Pseudoterranova Infections

Pseudoterranova is a genus of parasitic nematodes commonly found in marine mammals, especially seals and sea lions. Infections in humans occur when individuals consume raw or undercooked fish or squid contaminated with Pseudoterranova larvae. This condition, known as anisakiasis, primarily affects the gastrointestinal tract and can lead to symptoms such as abdominal pain, nausea, vomiting, and occasionally, allergic reactions. The larvae of Pseudoterranova attach to the mucosal lining of the stomach and intestines, causing localized inflammation and discomfort. In severe cases, complications such as intestinal obstruction or perforation may occur. Diagnosis involves a combination of clinical symptoms, endoscopic examination, and imaging studies. Prevention of Pseudoterranova infections includes proper cooking and freezing of fish and seafood, which kills the larvae and renders them noninfective. Additionally, increased awareness among consumers and chefs about the risks associated with consuming raw or undercooked seafood helps minimize the incidence of anisakiasis.
