Allergen management software for UK food businesses

Allergen management software is a category of compliance technology that helps UK food businesses track ingredients, log allergen communications and maintain audit-ready records across the supply chain, from raw material intake to point of sale. 

Natasha's Law sets the legal baseline for allergen labelling, Owen's Law remains guidance rather than statute, and FSA data shows allergen incidents and recalls climbing faster than most other hazard categories.

Closing the gap between what compliance requires and what a business's food safety management software can actually deliver is where dedicated allergen management tools earn their place in a compliance program. 

UK allergen laws: Natasha's Law, Owen's Law and FSA allergen guidance 

Natasha's Law: what it requires 

Natasha's Law has been in force since October 2021, requiring full ingredient labelling with the UK's 14 legally regulated allergens emphasized in bold, italic or underlined text on all pre-packed for direct sale (PPDS) food.

It followed the death of Natasha Ednan-Laperouse, who suffered a fatal reaction to undeclared sesame in a Pret a Manger baguette. For PPDS producers, this makes Natasha's Law compliance software a practical requirement rather than a nice-to-have. 

The 14 regulated allergens are celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soya, sulphites and tree nuts. 

What is Owen's Law, and has it passed? 

Owen's Law is often cited as if it were already in force, but it has not passed. Following the 2017 death of Owen Carey, who was served chicken marinated in buttermilk at a Byron restaurant despite disclosing his dairy allergy, the FSA has campaigned for mandatory written allergen information in cafes, restaurants and takeaways. FSA chair Professor Susan Jebb called on ministers to legislate for this in 2024, but no such legislation has passed.

The FSA has instead issued best-practice guidance recommending written allergen information alongside verbal communication. Businesses should treat it as a strong signal of future direction, not a current legal duty. 

The table below maps this regulatory picture to the specific capabilities allergen management software needs to support it.

Regulation or guidance	Core requirement	Software capability
Natasha's Law (in force since October 2021)	Full ingredient list and emphasized allergen labelling on PPDS food	Ingredient-level traceability linked to formulation data, with automated label generation
FSA best-practice guidance (Owen's Law campaign)	Written allergen information alongside verbal communication in catering settings	Centralized, version-controlled allergen matrix for front-of-house staff
BRCGS, GFSI and ISO 22000-aligned standards	Documented allergen risk assessment and control across every facility and supplier	Supplier audit trails, risk scoring and corrective action tracking
FSA incident and recall expectations	Rapid identification and traceability of affected batches	Batch-level traceability and audit logs for targeted recall response

Why allergen risk is rising for UK food businesses in 2025 

FSA incidents and allergy alerts 

The FSA's 2025/26 annual report recorded 2,073 food and feed safety incidents across England, Wales and Northern Ireland, a 14% year-on-year rise, with allergens the second most common hazard category after pathogens.

Allergy alerts issued by the FSA and Food Standards Scotland rose from 64 in 2023 to 101 in 2024, driven largely by a single mustard and peanut cross-contamination incident that triggered 3 primary alerts and 31 follow-up alerts across 59 brands and 307 products, including Iceland, Domino's, Waitrose, Papa John's, Spar and Harvester. 

Allergen-related product recalls in 2025 

UK food businesses recalled 141 products in 2025, a 23% rise on 2024's 115. Allergens caused 23% of all recalls, the single largest cause, ahead of Listeria at 10%. The FSA estimates that around 1 in 100 catering menus carries an undeclared allergen risk at any time, and Aldi and Lidl together accounted for 13% of 2025's recalled products, mainly due to labelling failures and contamination.

Across all three data sets, the pattern is the same: allergen failures trace back to gaps in ingredient-level visibility rather than novel hazards, which is exactly the gap allergen management software is designed to close. 

UK food allergy statistics and why they matter 

Around 2 million people in the UK have a diagnosed food allergy, and it affects 5% to 8% of UK children, one of the highest rates in the developed world.

An FSA-funded Imperial College London study of NHS data from 1998 to 2018 found hospital admissions for food-induced anaphylaxis rose from 1.23 to 4.02 per 100,000 people per year, while the case fatality rate more than halved, from 0.7% to under 0.3%. At least 46% of the 152 deaths recorded were triggered by peanut or tree nuts, and cows' milk was the most common cause of fatal anaphylaxis in children under 16.

Around 80% of childhood anaphylactic reactions happen at school or when eating food prepared outside the home, which is why understanding food allergens and why they're a risk to your business matters as much to food businesses as it does to families. 

Key features of allergen management software 

• Ingredient-level traceability: tracking allergen-containing ingredients from supplier intake to finished product, including substitutions. 
• Supplier audit trails: verifying supplier allergen declarations, with risk scoring for high-risk suppliers or ingredients. 
• Verbal and written communication logging: recording both spoken and written allergen information in catering and front-of-house settings. 
• Training and competency records: evidencing that staff have completed role-relevant allergen training. 
• Automated change alerts: flagging recipe or supplier changes that could introduce an undeclared allergen before it reaches a customer. 

How to choose allergen management software 

Not all food safety software treats allergen management as a first-class workflow. When evaluating allergen traceability software, check whether it can: 

• Map directly to Natasha's Law and FSA guidance, so labelling and communication requirements are met by design, not adapted from generic templates 
• Maintain a single audit trail across multiple sites, so compliance evidence comes from one place instead of being reconciled manually across spreadsheets 
• Capture both verbal and written allergen communications, so front-of-house teams have provable evidence of what customers were told, not just what was served 
• Flag ingredient or recipe changes automatically, so an allergen risk is caught before it reaches production or a menu, not after 
• Support fast, batch-level traceability, so recalls and allergy alerts are resolved in hours rather than days 

Ideagen Food & Beverage is built around HACCP, supplier management and allergen workflows aligned to GFSI, BRCGS and ISO 22000, rather than adapted from a generic quality management system, with multi-site dashboards giving a single view of compliance posture and corrective actions. 

Staying ahead of food allergen compliance in the UK 

The direction of UK allergen regulation is clear even where legislation lags behind it. FSA data on incidents, alerts and recalls shows that allergen failures are rarely caused by unknown hazards, but by gaps in ingredient-level visibility that spreadsheets and paper trails struggle to close.

Platforms such as Ideagen Food & Beverage, built around HACCP, supplier management and allergen workflows aligned to GFSI, BRCGS and ISO 22000, exist specifically to close that gap. UK food businesses that treat allergen management as a core part of their compliance program, rather than a reaction to the next headline recall, are the ones best placed to meet whatever comes next, whether that is stricter guidance, formal legislation or simply a more demanding customer.
