What are the risks of eating uncooked fish when traveling to South East Asia (Thailand, Vietnam, Malaysia)? How can one avoid them?

As travelers embark on their journeys to South East Asia, the region’s rich cultural heritage, breathtaking landscapes, and mouthwatering cuisine beckon. Among the gastronomic delights, seafood holds a special place, with its vibrant flavors and diverse preparations.


However, it is crucial for visitors to be aware of the potential risks associated with consuming uncooked fish in countries such as Thailand, Vietnam, and Malaysia. In this article, we delve into these risks and provide essential tips to ensure a safe culinary experience.

While raw or undercooked fish dishes, like sushi or ceviche, have gained popularity worldwide, certain precautions are necessary when indulging in these delicacies in South East Asia. The primary concern lies in the presence of parasites, such as tapeworms and roundworms, which can infect the human digestive system and cause health issues.

Fish that is not cooked to an adequate temperature may contain these parasites, posing a risk to travelers who consume it. The risk is particularly significant in countries like Thailand, Vietnam, and Malaysia, where raw fish dishes are prevalent in local cuisine. Uncooked fish can be found in dishes like Thai fish salad (Yam Pla Dook Foo), Vietnamese raw fish salad (Goi Ca), or Malaysian-style sashimi (Ikan Mentah).


To avoid the potential health hazards associated with uncooked fish, travelers are advised to follow these essential precautions:

  1. Choose reliable and reputable establishments: Opt for restaurants, food stalls, or markets that are well-established and have a good reputation among locals and fellow travelers. These establishments are more likely to prioritize food safety and adhere to proper hygiene standards.
  2. Ensure proper handling and storage: When purchasing fish or seafood, observe how it is handled and stored. Fresh fish should be kept at appropriate temperatures, and vendors should use gloves and clean utensils to prevent cross-contamination.
  3. Select thoroughly cooked fish: When ordering fish dishes, opt for options that are fully cooked. Grilled, baked, or steamed fish are generally safe choices, as they are cooked at high temperatures, reducing the risk of parasites and other contaminants.
  4. Be cautious with raw fish dishes: If you still desire to try raw fish dishes, exercise caution. Choose reputable restaurants or specialized sushi bars that adhere to strict hygiene standards. Ask about the fish’s source and inquire about the establishment’s handling practices to ensure maximum safety.
  5. Be aware of local customs: Familiarize yourself with local customs and practices regarding seafood consumption. Some dishes might be prepared in a way that minimizes the risk of parasites or uses specific ingredients to counteract them. Locals can provide valuable insights into safe culinary experiences.
  6. Stay informed and up-to-date: Keep yourself informed about any local advisories or warnings related to seafood consumption. Stay updated with travel advisories issued by your country’s embassy or consulate to ensure you have the latest information regarding food safety in your destination.

By following these guidelines, travelers can savor the delightful flavors of South East Asia’s seafood while minimizing the risks associated with consuming uncooked fish. Remember, it’s always better to prioritize your health and well-being, even in the pursuit of culinary adventures.

Travelers should consult their healthcare providers or travel clinics before their trip for personalized advice based on their health conditions and individual circumstances.
