Natasha's Law Allergen Compliance: The POS Features That Keep You Legal

What Natasha's Law actually requires#

Natasha's Law requires full ingredient lists and allergen labelling on all food that is pre-packed for direct sale (PPDS) — food that is packaged on the same premises where it is sold. This includes: sandwiches and wraps made in a café before the customer arrives, baked goods pre-packaged on the premises, boxed salads made up before sale, any food that is wrapped before the customer orders. For food made to order (most restaurant meals), the legal requirement is to provide allergen information on request — either verbally or in writing. The critical risk point is for restaurants that also sell PPDS products: a patisserie that pre-packs pastries, a café that pre-wraps sandwiches, a restaurant that sends pre-made meals for delivery packaged in advance.

The 14 major allergens every restaurant must track#

UK law requires restaurants to be able to identify and communicate the presence of 14 major allergens in any dish: celery, cereals containing gluten (wheat, rye, barley, oat, spelt), crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soybeans, sulphur dioxide and sulphites (above 10mg/kg), and tree nuts (almond, hazelnut, walnut, cashew, pecan, Brazil, pistachio, macadamia). Every recipe in your kitchen must have its allergen composition documented. This is not optional — it is a legal requirement, and the Environmental Health Officer will ask for it during a hygiene inspection.

How AskBiz tracks allergens at recipe level#

When you enter a recipe in AskBiz, you assign allergen flags to each ingredient. Milk in the recipe flags as dairy. Wheat flour flags as gluten. AskBiz aggregates the allergen flags across all ingredients in a dish to produce a dish-level allergen summary. This summary is visible: at the POS when a server looks up a dish, on your printed menu if you connect AskBiz to your menu design template, and in the kitchen on the KDS when a modifier is added (e.g., "swap cream for oat milk" removes the dairy flag but adds any oat allergen). When a guest tells the server they have a nut allergy, the server can check every dish in the order for nut allergens in seconds — without going to the kitchen.

Modifications and allergen risk at the point of service#

Allergen risk peaks at the modification point — when a customer requests a substitution that they believe removes an allergen but does not. A customer with a milk allergy asks for "no cheese" on a pasta dish. The server removes the cheese from the order. But the pasta sauce was made with cream — dairy is still present. Without allergen tracking that updates at modification level, the server cannot know this. AskBiz flags allergen implications of every modification: if removing cheese leaves other dairy ingredients in the dish, the server sees an alert: "Dish still contains: Milk (cream in sauce)." This alert has prevented allergic incidents in restaurants using the system — not just compliance ticks.

Staff training and the digital allergen record#

Staff training on allergens is a legal requirement in the UK — not just best practice. Every food handler and front-of-house employee must understand the 14 allergens and the risk of cross-contamination. AskBiz provides a staff training module with allergen certification built in: staff complete an online allergen awareness course through the system and their completion is logged with a date stamp. During an Environmental Health inspection, you can demonstrate both the allergen record for every dish and the allergen training record for every employee. This documentation is increasingly expected by inspectors and can make the difference between a 5-star and 4-star hygiene rating.

Cross-contamination management#

Documenting allergens in recipes addresses the intended composition of a dish. Cross-contamination — where an allergen-free dish picks up allergens through shared preparation surfaces, utensils, or cooking equipment — is a separate and equally important risk. AskBiz's kitchen management module allows you to document cross-contamination protocols: which preparation stations handle nut-containing ingredients (and therefore cannot be used for nut-free dishes without cleaning), which utensils are designated allergen-free, what the cleaning protocol is between allergen and allergen-free preparation. These protocols can be attached to specific dishes as kitchen notes that appear on the KDS, reminding the chef of cross-contamination requirements when a dish with allergen flags is ordered.

The consequence of getting it wrong#

Natasha Ednan-Laperouse died in 2016 after eating a Pret a Manger baguette containing sesame, to which she was severely allergic. The baguette had no allergen label. Her death led directly to Natasha's Law. The consequences of allergen non-compliance are not administrative — they are human. A criminal prosecution under the Food Information Regulations can result in unlimited fines. Civil liability for an allergic reaction caused by inadequate allergen information is also unlimited. A 5-star restaurant with an untracked allergen error can face consequences that no insurance policy covers in full. The operational cost of allergen compliance through a system like AskBiz is approximately £0 on top of your existing subscription. The cost of non-compliance is incalculable.

• Natasha's Law, effective October 2021, has created significant allergen compliance requirements for UK food businesses — including restaurants.
• Non-compliance can result in criminal prosecution, unlimited fines, and — most critically — preventable allergic reactions.
• AskBiz tracks all 14 mandatory allergens at recipe level and flags risks at the point of sale.
