[Method] In 2008, catfish and catfish were collected from Huidong County and Huiyang City under the jurisdiction of Huizhou Prefecture, and the metacercaria of Clonorchis sinensis was examined by artificial digestion method. [Results] The positive rate of Cytotoxicity of Clonorchis sinensis was 11.85%, and the average infection rate of positive Cyaroid larvae was 15.76 / tail. The positive rate of Clonorchis sinensis metacercaria was 1.67 %, The average positive infection of metacercariae is 1.60 / tail.
