Opisthorchiasis - Prevention

Prevention

Currently, there is no effective chemotherapy to combat cholangiocarcinoma, such that intervention strategies need to rely on the prevention or treatment of liver fluke infection/disease. Although effective prevention could be readily achieved by persuading people to consume cooked fish (via education programs), the ancient cultural custom to consume raw, undercooked or freshly pickled fish persists in endemic areas. Cooking or deep-freezing (-20 °C for 7 days) of food made of fish is sure method of prevention. Methods for prevention of Opisthorchis viverrini in aquaculture fish ponds were proposed by Khamboonruang et al. (1997).
