South Korea Food Allergy
Travel Guide

Eating your way through Seoul with a food allergy means knowing which dishes hide seafood. Kimchi is often made with salted shrimp or anchovy, though products and restaurants vary. Gochujang raises soy and wheat questions, while sesame, sauces, and shared grills can affect the rest of the meal. This hub explains what to ask, how packaged labels differ from restaurant communication, and how to carry it all in Korean.

Direct answer: Many kimchi recipes contain jeot, such as salted shrimp or fermented anchovy, but you need to ask about the exact product or restaurant recipe. Gochujang commonly raises soy and wheat questions; it does not answer whether a whole dish contains seafood or has shared-equipment contact. Read packaged labels, show a Korean-language card at restaurants, ask about stock, sauces, and tools, and skip anything staff cannot explain.
The recurring Korean food questions: Ask about soy in ganjang and doenjang, sesame oil and seeds in banchan and garnishes, jeot in kimchi, wheat in gochujang and processed foods, and fish or shellfish in broths and sauces. Packaged labels can help when you can read the current information; restaurant communication still requires a written Korean-language card and direct questions.

Key allergen questions in South Korea

Soy, sesame, wheat, and fermented seafood appear in many Korean recipes, so each dish needs its own ingredient and preparation check.
Allergen profile
Soy: the foundational seasoning

Ganjang (soy sauce), doenjang (fermented soybean paste), and often gochujang raise soy questions. Ask about marinades, sauces, banchan, tofu, and shared tools rather than relying on an unmarinated main ingredient alone.

Allergen profile
Sesame: the universal finish

Sesame oil and seeds are common in banchan, namul, sauces, garnishes, and gimbap. Ask about the oil, toppings, shared utensils, and cooking surface at every meal.

Allergen profile
Jeot: shellfish in kimchi

Many kimchi recipes use jeot, such as saeujeot (salted shrimp) or myeolchi-jeot (fermented anchovy). Ask about the exact batch, fish sauce, shared serving tools, and whether a vegan version still contains soy or sesame.

Allergen profile
Wheat: in sauces and processed foods

Gochujang may contain wheat, and wheat also appears in ramyeon, fried chicken batter, snacks, and some sauces. Check the exact product or recipe; do not treat a glass-noodle dish as free from soy, sesame, or shared-wok contact.

Communicating your allergy in Korea

South Korea's allergen labeling system applies to packaged food, not restaurants. For restaurant communication, put it in writing rather than trying to say it. A Korean-language card reaches kitchen staff directly and uses the correct Korean terminology for each allergen.

Key Korean allergen vocabulary: 간장 (ganjang, soy sauce) · 된장 (doenjang, soybean paste) · 참깨 (chamkkae, sesame) · 새우젓 (saeujeot, salted shrimp) · 밀 (mil, wheat) · 우유 (uyu, milk) · 달걀 (dalgyal, egg) · 땅콩 (ttangkong, peanut) · 생선 (saengseon, fish). A Korean-language allergy card that includes these terms is more reliable than phonetic pronunciation.

South Korea's packaged-food labeling

South Korea's Ministry of Food and Drug Safety provides current allergen-labeling information for packaged food. Use the label on the exact product in front of you; product formulas and label guidance can change, and a packaged-food label does not explain how a restaurant manages shared preparation.

Category Allergens
Standard (shared with most countries) Egg, milk, buckwheat, peanut, soy, wheat, mackerel, crab, shrimp, pork, peach, tomato, sulfites
Additional foods in Korea's 22-item list Walnut, chicken, beef, squid, clams (including oyster, abalone, mussel), pine nuts

This information is useful for packaged food sold in supermarkets, convenience stores, and online retail. Restaurants are a different setting: ask about the recipe, sauce, stock, oil, utensils, and shared surfaces directly. A written card helps communicate the allergen, but it is not proof that the kitchen can prevent cross-contact.

