Allergen Management & Natasha's Law: UK Compliance Guide
Understand UK allergen regulations including Natasha's Law. Learn about the 14 major allergens, labelling requirements, and how to prevent cross-contamination in your food business.
Allergen management is one of the most critical aspects of food safety. With food allergies affecting approximately 2 million people in the UK, and allergic reactions causing around 10 deaths per year, proper allergen control isn't just a legal requirement—it's a matter of life and death.
Understanding Natasha's Law
Natasha's Law came into force on 1st October 2021, named after Natasha Ednan-Laperouse who tragically died from an allergic reaction to sesame in a pre-packed sandwich in 2016. The law requires all food businesses to provide full ingredient lists with clear allergen labelling on foods pre-packed for direct sale (PPDS).
PPDS refers to food that is packaged at the same premises from which it is sold, before being offered to consumers and without any further packaging. This includes items like sandwiches made and wrapped in a cafe, salads packaged in a deli, or baked goods wrapped in a bakery.
The 14 Major Allergens
UK and EU food law identifies 14 major allergens that must be declared when used as ingredients:
Celery — including celeriac
Cereals containing gluten — wheat, rye, barley, oats
Crustaceans — prawns, crab, lobster
Eggs
Fish
Lupin
Milk — including lactose
Molluscs — mussels, oysters, squid
Mustard
Nuts — almonds, hazelnuts, walnuts, cashews, pecans, Brazil nuts, pistachios, macadamia
Peanuts
Sesame seeds
Soybeans
Sulphur dioxide and sulphites — at concentrations above 10mg/kg or 10mg/L
Labelling Requirements
Different rules apply depending on how food is sold:
Pre-packed Food
Must have a full ingredients list with allergens emphasised (typically in bold, italics, or capitals). This applies to food packaged elsewhere before sale.
Pre-packed for Direct Sale (PPDS)
Under Natasha's Law, PPDS food must also have a label with the product name and full ingredients list with allergens emphasised. The label must be attached to the packaging.
Non Pre-packed (Loose) Food
Allergen information must be available to customers. This can be provided verbally, but there must be clear signage directing customers to ask staff, and staff must be properly trained to provide accurate information.
Preventing Cross-Contamination
Even trace amounts of allergens can trigger severe reactions. Preventing cross-contamination requires careful attention to:
Storage — keep allergenic ingredients separately identified and stored
Preparation areas — clean thoroughly between preparing different dishes
Equipment — use separate utensils for allergen-free preparation where possible
Cooking — be aware of shared cooking oils, grills, and fryers
Service — ensure front-of-house staff can communicate accurately with kitchen
Staff Training
All staff who handle or serve food need allergen awareness training. They should understand the severity of allergic reactions, know the 14 major allergens, be able to identify which dishes contain allergens, understand cross-contamination risks, and know what to do if a customer has an allergic reaction.
Managing Allergen Information
Maintain accurate, up-to-date allergen information for all dishes. This should be reviewed whenever recipes change, new suppliers are used, or new menu items are introduced. Many businesses use allergen matrices or digital systems to track this information systematically.
