“…However, rDNA or mtDNA gene sequencing made this identification clear (100% identity in ITS region and 97.1–98.1% identity in cox2 ). Anisakis type I has been known to be the main larval type in the sea eel in Korea; however, A. pegreffii had been rarely documented in earlier studies [18]. According to a recent study, Cho et al [18] clarified that the major species of anisakid larvae in the sea eel in Korea was A. pegreffii to which our results fully agree.…”

Anisakiasis is a zoonotic disease induced by anisakid nematodes, and endoscopic inspection is used for a diagnosis or remedy for it. Anisakis simplex, Anisakis physeteris , and Pseudoterranova decipiens had been reported to be the major species causing human infections, particularly, in Japan. However, in Korea, recent studies strongly suggested that Anisakis pegreffii is the major species of human infections. To support this suggestion, we collected anisakid larvae (n=20) from 20 human patients who were undergone gastrointestinal endoscopy at a health check-up center in Korea, and molecular identification was performed on the larvae using PCR-RFLP analysis and gene sequencing of rDNA ITS regions and mtDNA cox2 . In addition, anisakid larvae (n=53) collected from the sea eel ( Astroconger myriaster ) were also examined for comparison with those extracted from humans. The results showed that all human samples (100%) were identified as A. pegreffii , whereas 90.7% of the samples from the sea eel were A. pegreffii with the remaining 9.3% being Hysterothylacium aduncum . Our study confirmed that A. pegreffii is the predominant species causing human anisakiasis in Korea, and this seems to be due to the predominance of this larval type in the fish (sea eels) popularly consumed by the Korean people. The possibility of human infection with H. aduncum in Korea is also suggested.

“…Among them, A. simplex sensu stricto was found distributed in the North and on the Pacific coast, and A. pegreffii was discovered in the South on the coast of the Sea of Japan. In the waters near South Korea, the infection rate of A. pegreffii in sea eels is 86.8%, while the infection rate of typical Anisakis is 7.8%, and 5.4% are unspecified, indicating that A. pegreffii has a selective advantage in the waters near South Korea (Table 1) [25][26][27][28][29][30]. Note: Infection rate (%)=Number of infected fish / total number of checked fish x 100.…”

Effects of Anisakis Allergenic Proteins on Fish-Borne Food Safety Risks

Anisakis (mainly Anisakis spp.) is a global public health and socio-economic concern. The infective third stage larva (L3) of these nematodes, which may be present in the muscle of fish and squid, is the etiological agent of an underestimated, emerging fish-borne zoonotic disease called anisakiasis (or anisakidosis). With the globalization of the seafood industry and the diversification of eating habits, anisakiasis is distributed worldwide, which seriously threatens human health. However, the risk of humans acquiring anisakiasis in developed countries with the habit of raw fish consumption appears to be underestimated.Current knowledge of Anisakis as a food-borne parasite with special focus on Anisakis larvae infection in marine fish, life cycle, geographical distribution, epidemiology, allergenic protein residue of A. simplex, are critically reviewed. Research on residues from allergenic proteins of Anisakis remained in processed fish products and their health risks to susceptible consumers are discussed for prevention and control of this parasite.Anisakis is ubiquitous in the world's oceans, but there are differences in the number and species of this nematode with geographical location. Conventional thermal processing like freezing, heating, smoke curing and non-thermal processing such as salting and pressure have shown potential effects on elimination or reduction of food allergenic proteins, however, similar effects on residual Anisakis allergenicity are unknown. Potential harm or risk of these parasitic allergenic proteins to consumers is scarce in the published literature. Further research on assessment and technical control of Anisakis allergenic proteins in fish-borne food is proposed for fish food safety in aquatic industry.

“…Humans acquire the infection by eating raw or undercooked infected marine fish, squid, clams, or eels. [3][4][5] After ingestion of the L3 larvae, humans can exhibit gastric, intestinal, extraintestinal, or allergic symptoms. 3,4,[6][7][8] Patients may present with epigastric pain, nausea, vomiting, symptoms of bowel obstruction, acute abdomen, or symptoms of allergic reaction such as urticaria, and angioedema.…”

Abstract. Human anisakiasis is a zoonosis acquired by eating raw or undercooked infected seafood. Herein, we report a case of acute dysentery caused by anisakiasis in a 64-year-old man in Malaysia. A colonoscopy was performed and a nematode larva was found penetrating the mucosa of the ascending colon. Bleeding was observed at the site of penetration. Y-shaped lateral epidermal cords were seen from the cross section of the worm, which is a prominent feature of Anisakis larva. Molecular analysis using polymerase chain reaction of cytochrome oxidase 2 (cox2) gene confirmed the specimen to be larva of Anisakis simplex.