Note on sesame: sesame is not one of the 22 foods in the MFDS's dedicated allergen-labeling list. Read the full current ingredient list on packaged food, and ask separately about sesame oil, sesame seeds, garnishes, and shared tools for prepared food.

Korean dishes: what to ask before ordering

Dish Key allergens Notes
Kimchi (김치) Shellfish (salted shrimp), fish (fish sauce) Ask about saeujeot, aekjeot, fish sauce, the exact batch, and shared serving tools.
Doenjang jjigae (된장찌개) Soy (doenjang), shellfish/fish (anchovy broth base) Doenjang is the soy ingredient; ask whether the broth contains anchovy, shellfish, or another stock.
Bibimbap (비빔밥) Soy (gochujang sauce), sesame oil, egg Ask about gochujang, sesame oil, egg, seasoned vegetables, protein, bowl, and shared utensils.
Tteokbokki (떡볶이) Soy (gochujang), wheat (soy sauce in sauce) Ask about gochujang, wheat, soy sauce, fish cake, broth, and shared serving tools.
Japchae (잡채) Soy (soy sauce), sesame oil, sesame seeds, egg Ask about soy sauce, sesame oil and seeds, egg, the wok, and shared utensils.
Bulgogi / galbi (불고기/갈비) Soy (marinade), sesame, sometimes pear or apple (cross-reactive with birch pollen) Ask about the marinade, sesame, grill, tongs, and whether the restaurant can use clean equipment.
Plain samgyeopsal (삼겹살) Pork; recipe and preparation still need confirmation Ask whether it is unmarinated and whether the grill, tongs, sauces, and serving tools are shared.
Sundubu jjigae (순두부찌개) Soy (silken tofu), shellfish (common additions), fish (anchovy broth) Ask about tofu, anchovy or seafood broth, seafood additions, gochugaru paste, and shared pots.
Gimbap (김밥) Sesame oil (rice is seasoned with it), soy, egg, fish (tuna or crab stick fillings) Ask about sesame in the rice, soy in fillings or sauce, egg, fish, crab stick, and shared boards.
Plain rice (흰 쌀밥) Rice; preparation still needs confirmation Ask whether the rice is plain and whether the serving utensil or cooker is shared.

Korean BBQ with a food allergy

Korean BBQ (samgyeopsal, bulgogi, galbi) can make the main ingredient visible, but cooking at the table does not remove questions about marinades, grills, tongs, banchan, sauces, and other diners' food:

  • Marinades: Bulgogi and galbi commonly use soy sauce and sesame, but ask about the exact recipe. If you order plain pork belly, confirm that it is unmarinated.
  • Shared grills: If the restaurant serves seafood on the same grill, cross-contamination is a real risk. Ask for a clean grill plate (새 불판 주세요: sae bul-pan ju-se-yo: please give me a new grill pan).
  • Banchan (side dishes): Ask about sesame oil, soy, kimchi, jeot, fish, and shared serving utensils for each dish.
  • Dipping sauces: Ssamjang usually involves doenjang and gochujang, so ask about soy, wheat, sesame, and the serving utensil. Plain salt may still need a clean utensil.
A possible Korean BBQ plan: Ask for an unmarinated cut, a clean grill plate and tongs, no sauce on the meat, and an explanation of any banchan or sides. Plain rice or salt may be useful only after the restaurant confirms the preparation.

Getting around South Korea

Managing an allergy on the move is easier when you control your own schedule rather than a shared group timetable, especially around meal timing and medication. Search trains, buses, and ferries between Korean cities below.

Emergency information for South Korea

  • Emergency number: Call 119 for a medical emergency or ambulance in South Korea.
  • Police: 112
  • During a reaction: Follow your personal action plan and use prescribed emergency medication as directed. Do not delay care while trying to identify a particular hospital or pharmacy.
  • Before travel: Save the address of the nearest emergency department, keep medication in your carry-on or day bag, and verify current hospital intake and language information before relying on it.
  • Key emergency phrase: Show a written Korean-language card stating the allergen and seriousness. A card is more reliable than trying to pronounce a medical phrase during a reaction.

