Abstract: Objective To understand the parasitic infection status marketed freshwater products in Fujian province for evidences to develop scientific prevention and control strategies for the foodborne infection. Methods By the Monitoring Program for Food Contamination and Hazardous factors in Fujian province issued by Fujian provincial Health Commission,we conducted an investigation on the freshwater fish and snails sold in the supermarkets or farmer’s markets in the East,South, West,North and Central Fujian areas using stratified random sampling method. The samples were obtained and undergone detection of the larvae and metacercariae of the parasites via digestion technique,slide glass and autopsies. Results Totally,2 232 freshwater fish belonging to 26 species were collected from 2014 to 2019. The detection rate was 0. 09%(2 / 2 232) for Clonorchis sinensis ,3. 76% ( 84 / 2 232) for the larvae of Gnathostoma ,and 0. 17% ( 2 / 1 190) for the larvae of Angiostrongylus cantonensis in loach. No parasites were detected in the 90 samples of Cipangopaludina chinensis and 120 aliquots of Bellamya aeruginosa. Conclusion Food-borne parasitic infection exists to a certain degree in the fresh aquatic products sold in Fujiang areas,which suggests that intake of raw or under-cooked freshwater products can be great risks with parasitic infection. Therefore,health education should be strengthened and effective measures should be taken in order to ensure food safety in population.
