| Abstract |
| Background and aim: Fishborne zoonotic trematode (FZT) diseases are transmitted to humans and animals by eating raw/undercook fish. FZT are of particular importance in Asia. The aim of the present study is to determine the risk of FZT infections by eating raw fish of Vietnam’s Thai people. Materials and methods: The survey were conducted from June to July 2024 in Muong La and Son La city, Son La Province. Restaurants that serve raw fish salad were selected for the survey. Brief interviews were conducted with restaurant staffs and customers. Raw fish salad sample were collected at the restaurant. Fish were collected from fish pond that supplies fish to restaurant. Fish samples were transferred to the lab for examination. Snail were collected and examined by cutting and crushing method. Metacercariae species and cercariae group were morphological identified. Results: The results showed that Vietnam’s Thai people love to eat raw fish salad. Two raw fish dishes were prepared: raw fish salad made from grass carp, local name “Gỏi cá”; and jumping fish salad made from juvenile common carp, local name “Cá nhảy”. Vietnam’s Thai people have been eating raw fish for many generations and they think eating raw fish makes the body healthy. Small liver fluke was not found in fish sample but two smaill intestinal fluke metacercaria species were found. One Haplorchis pumilio metacercaria was found in grass fish salad. Metacercaria of Centrocestus formosanus were found in common carp with infection rate 13.6% (27/198). Melanoides tuberculatus is 1st intermatidate host of small intestinal fluke in study area, pleulophocercous cercaria infection rate was 9.17% (30/327). Conclusion: The risk of people being infected with FZT is very high. The results of this study contribute to raising awareness about the prevention of FZT infection to improve public health and one health approach. |
