Why Wiping a Surface Does Not Remove an Allergen
Cross-contact is the transfer of an allergenic protein from one food to another, and it is not the same problem as bacterial contamination. Heat does not destroy it, a service cloth spreads it, and for some people a reaction starts at traces measured in milligrams. The controls that work are separation and replacement, not cleaning.
The quantity involved can be far below anything visible, which is why experienced kitchen staff get this wrong more often than new ones. A cook with strong hygiene habits reasonably assumes a clean surface is a safe surface, and applies a standard that works for pathogens to a problem it does not solve. What stays out of the published version is a promise of an allergen-free kitchen: a shared production space cannot guarantee absence, and a video that implies otherwise creates a liability the operation cannot meet.
This template covers the subject in seven scenes: one defining cross-contact against ordinary contamination, one on the major allergens the operation handles, two on the separation rules for boards, utensils, oil, and hands, one on the order in which an allergy ticket is prepared, one on labelling and handover to the front of house, and one on what to say when absence cannot be guaranteed.
