvae [L3]) of this parasite, are consumed. Pseudoterranovosis, on the other hand is induced by members of the genus These two genera of anisakids have been implicated in human disease globally. There is a rise in reports of gastro-intestinal infections accompanied by allergic reactions caused by and . This review provides an update on current knowledge on as a food-borne parasite with special focus on the increasingly reported diversity of fish and crustacean hosts, allergens and immunological cross-reactivity with invertebrate proteins rendering this parasite a significant public health issue.

Anisakis is a parasite with life cycles involving fish and marine mammals. Human infection, anisakiasis, occurs with the ingestion of raw infected seafood and usually presents with acute or chronic gastrointestinal symptoms from esophageal or gastric invasion. We report a rare caseinvolving the oral cavity. A 39-year-old male presented with oral and sub-sternal pain of one day duration after eating raw cuttlefish. Physical examination revealed areas of erythema and edema with a central white foreign particle on the labial and buccal mucosa. With microscopic field we could remove the foreign material from the lesions. The foreign material was confirmed to be Anisakis. Anisakis was also removed from the esophagus by esophagogastroduodenoscopy. The patient was discharged the following day without complication. Anisakiasis is frequently reported in Korea and Japan, countries where raw seafood ingestion is popular. The symptoms of acute anisakiasis include pain, nausea, and vomiting and usually begin 2-12 hours after ingestion. The differential diagnosis includes food poisoning, acute gastritis, and acute pancreatitis. A history of raw seafood ingestion is important to the diagnosis of anisakiasis. Treatment is complete removal of the Anisakis to relieve acute symptoms and prevent chronic granulomatous inflammation.

BACKGROUND
To assess the frequency of appearance of various signs (isolated and grouped) in emergency imaging tests in patients with anisakiasis, according to the location of gastrointestinal tract involvement.
METHODS
Retrospective review by two experienced radiologists of emergency ultrasounds and CTs performed on patients admitted in the Emergency Department of our hospital with later confirmed anisakiasis (2010-2021), assessing the presence of signs suggesting anisakiasis. Calculation of the frequency of appearance according to the gastric or intestinal location, as well as the most common grouped signs.
RESULTS
Out of 231 total patients with anisakiasis, imaging studies were performed in 144: abdominopelvic ultrasound in 43 cases and CT in 111 (both techniques in 31). In cases with gastric occurrence (34), in CT the wall stratification (100%), wall thickening (97%), fat stranding (91%) and ascitic fluid (82%) were predominant. In the intestinal cases (105), in CT (95) the wall thickening (100%), fat stranding (92%) and mesenteric vessel engorgement (83%) were usual; in ultrasound (40), ascitic fluid and wall thickening (70% in both cases) were frequently observed. The frequency of grouped appearance of the mentioned signs was 82% in gastric cases, 80% in intestinal cases and 50% in ultrasounds. Multisegment involvement in CT reached 28% (gastric + intestinal) and 11% (only intestinal) of cases.
CONCLUSIONS
The most frequent CT findings in patients with gastric anisakiasis are wall stratification and thickening, fat stranding and ascitic fluid. In the intestinal cases, wall thickening, fat oedema and vessel engorgement are the most often observed findings.
CRITICAL RELEVANCE STATEMENT
The presence of different radiological signs makes it advisable to include anisakiasis in the differential diagnosis of acute abdomen. Intestinal and multifocal involvement rates are greater than previously reported.
KEY POINTS
• In gastric anisakiasis, CT frequently shows wall stratification and thickening, fat stranding and ascitic fluid. • In intestinal anisakiasis, CT often presents wall thickening, fat stranding and vessel engorgement. • In intestinal anisakiasis, ultrasounds most frequently show ascitic fluid and wall thickening.

Review
Nematodes of the Anisakidae family have the ability to infest a wide variety of aquatic hosts during the development of their larval stages, mainly marine mammals, aquatic birds, such as pelicans, and freshwater fish, such crucian carp, these being the hosts where the life cycle is completed. The participation of intermediate hosts such as cephalopods, shrimp, crustaceans and marine fish, is an important part of this cycle. Due to morphological changes and updates to the genetic information of the different members of the family, the purpose of this review was to carry out a bibliographic search of the genus and species of the Anisakidae family identified by molecular tests, as well as the geographical area in which they were collected. The Anisakidae family is made up of eight different parasitic genera and 46 different species. Those of clinical importance to human health are highlighted: , . , , , . , . and . . The geographical distribution of these genera and species is located mainly in the European continent, Asia and South America, as well as in North and Central America and Australia. Based on the information collected from the Anisakidae family, it was determined that the geographical distribution is affected by different environmental factors, the host and the ability of the parasite itself to adapt. Its ability to adapt to the human organism has led to it being considered as a zoonotic agent. The disease in humans manifests nonspecifically, however the consumption of raw or semi-raw seafood is crucial information to link the presentation of the parasite with the disease. The use of morphological and molecular tests is of utmost importance for the correct diagnosis of the genus and species of the Anisakidae family.

Review
Anisakiasis is an arising zoonosis induced by parasitic nematodes belonging to the family Anisakidae. Anisakiasis is often caused by the ingestion of larval nematodes in uncooked or minimally processed seafood dishes, which are regularly consumed by humans. Significant potential sources of infection are raw fish (e.g., sushi and sashimi) that can be found in traditional Japanese cuisine and can be part of the culinary tradition of consumption of raw or marinated fish that is particularly diffused in European countries. During the last five decades, the global prevalence of human anisakiasis has been rising, becoming an emergent major public health problem. Thus, there is an unmet need for well-defined and cost-effective methods aimed at killing Anisakis larvae, thus reducing the incidence of anisakiasis. In this mini-review, we discuss the clinical features of anisakiasis as well as the effectiveness and mechanisms of action of the main methods employed for increasing seafood safety and killing Anisakis larvae, including freezing, heating, use of high hydrostatic pressure, salting process, pepsin digestion method and use of garlic oil.

Review
Anisakiasis is a zoonotic parasitic disease caused by consumption of raw or undercooked fish or seafood infected with nematodes of the Anisakis, Pseudoterranova or Contracaecum genera. Here, we describe the first case of anisakiasis in Colombia and summarize the available literature. A 52-year-old female with a history of abrupt-onset sharp epigastric pain, nausea, vomit, diarrhea, and urticaria following fish consumption consulted the health service. The physical examination revealed moderate tenderness of the epigastric region; the laboratory evaluation showed leukocytosis and a simple X-ray and ECG showed no abnormalities. The diagnosis was made by endoscopic examination, which revealed a thickened gastric wall and a moving larval worm. An Anisakis larva was found and extracted endoscopically, which relieved the pain of the patient. Clinically, anisakiasis may present as a gastric, intestinal, extragastrointestinal or allergic disease. Diagnosis and treatment of anisakiasis are made by a dietary history, direct visualization and endoscopic extraction of possible larvae, which is the only effective therapy.
