Sushi Allergen Safety Guide for Los Angeles

California Allergen Disclosure Laws & LA Requirements

California's Health and Safety Code requires restaurants to disclose major food allergens upon customer request, listing the FDA's Big 9 (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy, and sesame). Los Angeles County Department of Public Health enforces these requirements through health code 113948, mandating written allergen information be available to diners. Many LA sushi restaurants now post allergen matrices on menus or provide ingredient cards identifying cross-contact risks with sesame, which became a priority allergen for CA in 2023. Staff training requirements mean managers must be able to identify sesame, fish, and shellfish risks specific to each roll and sauce.

Common Sushi Allergen Sources & Hidden Risks

Fish and shellfish are obvious sushi allergens, but sesame—present in seeds, mayo-based sauces, and Asian condiments—triggers severe reactions and often goes undeclared on older menus. Soy sauce and mirin contain wheat unless explicitly gluten-free, creating a trap for celiac diners ordering seemingly simple items. Cross-contact in shared prep spaces, cutting boards, and sauce containers is endemic in busy LA sushi bars and sashimi stations. Imitation crab, common in California rolls, contains shellfish allergens despite being advertised as 'crab substitute,' and some establishments use fish-based stocks in rice or dashi broths that aren't always disclosed upfront.
