Allergen Incident Response: What to Do When Things Go Wrong

Allergen Incident Response: What to Do When Things Go Wrong

No matter how strong your allergen management system is, you need a plan for when things go wrong. An allergic reaction in your premises is a medical emergency that requires immediate, confident action. The response in the first few minutes can be the difference between a frightening experience and a fatal outcome. Beyond the immediate medical response, you also need to manage the scene, preserve evidence, report the incident, investigate the cause, and take corrective action to prevent it from happening again. This article provides a step-by-step incident response plan that every food business should have in place and every team member should know.

Key takeaways

Call 999 immediately if a customer shows signs of allergic reaction. Do not wait for symptoms to worsen
Ask whether the customer carries an adrenaline auto-injector and assist if trained to do so
Preserve all food, packaging, and records from the incident for investigation
Report to your local authority, HSE (if applicable), and insurer as soon as possible
Investigate the root cause, implement corrective actions, and update your allergen risk assessment

Immediate Response: The First Five Minutes

If a customer reports symptoms of an allergic reaction (itching, swelling, difficulty breathing, vomiting, dizziness, or collapse), act immediately. Do not wait to see if symptoms improve. Call 999 and request an ambulance. Tell the operator that a customer is having a suspected allergic reaction and mention anaphylaxis if symptoms are severe (breathing difficulty, throat swelling, loss of consciousness). Ask the customer if they carry an adrenaline auto-injector (EpiPen, Jext, or Emerade). If they do and they are unable to self-administer, a trained first aider can assist them in using it. Do not attempt to administer one without training. If the customer is conscious, help them into a comfortable position: sitting upright if they are having difficulty breathing, or lying down with legs elevated if they feel faint. Do not force them to eat or drink anything. Stay with the customer until emergency services arrive. Assign a team member to meet the ambulance and direct paramedics to the customer.

Preserving Evidence and Information

While waiting for emergency services, gather information that will be needed for the investigation. Ask the customer (or their companion) what they ate, what allergen they have, and when symptoms started. Preserve any remaining food from the customer's meal. Do not clear the table or discard any food or packaging until it has been documented. If possible, set aside a sample of the dish the customer consumed, including any sauces, garnishes, or accompaniments. Photograph the plate and any labels or packaging. Note the time of the incident, who was involved in taking the order and preparing the food, and any relevant details about the shift (menu changes, substitute ingredients, staff on duty). Identify the batch of any ingredients used and check your allergen records for that dish. This information will be needed by the customer, the hospital, your local authority, your insurer, and potentially the police.

Reporting Obligations and Investigation

You must report the incident to your local authority Environmental Health department. They will want to know what happened, what food was involved, and what allergen controls were in place. Under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations), you may also need to report to the Health and Safety Executive if the customer is taken to hospital. Contact your insurer as soon as possible and follow their incident reporting procedure. Conduct an internal investigation while the details are fresh. Review the order process: was the allergen disclosed? Was it communicated to the kitchen? Was the allergen matrix checked? Was the dish prepared correctly? Was there a cross-contact opportunity? Identify the root cause (not just the immediate cause) and document your findings. Interview the staff involved without assigning blame at this stage. Focus on understanding what happened and why.

Corrective Action and Prevention

The investigation findings should lead to specific corrective actions. If the failure was a communication breakdown, strengthen your order-to-kitchen communication protocol. If it was a cross-contact issue, review and upgrade your separation or cleaning controls. If it was a labelling error, review your label management process. If it was a training gap, schedule immediate retraining. Implement corrective actions promptly and document what was changed, when, and by whom. Review your allergen risk assessment in light of the incident and update it to reflect the additional controls. Share the lessons learned (anonymised if appropriate) with your team. An incident that leads to genuine improvement is less likely to recur than one that is swept under the carpet. Consider whether the incident reveals a systemic weakness rather than an isolated error. If one dish had incorrect allergen information, check all dishes. If one team member lacked knowledge, test the whole team.

What to do next

Create a written allergen incident response plan

Write a step-by-step plan covering the immediate medical response, evidence preservation, reporting contacts, and investigation process. Display it in the kitchen and train all staff on it.

Train staff in first aid for allergic reactions

Include allergic reaction response in your first aid training. Ensure at least one trained first aider is on every shift who knows how to assist with an adrenaline auto-injector.

Prepare an incident documentation kit

Assemble a kit containing incident report forms, evidence bags, a camera (or designate a phone), and contact details for your local authority, HSE, and insurer. Store it in an accessible location.

Common mistakes to avoid

Mistake
Waiting to see if symptoms improve before calling an ambulance
Instead
Anaphylaxis can escalate from mild symptoms to life-threatening within minutes. Always call 999 at the first sign of a suspected allergic reaction. It is better to call unnecessarily than to call too late.
Mistake
Clearing the table and discarding food before documenting the incident
Instead
Preserve everything until it has been photographed and samples set aside. The food, packaging, and records are critical evidence for the investigation and any subsequent legal proceedings.

Frequently asked questions

Can my staff administer an EpiPen to a customer?

A trained first aider can assist a customer in using their own auto-injector if the customer is unable to do so themselves. Staff should not administer medication that does not belong to the customer. Include auto-injector assistance in your first aid training.

Do I need to close my business after an allergen incident?

Not necessarily, but you may be advised to by the investigating officer. If the incident reveals an ongoing risk (e.g. widespread labelling errors), you may need to stop serving affected products until the issue is resolved. Follow the guidance of your local authority.

Should I admit liability to the customer?

Express genuine concern and provide all assistance possible, but do not admit liability or make statements about the cause until the investigation is complete. Your insurer will advise on communications. Focus on the customer's immediate wellbeing.

How do I support staff after a serious allergen incident?

Staff involved in a serious incident may experience stress, guilt, or anxiety. Check in with them, offer support, and consider whether they need time off or access to professional support. A blame-free investigation approach helps staff process the event constructively.
