Quick answer
After an allergen incident, protect people, stop further exposure, preserve relevant evidence and escalate promptly to the responsible manager and appropriate authority. Establish which food and customers may be affected before investigating the cause. Do not wait for the root-cause investigation to finish before taking necessary containment or reporting action.
Protect people and contain the food concern
If a person is unwell, activate the setting’s emergency arrangements immediately; the medical response belongs to trained roles and emergency services. This guide addresses the business investigation and follow-up, not treatment. In parallel, stop the relevant preparation, service or sale where needed and prevent further affected food being supplied.
FSA incident guidance for England, Northern Ireland and Wales explains withdrawal, recall and competent-authority notification. Food Standards Scotland’s incident guidance gives Scottish responsibilities. Follow the applicable reporting route promptly; do not wait for certainty about the final cause.
Preserve evidence without delaying action
- Identify the meal or product, date, time, batch and ingredient versions where available.
- Retain relevant food, packaging, labels, specifications, order information and preparation records appropriately.
- Record what was reported, what staff observed and which actions were taken, keeping fact and assumption separate.
- Secure relevant digital and physical records against deletion or routine overwriting.
Coordinate handling or sampling with the relevant authority and competent advisers. Preserve evidence without putting staff or customers at further risk. Collect only relevant personal information and keep access appropriate.
Determine the extent of the affected food
Trace the implicated ingredients, recipes, equipment, labels and service periods. Check whether the concern affects other dishes or batches, outlets, online information or business customers. A single complaint may reveal a wider issue; equally, the extent needs evidence rather than assumptions.
Illustrative example: the investigation identifies a wrong label template used during one production run. Determine which products received that label and where they went. Replacing the template does not address food already supplied. Coordinate necessary withdrawal, recall and consumer communication with the authority.
Investigate how the control failed
| Area | Example evidence question |
|---|---|
| Ingredient evidence | Was the actual ingredient different from the approved specification? |
| Information control | Did the recipe, label, matrix and menu describe the same version? |
| Preparation | Was there an uncontrolled transfer route or unsuitable cleaning arrangement? |
| Order and service | Did the request reach preparation and the correct item reach the customer? |
| Management | Were owners, cover, equipment and escalation workable? |
The FSA guidance includes root-cause analysis. “Staff error” describes an event, not necessarily the underlying reason. Examine unclear instructions, conflicting information, workload and missing checks before selecting the action.
Verify recovery and capture learning
Keep a decision log, action owners and evidence supporting any restart or release. Use competent assessment and authority advice; a negative test or absence of further complaints alone cannot establish that every affected product is suitable.
After immediate controls, verify that changes work in practice. Update related procedures and instruction, and review similar products or sites. Support staff to report near misses. Closing an investigation should leave an understandable record of the scope, decisions, causes, actions and effectiveness.
Next steps
- Activate emergency arrangements for any person at risk and contain further supply.
- Escalate and report through the relevant national and local authority routes.
- Preserve evidence and establish the extent of affected food.
- Investigate causes, verify corrective action and document the recovery decision.
