South Korea Food Allergy Hub
South Korea has Asia's most comprehensive mandatory allergen labeling system: 22 allergens, all declared on packaged food. The practical challenge for travelers is that soy sauce underlies virtually every Korean dish, sesame oil is the standard finishing element, and traditional kimchi contains fermented seafood. This hub collects every AllergyPass guide for Korea.

Key allergen risks in South Korea
Ganjang (soy sauce) and doenjang (fermented soybean paste) are used as salt equivalents across Korean cooking. Gochujang also frequently contains soy. Unmarinated grilled meat and plain rice are the safest baseline for soy allergy.
Sesame oil is added to virtually every banchan (side dish), namul (seasoned vegetable), and many main dishes as a finishing element. Sesame seeds coat mayak gimbap and appear on many bread and pastry products. Sesame allergy requires flagging at every meal.
Traditional kimchi is made with jeot, fermented seafood paste. Most commonly saeujeot (salted shrimp) or myeolchi-jeot (fermented anchovy). Many restaurants now offer vegan kimchi as an alternative. Ask: "Kimchi-e saeujeot deureo innayo?"
Gochujang (the base of tteokbokki and bibimbap sauce) often contains wheat flour as a thickener. Ramyeon (instant noodles), fried chicken batter, and many processed snacks contain wheat. Glass noodles (dangmyeon) are sweet potato starch and gluten-free.
Communicating your allergy in Korea
South Korea's allergen labeling system applies to packaged food, not restaurants. For restaurant communication, a written Korean-language card is the most effective tool because it reaches kitchen staff directly and uses the correct Korean terminology for each allergen.

Frequently asked questions
Is South Korea safe for travelers with food allergies?
South Korea has Asia's best mandatory allergen labeling system for packaged food. For restaurants, advance communication with a Korean-language written card is essential. The practical risks are soy, sesame, and jeot (fermented seafood in kimchi). Seoul's hospital infrastructure is excellent. With preparation, South Korea is a very manageable destination for most allergy profiles.
What are the biggest allergen risks in Korean food?
Soy is the foundational seasoning across all Korean cooking. Sesame oil is the universal finishing element. Traditional kimchi contains jeot (fermented shrimp or anchovy). Wheat appears in gochujang and many processed snacks. Peanut and tree nut risk is relatively low compared to Southeast Asian cuisines.
Does kimchi contain shellfish?
Traditional kimchi is made with jeot, most commonly saeujeot (salted shrimp) or myeolchi-jeot (fermented anchovy sauce). Both contain shellfish or fish allergens. Vegan kimchi without jeot is increasingly available in Seoul restaurants. Ask specifically: "Kimchi-e saeujeot deureo innayo?" (Does the kimchi contain salted shrimp?)
How do I say food allergy in Korean?
Jeoneun [allergen]-e allereugi ga isseoyo (저는 [allergen]에 알레르기가 있어요): I have an allergy to [allergen]. For severity: i allergy-ga simhameun saengmyeong-e wiheomaul su isseoyo (이 알레르기가 심하면 생명에 위험을 수 있어요): this allergy can be life-threatening. A written Korean-language card from AllergyPass uses the correct terminology and is more reliable than verbal communication.
