Thailand Health Officials Warn Over Liver Flukes Linked to Raw Fish and Bile Duct Cancer
Thai health officials have issued a warning regarding liver flukes (Opisthorchis viverrini) found in raw fish, highlighting their link to an increased risk of bile duct cancer. The concern is particularly high in the North and Northeast, where traditional raw fish consumption is prevalent. A health advisory through July 2026 emphasizes the importance of thorough cooking.
Thailand's health authorities have extended a warning regarding liver flukes (Opisthorchis viverrini), particularly linked to the consumption of raw fish, through July 2026. The parasite spreads when people consume infected freshwater fish that have not been thoroughly cooked. The risk is notably elevated in the northern and northeastern regions of Thailand, where eating raw fish is a deeply ingrained part of traditional culinary practices. Chronic infection with liver flukes can lead to persistent inflammation in the liver, significantly increasing the risk of developing bile duct cancer over time, according to medical findings. Health officials are strongly advising the public to ensure all fish and seafood are cooked thoroughly to the core to prevent foodborne illnesses and protect public health. This ongoing advisory highlights the intersection of traditional food habits and public health challenges in Thailand. Source: Chiang Rai Times
