Allergen Management Flashcards

What is the difference between a food allergy and a food intolerance, and why does this distinction matter for food safety management?

Answer: A food allergy involves the immune system and can cause life-threatening anaphylaxis even from trace amounts; a food intolerance (such as lactose intolerance) does not involve the immune system, is not life-threatening, and is dose-dependent — both require management but allergies demand stricter controls due to the severity of potential reactions

Food allergies trigger an IgE-mediated immune response that can cause anaphylaxis from microscopic amounts of the allergen. Food intolerances (e.g., lactose intolerance, histamine intolerance) involve the digestive system, cause uncomfortable but non-life-threatening symptoms, and are generally dose-dependent (small amounts may be tolerated). This distinction matters for management: allergies require absolute prevention of contact (including trace amounts and cross-contact), while intolerances may allow some flexibility in quantity. However, both must be taken seriously and communicated accurately.

What specific requirements does Natasha's Law place on food that is Prepacked for Direct Sale (PPDS)?

Answer: PPDS food must have a label showing the name of the food and a full ingredients list with the 14 declarable allergens emphasised (e.g., bold, underlined, or capitalised) within the ingredients list — the label must be attached to the packaging before the consumer selects or orders the food

Under Natasha's Law (effective from 1 October 2021), all PPDS food must carry a label with: the name of the food and a full ingredients list with allergens emphasised through typographical means (bold, italics, contrasting colour, or capitalisation — bold being most common). The label must be physically attached to or incorporated into the packaging. PPDS includes food packaged on the same premises from which it is sold, before the customer orders or selects it — e.g., pre-made sandwiches in a deli counter, boxed salads in a cafe.

How should allergen information be communicated in a restaurant or catering environment serving non-prepacked food?

Answer: Allergen information must be provided either through written means (menus, chalk boards, allergen folders, digital displays) or by a clear notice directing customers to ask staff — if using the verbal route, staff must be trained and a written record of allergens in each dish must be available to staff

For non-prepacked food (meals served in restaurants, cafes, canteens), the Food Information Regulations 2014 require allergen information to be available before purchase. This can be: written on the menu next to each dish, displayed on a separate allergen matrix/board, available in an allergen folder/binder, shown on a digital display, or communicated verbally if clear signposting directs customers to ask. If using the verbal route, a documented allergen record for every dish must be available to staff, and staff must be trained and competent to provide accurate information.

What role does supplier management play in allergen control?

Answer: Suppliers must provide accurate, up-to-date allergen information for all ingredients supplied, including any 'may contain' cross-contact risks, changes to formulations must be communicated immediately, and the food business must verify supplier declarations through specifications, questionnaires, and periodic audits

Allergen control begins at the supply chain. Food businesses must: obtain written allergen declarations from all suppliers, request full ingredient specifications, include allergen requirements in purchase specifications, establish a system for suppliers to notify of recipe/formulation changes (which could introduce new allergens), periodically verify supplier declarations through audits or questionnaires, and check ingredient labels on delivery against specifications. A single undeclared ingredient change by a supplier can cause a life-threatening allergic reaction in a consumer.

What cleaning procedures are necessary to prevent allergen cross-contact between food preparation tasks?

Answer: Equipment and surfaces must be thoroughly cleaned between allergen-containing and allergen-free food preparation using hot water and detergent, following the correct cleaning sequence, with visual inspection and ideally validated cleaning methods such as allergen testing swabs to confirm effective allergen removal

Allergen proteins are not destroyed by standard disinfection or heat treatment. Effective allergen cleaning requires: thorough physical cleaning with hot water and detergent (to remove protein residues), following the full cleaning sequence, visual inspection for any remaining food residue, and ideally using lateral flow test kits (allergen swabs) to validate cleaning effectiveness. Dedicated equipment for allergen-free preparation is preferred. Shared deep-fat fryers are a particular risk. Cloths used for cleaning must themselves be clean and free from allergen residues. Documentation of allergen cleaning procedures is essential.

What training should food handlers receive regarding allergen management, and how often should it be refreshed?

Answer: All food handlers must receive comprehensive allergen training covering the 14 declarable allergens, recognition of allergic reactions and anaphylaxis, cross-contact prevention, customer communication procedures, and emergency response — training should be refreshed at least annually and when menu changes occur, with competency assessed and documented

Allergen training for food handlers should cover: the 14 declarable allergens and where they are commonly found, the difference between allergy and intolerance, the severity of allergic reactions including anaphylaxis, how to prevent cross-contact during storage, preparation, and service, how to respond to customer allergen enquiries accurately, how to check recipes/allergen matrices, what to do in an allergic reaction emergency, and the legal requirements. Training should be refreshed annually at minimum, whenever menus change, and when new allergen-containing ingredients are introduced. Competency should be assessed (not just attendance) and documented.
