Anisakiasis is caused by a fish parasite of the Nematode family. This kind of rare helminthozoonosis can mainly be found in countries where consumption of raw fish is traditionally high like Japan, the Netherlands, Pacific Islands, South Europe, Scandinavia, USA, and Canada. Man is the wrong hoste. Clinical manifestation depends on the localisation of penetration in the GI tract. In Japan, predominantly the stomach is affected in 97 % of cases, probably due to hypo- and achlorhydria; whereas mainly intestinal anisakiasis occurs in Europa. We report on a 67-year-old male patient with a gastric infestation of anisakiasis. The patient was on proton pump inhibitor which migh have caused the localisation of the infestation. The anisakis was an accidental endoscopic finding in a patient for control of an H. p.-positive gastric ulcer. Otherwise the patient was free of pain. The helminth (larva III) was endoscopically extracted. Thereafter, the patient remained in good health. Anisakis serology as well as repeated differential blood counts were without finding. The uneventful medical history and the normal blood findings indicate that our patient had a very early stage of infestation of anisakiasis. The patient reported no stay outside of Austria within the last years. However, he consumed on a regular basis "rolled pickled herring" produced by a well-known Viennese company for canned fish. This is the first documented case of this rare helminthozoonosis acquired in Austria.
