Predictive risk factors towards liver fluke infection among the people in Kamalasai District, Kalasin Province, Thailand.
SAGE open medicine, 2019Co-Authors: Woragon Wichaiyo, Wirat Parnsila, Wisit Chaveepojnkamjorn, Banchob SripaAbstract:Background Liver fluke disease caused by Opisthorchis viverrini remains a major public health problem with its crucial risk factors caused by some individual habits or false beliefs among the people in northeastern Thailand concerning the consumption of Raw Fish meat dishes. Objectives This study explores the predictive risk factors for the infection of liver fluke disease. Methods The sample consisted of 400 people aged 30 years and above in Thanya sub-district, Kamalasai district, Kalasin province. A cross-sectional analytic study, using the χ2 test, odds ratio and 95% confidence interval, was used to find the influence of each variable, along with the use of multiple logistic regression (p = 0.05). A questionnaire form was used as the research instrument. Results Factors found in the results are as follows: households with a cat were 7.00 times more at risk than households without a cat; eating Raw Fish dishes prepared by themselves increases the risk of infection by 2.58 times; eating Raw Fish dishes prepared by family members increases the risk by 4.74 times; and Raw Fish dishes bought from a community market increases the risk by 2.33 times. Conclusion A campaign should be launched to educate people not to eat Raw or undercooked Fish dishes, but to fully cook Fish dishes before eating, as the food is still delicious, but also safe, healthy, and free from liver fluke infection.

Social Influence in Liver Fluke Transmission: Application of Social Network Analysis of Food Sharing in Thai Isaan Culture
Advances in parasitology, 2018Co-Authors: Waraphon Phimpraphai, Sirikachorn Tangkawattana, Suwicha Kasemsuwan, Banchob SripaAbstract:In northeastern Thai (Isaan) culture traditional Raw Fish dishes and Raw Fish-eating habits are common. Eating and sharing meals together among the community's members, especially relatives and neighbours, are a common practice in both daily life and social gathering events. Fish are a significant protein source and are associated with variety of traditional recipes. Cyprinid Fish are one of the most preferred Fish by Isaan villagers for daily consumption because they are accessible and affordable. Consumption of these Fish probably causes the persistence of high endemicity of human liver fluke infection, particularly with Opisthorchis viverrini, in northeast Thailand. Because the consumption of Raw cyprinid Fish is a well-documented risk factor for liver fluke infection, sharing of risky Raw Fish dishes may influence disease transmission through a community. Social network analysis was used to investigate Fish and Fish-based meal sharing among household members in Isaan villages in liver fluke endemic areas. The findings from three studies confirmed the persistence of traditional Isaan Raw Fish consumption and food-sharing practice. Social connections via food sharing among villagers played an important role in liver fluke infection and transmission dynamics as a risk factor. Thus these sociocultural factors should be taken into account in designing strategies for control of opisthorchiasis and other food-borne illnesses at the community level.

risk factors for clonorchis sinensis infection transmission in humans in northern vietnam a descriptive and social network analysis study
Parasitology International, 2017Co-Authors: Hoang Quang Vinh, Waraphon Phimpraphai, Sirikachorn Tangkawattana, John F Smith, Sasithorn Kaewkes, Do Trung Dung, Tran Thanh Duong, Banchob SripaAbstract:Clonorchis sinensis is major Fish-borne trematode, endemic in North Vietnam. Risk factors described so far include individual eating behaviors and environmental factors. Here, additional to conventional risk factors, we report on socially influenced liver fluke transmission in endemic communities. A cross-sectional study on risk factors and Fish sharing networks was conducted in 4 villages of Gia Thinh Commune, Ninh Binh Province. A total of 510 residents in 272 households were recruited for risk factor analysis while 220 households, 28 Fishermen and 10 Fish-sellers were enrolled for social network study. Fecal examination for C. sinensis eggs was performed. Average C. sinensis infection rate at Gia Thinh commune was 16.5% (range 2% to 34.4%). Higher infection rates were significantly associated with males, lower educational levels, eating Raw Fish, and location of the villages. Social network analysis (SNA) showed a strong positive correlation between ego network size (number of households in Fish sharing network) and quantity of Raw Fish consumed (r=0.603, P<0.05). The infection rate in people who ate Raw-Fish caught from a nearby river was significantly higher than those who consumed Fish taken from farmed ponds (P<0.05). The amount of Raw-Fish meal consumed per resident/year was significantly higher in villages that had a strong network of sharing Raw-Fish food (P<0.001). This study reports for the first time on Fish-food sharing among neighbors, proximity to water bodies, frequency of eating Raw Fish from natural water bodies and low education were key risk factors in C. sinensis infection transmission in northern Vietnam.

