Abstract: Objective To analyze the infection status and the awareness of preventing knowledge of food-borne parasitic diseases in Shenzhen and provide prevention and control strategies for food-borne parasitic diseases. Methods Specific antibodies of Clonorchissinensis, Hydatid, Paragonimus, Trichinellaspiralis, Cysticercus, Sparganum and Angiostrongyluscantonensis were detected by ELISA and characteristics of parasite infection were analyzed using descriptive epidemiological method. Meanwhile, the questionnaire about preventing food-borne parasitic diseases was carried out in outpatients. Results The total serum antibody positive rate of food-borne parasitic diseases was about 28.14% in 757 outpatients. The serum antibody positive rates of Clonorchissinensis, Hydatid, Paragonimus, Trichinellaspiralis, Cysticercus, Sparganum and Angiostrongyluscantonensis were 11.40%, 4.78%, 1.06%, 0.67%, 8.72%, 4.62%, and 4.62% respectively. The infection rate of males was higher than that of the females. The 21-50 years old group have the highest infection rate. There were no significant differences between gender and age as for infection rate（P>0.05）. The awareness rate about preventing food-borne parasitic diseases was 69.15% in outpatient. 60.73% of outpatients knew the ways of food-borne parasitic infection. Conclusion The serum antibody positive rates of Clonorchissinensis are relatively high in Shenzhen and the distribution of food-borne parasitic diseases show gender and age related features. In addition, the food-borne parasitic diseases are the major parasitic disease to be prevented in Shenzhen areas and the healthy diet habit should be widely educated.
