Tom yum kung and UNESCO: what the 2024 heritage file actually records
Tom yum kung joined UNESCO's intangible heritage list in December 2024. What the file says about who it belongs to, how it is passed on, and what Thailand must protect.
- UNESCO inscribed Tomyum Kung on the Representative List of intangible cultural heritage on 3 December 2024, at the 19th session in Paraguay.
- What was inscribed is a community's knowledge and practice, not one standard recipe. The file ties the dish to Buddhist riverside communities of the Central Plains.
- Thailand's safeguarding plan covers rivers, freshwater prawn farming, organic herbs and teaching in schools, not just promoting the dish.
Tom yum kung, the hot-and-sour prawn soup, was inscribed as intangible cultural heritage of humanity in December 2024. Many people read that as UNESCO declaring it the best soup in the world, or blessing one official recipe. It is neither. What was inscribed is the knowledge and way of life of the communities that make it. This article opens the file and looks at what it records, who it names as the dish’s keepers, and what Thailand promised to look after.
If you want the difference between clear and creamy tom yum, or how to order it, see Tom yum clear or creamy. This one is only about the inscription.
When and where
UNESCO’s Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage decided at its 19th session in Asunción, Paraguay, on 3 December 2024 local time, which was already 4 December in Thailand. Decision 19.COM 7.B.12 put “Tomyum Kung” (file no. 01879) on the Representative List.
The Representative List exists to show the diversity of the world’s living culture. It is different from the list for heritage in need of urgent safeguarding, which is for practices at risk of dying out. So tom yum kung is not listed as endangered. It is listed as an example of culture that is still very much alive.
Who the dish belongs to, according to the file
The file names the bearers clearly: Buddhist riverside communities of the Central Plains, farming and waterfront families, chefs, restaurant owners and community leaders.
The story it tells is worth knowing. The Central Plains are a fertile region and have long been the country’s main food-producing area. Buddhist communities there avoided killing large animals and turned instead to the freshwater prawns that were plentiful in the rivers. Their knowledge of medicinal herbs shaped the soup, which is believed to support energy and wellbeing, especially in the monsoon season. “Believed” is the file’s own word. It is not a medical finding.
How the file describes the dish
| Topic | What the file says |
|---|---|
| Core ingredients | Freshwater prawns, lemongrass, kaffir lime leaves, galangal, shallots, local condiments |
| Method | Prawns boiled with the herbs, then seasoned |
| Taste | Sweet, sour, salty, spicy, creamy and slightly bitter in one bowl |
| How it is passed on | By word of mouth in families and at gatherings; later through restaurants, organisations, schools and universities |
| What is passed on | Cooking, choosing herbs, and caring for the environment |
Notice what is missing. There are no quantities, no rule about chili paste or milk, and no split between clear and creamy. The file describes the core of the dish and puts its weight on the people and knowledge around it.
UNESCO inscribed the cooks’ knowledge, not a recipe. The tom yum your family makes is still yours to make your way.
What Thailand promised to look after
Every inscription comes with a safeguarding plan. The file sorts the measures into three groups.
- Past and current: reviving rivers, and research and documentation used in food campaigns at home and abroad.
- Proposed: environmental management programmes, research on freshwater prawn farming, and promotion of organic culinary herbs.
- Put forward by the communities themselves: protection from outside influences, promotion through television, curriculum development, capacity building, and food safety awareness.
The plan reaches well beyond the kitchen. If the rivers decline, the freshwater prawns go with them. If nobody grows lemongrass, galangal and makrut lime, knowing how to choose good herbs has nothing left to work on. The file ties the dish directly to its landscape.
Worked example: the 13-year road to UNESCO
The file gives enough dates to count the path step by step.
- 2011: tom yum kung enters Thailand’s National Inventory of Intangible Cultural Heritage, which must be updated at least every three years.
- 2019: a stakeholder consultation, followed by a focus group, an expert meeting and a public consultation that gave consent to the nomination.
- December 2024: UNESCO inscribes it.
From national list to world list: 2024 − 2011 = 13 years. If the inventory were updated exactly every three years, it would have been reviewed in 2014, 2017, 2020 and 2023, at least four rounds before inscription. From the first consultation to the decision: 2024 − 2019 = 5 years.
The committee also commended Thailand for a video showing broad community consent and participation. Community participation is one of the criteria a file must meet (criterion R.4). A government cannot simply nominate a dish on its own.
Where it sits among Thailand’s listings
UNESCO’s page for Thailand shows six elements on the Representative List.
| Year | Element |
|---|---|
| 2018 | Khon, masked dance drama |
| 2019 | Nuad Thai, traditional Thai massage |
| 2021 | Nora, dance drama of southern Thailand |
| 2023 | Songkran in Thailand |
| 2024 | Tomyum Kung |
| 2024 | Kebaya (shared with Brunei, Indonesia, Malaysia and Singapore) |
That makes tom yum kung Thailand’s first listing that is a dish. It came the same year as the kebaya, which Thailand’s Public Relations Department reported as a joint nomination of five countries.
Common mistakes
- Calling it “World Heritage”. World Heritage is for places. Tom yum kung is on the intangible cultural heritage list, under a different convention.
- Assuming there is now one official recipe. The file names the core ingredients and a broad method. It gives no quantities and does not rule out the creamy style.
- Saying tom yum cures illness. The file says it is believed to support energy and wellbeing. That is not a medical claim. If you are allergic to prawns or shellfish, tom yum kung is still a dish to avoid.
- Thinking inscription is the finish line. The safeguarding plan still has to be carried out. The rivers, prawns and herbs are part of the heritage too.
Summary
The UNESCO file on tom yum kung is less about what goes in the pot than about who makes it, why, and how it will be kept alive. Its keepers are the Buddhist riverside communities of the Central Plains, along with chefs and cooks. The knowledge moves from home kitchens into schools, and the work ahead is looking after the rivers and the herbs. Next time you have a bowl, there is a whole river behind it.

FAQ
Does every tom yum kung now have to follow one official recipe?
No. UNESCO does not certify recipes. It inscribed the knowledge, skills and practice that communities pass on, so homes and cooks still make it their own way.
Is it the same as World Heritage?
No. World Heritage covers places such as monuments. Intangible cultural heritage covers knowledge and practices people hand down, such as performances, festivals or food. They fall under different conventions.
Does creamy tom yum count too?
The file does not separate clear from creamy. It describes a taste that is sweet, sour, salty, spicy, creamy and slightly bitter. How the two styles differ is covered in the clear-vs-creamy article.
Ingredients and heat vary by kitchen and recipe. If you have a food allergy, ask before you order, every time.
