The popularity of such raw fish dishes makes it important for consumers to be aware of this risk. Raw fish should be frozen to an internal temperature of −20 °C (−4 °F) for at least seven days to kill parasites. It is important to be aware that home freezers may not be cold enough to kill parasites. [67] [68]
The genus Anisakis was defined in 1845 [2] by Félix Dujardin as a subgenus of the genus Ascaris Linnaeus, 1758.Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("mâles ayant des spicules inégaux"); thus, the name Anisakis is based on anis-(Greek prefix for different) and akis (Greek for spine or spicule).
Trematodes can cause disease in many types of vertebrates, including mammals, birds, reptiles, and fish. Cattle and sheep can become infected by eating contaminated food. These infections lead to a reduction in milk or meat production, which can be of significant economic importance to the livestock industry.

In fish, the disease is most important in salmonids. Marine and freshwater fish can be infected. These protozoans can be found on most continents. Bloodfeeding leeches are implicated in the transmission of the bloodborne species. The protozoans can be identified in skin and gill biopsies and blood samples.
The economic impact of such parasites can be severe, especially where prevalence rates are high; they may also have a severe impact on wild fish stocks. The diseases caused by myxosporeas in cultured fish with the most significant economic impact worldwide are proliferative kidney disease (PKD) caused by the malacosporean T. bryosalmonae, and ...
These digeneans are themselves parasites in various vertebrates and molluscs. Eight of these species belong to the genus Nosema. [25] Similarly, the microsporidian species Toguebayea baccigeri is a parasite of a digenean, the faustulid Bacciger israelensis, itself an intestinal parasite of a marine fish, the bogue Boops boops (Teleostei ...
