Chicago Allergen Labeling & Disclosure Requirements for Restaurants

Federal FDA Allergen Labeling Standards

The FDA's Food Allergen Labeling and Consumer Protection Act (FALCPA) requires manufacturers and food service establishments to clearly label nine major allergens: milk, eggs, peanuts, tree nuts, fish, crustacean shellfish, soy, wheat, and sesame. For Chicago restaurants, this means pre-packaged foods and menu items must disclose these allergens in plain, easily understood language. The FDA defines "major allergens" by their prevalence in allergic reactions and requires labeling even when allergens appear in trace amounts from shared equipment or preparation surfaces. Chicago-based restaurants selling food across state lines or through multi-location chains must align with FALCPA standards.

Illinois State Allergen Disclosure Requirements

Illinois Public Act 98-377 mandates that restaurants provide written allergen information upon customer request. The Illinois Department of Public Health (IDPH) requires restaurants to maintain allergen information for all menu items and be prepared to share this data with customers before service. Unlike federal law, Illinois regulations specifically require verbal and written notification capabilities—restaurants cannot simply list allergens on a menu board alone. Illinois also requires that establishments maintain ingredient documentation from suppliers and train staff to accurately communicate allergen risks. The law applies to all food service establishments in Chicago, including casual dining, fast-casual, and fine dining venues.

Chicago Local Regulations & Health Department Requirements

The Chicago Department of Public Health enforces stricter allergen protocols than federal standards. Chicago's Municipal Code Title 41, Chapter 41-24 requires restaurants to identify allergens on menus and maintain detailed allergen matrices for all menu items. The city mandates that restaurants separate allergen-containing foods during storage and preparation, with documented protocols for cross-contact prevention. Chicago health inspectors verify allergen training records during routine inspections and can cite violations ranging from $250 to $2,500 per infraction. Additionally, Chicago requires written acknowledgment from customers ordering allergen-containing items, and restaurants must document these acknowledgments for liability protection.
