Analysis on the risk factors of parasitic infections in fishery products

With the improvement of people's living standards,the domestic aquaculture grows fast and many fishery products import to the inland,the food safety problems caused by food-borne parasite are becoming increasingly serious,in addition to the problems caused by the heavy metal and pathogenic microorganism.Food and Agriculture Organization of the United Nations (FAO) made a list of 10 kinds of mermaid contract parasites,and regarded parasite as the top biohazard factor,especially the mermaid contract parasites.For example,the Diphyllobothrium and the Anisakis can parasite in the salmon,trout and tuna while the metacercaria Clonorchis sinensis can parasite in the freshwater fish,like the common grass carp and Pseudorasbora parva.So they may cause many parasitic diseases,and raise the new challenges for the sanitary authority.This article analyzed the hazard factors in the fishery products,like Anisakia,Gnathostoma,Diphyllobothrium,Clonorchis sinensis,and provide useful information for the studies in the safety of fishery products.
