An allergy request begins before the plate
A surface can look clean without answering an allergy question. FDA research shows why the cleaning method and the food involved both matter.
FDA

Beyond appearances
An FDA study examined the removal and transfer of peanut, milk, and egg foods on several surface materials. Cleaning performance varied with the food, surface, and wiping conditions. Full cleaning performed effectively under the study’s conditions.
The distinction matters because a quick wipe and a complete cleaning process are different actions. A visual impression cannot tell a cook everything about what remains on a surface.
Connect the guest request to the kitchen
An allergy request brings together ingredient information, preparation choices, communication, and the operation’s approved procedures. Uncertainty at any point deserves attention before reassurance reaches the guest.
The study helps explain why confidence needs a process behind it. It does not establish that a particular kitchen is allergen-free or verify a local method. The useful perspective is to look beyond the final plate and consider how information and handling connect throughout the request.
