Quick Answer

A food allergen QR code provides restaurant guests with immediate access to a complete digital matrix covering all 14 EU/UK or 9 US FDA mandated food allergens. While streamlining updates when ingredients change, food regulations require pairing QR disclosures with visible signage and verbal staff communication.

Frequently Asked Questions

No. Under UK FSA and EU FIC regulations, a QR code is considered an auxiliary tool. Restaurants must also display a visible physical sign directing customers to allergen information, provide verbal confirmation on request, and make a non-digital printed copy available for guests without smartphones.

Natasha's Law (enacted in the UK in October 2021) requires foods Prepacked for Direct Sale (PPDS)—such as pre-made sandwiches or salads packaged on-site before ordering—to have full physical ingredient labels with allergens emphasized on the package. A QR code alone is not legally sufficient for PPDS items.

The URL and QR code itself never need to change. However, the data hosted at that URL must be updated immediately whenever a recipe is altered, a new dish is introduced, or a supplier substitutes an ingredient containing different allergens.

While allergen icons are helpful visual aids, food safety authorities recommend accompanying all icons with explicit text labels (e.g., 'Contains: Peanuts, Gluten') to prevent misinterpretation by customers with visual impairments or unfamiliarity with custom icon sets. Keep a readable destination or contact route nearby so users still have an option when scanning is unavailable.
