Dietary preference and medical allergy are handled as the same line on most booking forms, and they are not the same thing. Vegetarian, vegan and halal requirements are about what a client will eat; a severe allergy is about what will put them in hospital. Across all four of Explera's destinations the systems that serve the first do very little for the second, and the gap is where these files go wrong. This is the operating standard an agent should expect from any ground handler in the region, and the questions that reveal whether they have one.
La règle valable sur les quatre marchés
Packaged food is regulated. Restaurant food is not — or not nearly to the same degree.
Every one of our four destinations has some form of allergen declaration requirement for pre-packaged products, with varying lists and varying enforcement. None of them extends that obligation in full to a meal cooked and served on the premises. A printed restaurant menu carries no equivalent duty to tell a client what is in the dish.
This inverts the assumption most travellers arrive with. A labelled product from a convenience store or a department-store food hall is frequently the safest item available on a travel day, and the tasting menu at the property the agent was most proud of booking is the hardest to verify. An operator that understands this builds the itinerary around it rather than apologising for it later.
Les ingrédients cachés, marché par marché
The specific traps differ, and a briefing that does not name them is not a briefing.
Japan. Dashi — stock made from dried bonito — is in soups, sauces, dressings, simmered dishes and egg dishes that contain no visible fish. Soy sauce contains wheat almost universally. Buckwheat is both a major allergen and a staple, which makes cross-contact in a soba restaurant effectively unavoidable. Our Japan food allergy guide sets the detail out in full.
Corée. Shellfish and fermented seafood appear in side dishes and seasoning pastes well beyond the obvious, and the shared-banchan service model means the table itself is a cross-contact environment. Sesame and peanut are widespread in sauces.
Thaïlande. Fish sauce and shrimp paste are foundational to dishes that read as vegetable-based, and peanut is used far more widely than in the dishes clients associate with it. This is the market where "no seafood" most often fails in practice.
Indonésie. Peanut is structural to major sauces, shrimp paste is used across the cuisine, and coconut is pervasive in a way that matters for a small but real group of clients.
The common thread: in all four markets, the allergen is usually in the seasoning rather than in the visible ingredient, which is exactly what a client scanning a plate cannot detect.
Le standard : six choses que fait un opérateur compétent
1. Collects medical detail in writing at booking — the specific allergen, the severity, whether trace exposure is a risk, and whether the client carries an adrenaline auto-injector. "No nuts" from a form is not usable. 2. Issues a written allergy card in the local language, naming the allergen and stating that trace amounts matter, designed to be handed to the kitchen rather than relayed by floor staff. 3. Briefs venues days ahead, not at the table. Set menus, banquet service and fixed multi-course dinners are built in advance; notice on arrival produces a plain substitute at best. 4. Accepts refusal as a good answer. A kitchen that declines to guarantee a dish is behaving responsibly. The correct response is to change venue, not to press. 5. Maps the medical layer per overnight stop — nearest capable hospital, emergency numbers, and the insurance position, which matters more the further a programme gets from a major city. 6. Tells the agent which parts of the itinerary cannot be made safe. Street-food programmes, communal cooking formats and shared-grill venues frequently cannot, and saying so early is the service.
Là où cela se complique et là où cela s'allège
Harder: rural properties with fixed multi-course menus; small owner-operated restaurants with no written ingredient records; food tours and street-food programmes, where sampling is the entire product; and any venue where the meal is cooked communally or on shared equipment.
Easier: international hotel restaurants; larger modern chains with printed allergen matrices; packaged retail, where the labelling regime applies in full; and private-dining arrangements where the chef is briefed as a requirement rather than an exception.
A well-built file for a severe allergy across any of the four markets usually looks like hotel breakfasts, one or two properly briefed dinners, and the rest of the client's eating built around food they can verify themselves. That is a less romantic itinerary than the brochure promises. It is also the one that does not end in an ambulance, and an agent who explains that trade-off to a client is doing better work than one who promises the brochure.
The adjacent preference-based requirements sit in our halal-friendly travel guide, and our full ground-handling capability in the services overview.
Questions fréquentes
Do Asian restaurants have to declare allergens? Generally no. Across Japan, Korea, Thailand and Indonesia the declaration requirements apply to pre-packaged food rather than to meals cooked and served on the premises, so a menu carries no equivalent obligation.
What is the most common cause of accidental exposure? Seasoning. Dashi in Japan, fermented seafood pastes in Korea, fish sauce and shrimp paste in Thailand and Indonesia, and peanut across Southeast Asia all appear in dishes with no visible trace of the allergen.
What should an agent collect at booking? The specific allergen, the severity, whether trace exposure is a risk, and whether the client carries an auto-injector — in writing. A general note such as "seafood allergy" cannot be used to brief a kitchen.
Will restaurants in the region accommodate severe allergies? Many will, when briefed several days ahead. Some decline rather than accept the risk, which is a responsible answer. The right response is to change venue rather than to insist.
Can a client with a severe allergy join a food tour? Often not safely. Street-food and tasting programmes are built on sampling items nobody can fully specify, and that should be said at quote stage rather than managed on the day.
