Prevalence of Parasitism by Anisakis in a Sample of Fish Caught in Coastline of the Golfete of Coro, Venezuela

Abstract

To evaluate the risk of Anisakiasis in the population, a common zoonotic disease worldwide caused by ingestion of larvae (L3) of the nematode family anisakidae (Anisakis spp, Contracaecum spp, Pseudoterranova spp) present in raw fish or undercooked constitute a health risk that should not be underestimated; fish caught in the area Golfete of Coro, Venezuela Falcon state. Artisanal trawling shore and depth serve as financial support to numerous fishing villages located along the western coast of the isthmus of dunes, the Peninsula Paraguana where trade in species of different orders of zoological scale marine fauna existing there. A study was conducted to determine the degree of parasitism by anisakidae family, using a non-probability purposive sampling 90 specimens were purchased directly from fishermen, giving prevalence to the lowest economic value, which also are used for family consumption as: mullet (Mugil Mugil curema or incilis), mullet (Mugil liza), crappie (Eugerres plumieri) and catfish (Ictalurus punctatus) among others. They moved to the laboratory for: evisceration, debridement and muscle dissection seeking parasites. Nematodes of the family anisakidae identified in the sample were Contracaecum spp. 97% and pseudoterranova spp. 3%, and those with high degree of infestation were 88.8% and mojarra smooth 80% with parasite loads ranging from seven to nine parasites per specimen, demonstrating a high parasitism.
