Allergen Matrix: What It Is, How to Create One & Free Template

An allergen matrix is a table with your menu items listed down the left side and the 14 allergens listed across the top. Each cell is marked to show whether that allergen is present in that dish: typically "Y" for yes (contains), "M" for may contain (cross-contact risk), and blank for not present. Some businesses use symbols, colours, or tick marks instead. The matrix serves multiple purposes. For staff, it is a quick-reference tool to answer customer allergen queries during service. For management, it is the output of your allergen risk assessment, proving that you have assessed every dish against every allergen. For EHOs, it is evidence of due diligence and a structured approach to allergen management. For customers, it provides the specific allergen information they need to make safe choices. Without a matrix, your allergen communication relies on individual knowledge, which is unreliable. With a matrix, any trained team member can answer any allergen question in seconds.

Creating a matrix is straightforward. Keeping it accurate is where most businesses fail. Your matrix becomes inaccurate the moment a recipe changes, a supplier changes a formulation, a new dish is added, or an ingredient is substituted. Build a maintenance process: assign one person as the matrix owner, responsible for all updates. Require that any recipe change is communicated to the matrix owner before the changed dish is served. Check supplier specifications at goods-in and flag any changes. Review the entire matrix at least monthly, and always when the menu changes. Version-control the matrix: date each version and keep a log of changes. When you print a new version, collect and destroy all copies of the previous version. An outdated matrix on a kitchen wall is more dangerous than no matrix at all, because staff trust it and act on incorrect information.