Fish sharing as a risk factor for Opisthorchis viverrini infection: evidence from two villages in north-eastern Thailand
BMC, 2017Co-Authors: Parichat Saenna, Cameron Hurst, Pierre Echaubard, Bruce A. Wilcox, Banchob SripaAbstract:Abstract Background Foodborne trematodiasis (FBT) is a significant global health problem, with the liver flukes Opisthorchis viverrini, O. felineus, and Clonorchis sinensis contributing to half of the global burden of FBT. North-eastern Thailand where O. viverrini is endemic and un-cooked Fish dishes remain an integral part of the food culture has the highest reported incidence of opisthorchiasis, including associated cholangiocarcinoma. Both food sharing and eating practices are potentially important factors in FTB, suggesting an important role for the social ecology of disease transmission in these rural communities. Methods Two rural Thai-Lao villages that were part of a 12-village project in Northeastern Thailand were selected for detailed investigation of O. viverrini infection risk associated with sharing of Raw Fish dishes among households. The project included screening individuals for infection and cholangiocarcinoma, a household questionnaire, and offering treatment options for positive individuals. Social network mapping was used to construct Raw Fish dish-sharing networks and create a proxy variable capturing variability in the degree of food sharing (DFS), measured as the number of different households with which each household shared Fish dishes. Measures of associations between DFS, O. viverrini infection, the frequency of Raw Fish consumption, and the number of Raw Fish dishes consumed were generated using binary logistic regression, proportional odds ordinal logistic regression, and Poisson regression. Results The results showed that the probability that a household has members infected with O. viverrini increased by ~7% (P

Raw Fish eating behavior and Fishborne zoonotic trematode infection in people of northern vietnam
Foodborne Pathogens and Disease, 2011Co-Authors: Van Thi Phan, Annette Kjaer Ersboll, Anders DalsgaardAbstract:Abstract Raw Fish consumption in restaurants, for example, Sashimi style, is popular worldwide. In Vietnam, Raw Fish dishes are also traditionally prepared and consumed in private households. However, the habits of eating Raw or otherwise inadequately cooked Fish can be associated with risks of acquiring Fishborne zoonotic trematode (FZT) infection. The present study was done in a Fish-farming community in Nam Dinh, Vietnam, to obtain information about habits of eating Raw Fish dishes and risks for human FZT infection. Discussions were held in different groups divided by gender and age on Raw-Fish-eating behavior. A total of 180 household members were interviewed and their stool samples analyzed to identify risk factors of FZT infection. There was awareness about the risk of liver fluke infections from eating Raw Fish. However, many older people accepted these risks and continued eating Raw Fish, as they know effective drug treatment is available. Raw Fish dishes are consumed at social gatherings from sha...

Fishborne zoonotic trematodes in Raw Fish dishes served in restaurants in Nam Dinh Province and Hanoi, Vietnam.
Journal of food protection, 2009Co-Authors: Tran Thi Kim Chi, K. Darwin Murrell, Henry Madsen, Nguyen Viet Khue, Anders DalsgaardAbstract:Fishborne zoonotic trematode (FZT) parasites are a serious food safety problem in Asian countries because of their tradition of eating Raw Fish. In northern Vietnam, the prevalence of FZT metacercariae (MC) in wild-caught and cultured Fish is quite high. The objective of this study was to assess the risk for acquiring these parasites from Raw Fish dishes prepared in restaurants. Samples of Fish meat (body muscle) and remainder parts (head, gills, fins, skin, and muscle tissue from the tail) were obtained from 39 restaurants located in Nam Dinh province, an area endemic for FZTs, and from 74 restaurants in the capital city of Hanoi. Six species of zoonotic intestinal trematodes were recovered from a total of nine freshwater and brackish water Fish species. Overall, the prevalence of MC in meat samples was 6.1% and in remainder samples, 34.9%; freshwater Fish were more often infected (39.4%) than brackish water species (16.0%). Dishes from Nam Dinh restaurants were more often infected (11.8%) than those fro...

Antimutagenicity of Tochu tea (an aqueous extract of Eucommia ulmoides leaves): 2. Suppressing effect of Tochu tea on the urine mutagenicity after ingestion of Raw Fish and cooked beef.
Mutation research, 1996Co-Authors: Yūf. Sasaki, Aki Chiba, Michiko Murakami, Kaoru Sekihashi, Makiko Tanaka, Mikako Takahoko, Sayuri Moribayashi, Chihiro Kudou, Yasuko Hara, Yoshihisa NakazawaAbstract:Abstract The effect of Tochu tea, which is an aqueous extract of Eucommia ulmoides leaves and a popular beverage in Japan, on the urine mutagenicity before and after ingestion of Raw Fish and cooked beef was studied using Salmonella typhimurium YG1024. Urines were collected from seven healthy, non-smoking Japanese women before and after ingestion of Raw Fish and cooked beef. In experiment 1, 3 were in a control group and 4 were in a Tochu tea-drinking group (2000 ml per day). The mutagenicity of urine from the Tochu tea-drinking group was much lower. In experiment 2 the 7 women switched groups; the tea-drinking group became the control group, and the control group became the Tochu tea-drinking group. Again, the mutagenicity of urine collected from the Tochu tea-drinking group was much lower. These results suggest that the decrease in the mutagenicity of the urine from the Tochu tea-drinking group was due to the intake of Tochu tea, but not to individual differences. Thus, the ingestion of Tochu tea may reduce human exposure to dietary mutagens.
