Identification on the infection of Anisakis from marine fishes imported by Baiyun Airport

214 batches of marine fish imported in 2012-2015 from Baiyun Airport in Guangzhou were examined for Anisakis larvae by dissection and digest. 10 batches of Anisakis larvae were isolated from marine fishes by enzymatic degradation. Some Anisakis larvae isolated from imported marine fish were identified via morphology as the third larvae of Anisakis Type I and the rest were identified as the third larvae of Anisakis Type Ⅱ . Sequencing and phylogenetic analysis of the ribosomal internal transcribed spacer（ ITS） gene identified nematodes as A. simplex，A. physeteris and A. typica. The study has an important impact on the public health risk assessment，and also provides the reference for food safety risk assessment of imported marine fish and aquatic products.