Travel insurance

Check three things before you buy a policy for a South Korea trip: does it cover emergency anaphylaxis treatment, does it exclude food allergies as a pre-existing condition, and does it include medical evacuation with a clear coverage limit if you're traveling to more remote areas.

Confirm that your chosen policy covers emergency treatment for an allergic reaction before purchase. Coverage for anaphylaxis, pre-existing conditions, evacuation, and other benefits depends on the current policy wording and your eligibility.

Frequently asked questions

Is South Korea safe for travelers with food allergies?

South Korea requires allergen labeling for 22 specified foods and ingredients in packaged food, including egg, milk, buckwheat, peanut, soy, wheat, fish, crustaceans, walnuts, chicken, beef, squid, clams, and pine nut. That can make a current package label useful when you can read it, but it does not establish that a restaurant can accommodate an allergy or prevent cross-contact. At restaurants, ask about the exact recipe, sauces, stock, and preparation tools; soy-based seasonings, sesame, and fermented seafood are examples of ingredients worth checking in many Korean dishes.

What are the biggest allergen risks in Korean food?

Questions commonly worth asking in Korean food include soy in ganjang and doenjang, sesame oil or seeds in seasoned side dishes, fish or shellfish in kimchi seasoning and broth, and wheat in sauces or processed foods. Gochujang formulations vary, so check the specific product or restaurant sauce for soy and wheat rather than assuming one recipe. Glass noodles are commonly made from sweet-potato starch, but the finished dish can still contain other allergens through its sauce and preparation.

Does kimchi contain shellfish?

Many kimchi recipes use seafood seasoning, such as saeujeot (salted shrimp) or myeolchi-jeot (fermented anchovy), so kimchi may be unsuitable for a shellfish or fish allergy. Recipes vary by product, restaurant, and batch; ask what was used in the specific kimchi and do not assume that a vegan or seafood-free version is available. Ask specifically: 'Kimchi-e saeujeot deureo innayo?' (Does the kimchi contain salted shrimp?) The Korean term to carry in writing is 새우젓 (saeujeot).

Does kimchi contain peanuts or tree nuts?

Peanuts and tree nuts are not standard kimchi ingredients, but a specific product or restaurant recipe can vary. For packaged food, read the current ingredient and allergen information; for a restaurant, ask about the exact recipe and preparation. The Korean word for peanut is 땅콩 (ttangkong), which is best carried in writing on an allergy card.

Does gochujang contain shellfish?

Gochujang itself is not ordinarily a seafood paste, but its ingredients vary by brand and recipe. Check the specific paste or restaurant sauce for soy and wheat, and ask separately whether the finished sauce includes seafood stock, anchovy, or other additions. A dish containing gochujang is not automatically free of fish or shellfish.

How do I say food allergy in Korean?

The core phrase is 'Jeoneun [allergen]-e allereugi ga isseoyo' (저는 [allergen]에 알레르기가 있어요), I have an allergy to [allergen]. Carry the allergen word in writing and ask staff to confirm the ingredients and preparation. At a barbecue table, '새 불판 주세요' asks for a new grill plate. For severity, use the written phrase 이 알레르기는 생명을 위협할 수 있습니다 (This allergy can be life-threatening). In an emergency, 아나필락시스 증상이 있어요. 119 불러 주세요 means I have symptoms of anaphylaxis. Please call 119.

Can you eat Korean BBQ with a food allergy?

Korean BBQ can make the main ingredient easier to identify, but it does not make a meal safe by default. If pork is compatible with your own restrictions, ask whether a cut is unmarinated and whether the restaurant can provide a clean grill plate, tongs, and serving tools. Ask about every banchan and sauce, including soy-based pastes, sesame, and kimchi seasoning. Choose a different meal if the restaurant cannot explain the ingredients or separate preparation.
