Natasha's Law came into force on 1 October 2021. Its purpose was specific: to require full ingredient and allergen labelling on all food pre-packaged for direct sale — sandwiches, wraps, salads and similar items made on the premises and sold from the same site. The law came after the death of Natasha Ednan-Laperouse in 2016, whose fatal allergic reaction to sesame in a Pret A Manger baguette exposed a gap that everyone in the food industry knew about and no one had closed.
Four and a half years later, allergen-related withdrawals and recalls remain the leading category of food safety alerts issued by the Food Standards Agency. They are not the second most common. They are the most common. By a margin.
This week's FSA allergy alert for THIS™ Isn't Chicken Deli Pieces — undeclared soya and wheat in a widely distributed plant-based product — is one data point in a trend that the sector has not yet reversed.
What the Data Shows
The FSA publishes all food and product recalls at food.gov.uk. Allergen alerts — issued when a food product is found to contain an undeclared allergen — consistently account for the largest share of that published activity. The products involved span every food category: confectionery, ready meals, bakery items, sauces, snacks, free-from products and, increasingly, plant-based alternatives.
The pattern matters because the entire premise of Natasha's Law — and the broader allergen labelling framework under UK Food Information Regulations — is that correct labelling allows people with allergies to make safe choices. When labelling is wrong, that framework collapses. The consumer who checked the label and ate the product anyway is not at fault.
Why Recalls Keep Happening
The reasons are consistent across alerts. Reformulation without label update is the most common: a supplier changes an ingredient or a processing facility without regenerating packaging or updating the product specification. Cross-category contamination through shared manufacturing lines is the second: a product manufactured on equipment that also handles nuts, soya or cereals may carry a risk not reflected on the label. Rapid new product development cycles are a growing factor, particularly in plant-based and free-from categories where brands iterate quickly and operational controls don't always keep pace.
A structural issue in the plant-based sector is worth naming directly. Products marketed as "vegan" carry an implicit consumer expectation of being free from animal-derived allergens — milk, eggs, fish. But soya, wheat, nuts and sesame are all both major allergens and common plant-based ingredients. A consumer with a soya allergy buying a "vegan" product may reasonably assume it is safe without reading the label carefully. When it isn't, the consequences are predictable.
What Operators Can Control
Hospitality businesses cannot audit every supplier's manufacturing line. But they can do several things that the data suggests many are not:
Require written allergen declarations for every ingredient, not just product specifications. Specifications describe intended formulation. Written declarations — signed by the supplier — confirm the actual product, and create a paper trail if formulation changes.
Build a trigger into supplier onboarding and renewal that requires allergen re-declaration whenever a product is reformulated or its source manufacturing facility changes. Without this trigger, a supplier can change their product without telling you and your allergen matrix becomes incorrect overnight.
Audit your free-from and plant-based lines specifically. These products attract consumers who are most likely to rely on label information to manage a serious medical risk. Errors here carry the highest consequence.
Keep front-of-house staff updated in real time. An allergen matrix that is accurate in the kitchen but three months out of date on the table card is not a compliant system — it is a liability.
Natasha's Law was never going to solve the problem alone. It closed one gap. The gap that remains is not regulatory — it is operational. And it is the sector's responsibility to close it.
