Food Truck Allergen Labeling: FDA Compliance Guide

FDA Allergen Labeling Requirements for Food Trucks

Under FALCPA, food trucks must clearly label or disclose all major allergens in plain language on menus, signage, or item descriptions. The allergen statement must appear in a separate "Contains" line or be highlighted visibly—not buried in fine print. For items prepared on-site, you must disclose both intentional ingredients and potential cross-contamination risks (e.g., "Contains: Peanuts. Prepared in a facility that also processes milk and shellfish"). State and local health departments often enforce additional requirements; some jurisdictions mandate allergen menus, training documentation, and separation of allergen zones. The FDA does not require "may contain" statements, but many states and municipalities do, making compliance with local regulations essential for food truck operators.

Common Allergen Labeling Mistakes Food Trucks Make

Many food truck operators assume verbal communication about allergens is sufficient—it isn't. Staff turnover, language barriers, and high-volume orders create gaps where allergen information gets lost. A common mistake is listing only primary allergens while omitting cross-contamination warnings; if your fryer shared oil or your cutting board touches multiple proteins, you must disclose that risk. Another critical error is using vague language like "may contain traces"—the FDA and state agencies require specific allergen names. Updating menus inconsistently when recipes change is a frequent compliance failure; if a supplier switches brands or you add new toppings, your allergen disclosures must update immediately. Lack of staff training is perhaps the biggest vulnerability; staff must know which allergens are in every item and how to communicate them accurately.

Best Practices for Allergen Compliance in Food Trucks

Create a detailed allergen matrix for every menu item, documenting all ingredients and potential cross-contamination risks from shared equipment, utensils, and prep surfaces. Post a laminated allergen reference guide in your kitchen and require staff to review it during onboarding and quarterly refreshers. Use POS systems or digital menus that flag allergen items automatically and train staff to verbally confirm allergen information with every customer who asks. Implement color-coded prep zones or dedicated utensils for high-allergen items to prevent cross-contamination. Document all allergen communications and staff training in writing; health inspectors and plaintiffs' attorneys will request these records. Monitor ingredient supplier changes and update your allergen matrix within 24 hours of any recipe modification. Consider implementing a real-time food safety platform that tracks FDA and state allergen enforcement trends and alerts you to regulatory changes in the jurisdictions where you operate.
