What Happens If a Customer Gets Food Poisoning From Your Restaurant?
Food poisoning affects around 2.4 million people in the UK each year, according to the Food Standards Agency.
Food poisoning affects around 2.4 million people in the UK each year, according to the Food Standards Agency. When a customer falls ill after eating at your premises, the consequences extend far beyond a single complaint. Under the Food Safety Act 1990 and the Food Hygiene (England) Regulations 2006, food business operators have a legal duty to ensure food is safe to eat. A confirmed case of food poisoning can trigger an Environmental Health Officer investigation, potential prosecution, and civil claims for compensation. The financial and reputational damage can be severe, particularly if poor hygiene practices are identified during the investigation. For small and medium hospitality businesses, a single incident can threaten the viability of the entire operation.
What happens next
Environmental Health Investigation
Your local authority will likely send an Environmental Health Officer to conduct an unannounced inspection. They will examine your food safety management system, temperature records, cleaning schedules, and staff training documentation. Any gaps in your records will be flagged as potential contributing factors.
Potential Closure Notice
If the EHO identifies an imminent risk to health, they can issue a Hygiene Emergency Prohibition Notice under Section 12 of the Food Safety Act 1990. This forces immediate closure of all or part of your premises until a magistrates court confirms or lifts the order.
Negative Publicity and Reviews
Customers who experience food poisoning frequently post about it on Google, TripAdvisor, and social media. A single food poisoning complaint can generate significant negative coverage that deters potential customers for months. Recovery of online reputation takes considerable time and effort.
Staff Morale and Retention Impact
A food poisoning incident creates stress for your team, especially if they are interviewed during the investigation. Staff may feel personally responsible, and the uncertainty around potential enforcement action can lead to increased turnover at a time when you need stability.
The cost to your business
Fines
Prosecutions under the Food Safety Act 1990 can result in unlimited fines in the Crown Court. Magistrates court fines typically range from £5,000 to £20,000 per offence, but serious cases are referred upward.
Compensation Claims
Victims of food poisoning can pursue civil claims. Minor cases typically settle for £1,000 to £5,000, but hospitalisation or long-term complications (such as reactive arthritis from Salmonella) can push claims well above £50,000.
Lost Revenue
Temporary closure, reduced footfall from negative reviews, and cancelled bookings can cost tens of thousands in lost revenue. Businesses that rely on seasonal trade are particularly vulnerable.
Remediation Costs
Deep cleaning, equipment replacement, updated HACCP plans, additional staff training, and consultant fees to bring the business back into compliance all carry significant costs.
Your legal exposure
Criminal Prosecution
Food Safety Act 1990, Sections 7-8
Selling food that fails to comply with food safety requirements is a criminal offence. Section 7 covers rendering food injurious to health, while Section 8 covers selling food not of the nature, substance, or quality demanded. Both carry unlimited fines and up to two years imprisonment.
Breach of Hygiene Regulations
Food Hygiene (England) Regulations 2006, Regulation 4
Food business operators must ensure that all stages of production, processing, and distribution under their control satisfy the relevant hygiene requirements of EC Regulation 852/2004. Failure to maintain adequate food safety management procedures is a standalone offence.
Civil Liability for Damages
Consumer Protection Act 1987
Customers can bring civil claims for personal injury caused by unsafe food products without needing to prove negligence. The burden of proof sits with the business to demonstrate the food was safe when it left their control.
UK food poisoning prosecutions remain common
Local authorities in the UK prosecute hundreds of food businesses each year for food safety offences. The FSA reports that Campylobacter alone causes an estimated 300,000 cases annually, with contaminated chicken being the primary source. Businesses with poor HACCP documentation and inadequate temperature monitoring are consistently the most likely to face enforcement action following food poisoning complaints.
How to prevent this
Implement a documented HACCP plan
A Hazard Analysis and Critical Control Points plan is legally required under EC Regulation 852/2004. It must identify hazards, set critical limits, and define monitoring procedures for every stage of food preparation.
Record temperatures consistently
Log fridge, freezer, cooking, and hot-holding temperatures at scheduled intervals. Ensure probes are calibrated and staff know the required ranges for different food types.
Train all staff in food hygiene
Every food handler must receive appropriate food hygiene training. Level 2 Food Safety in Catering is the standard baseline, and refresher training should be delivered at least every three years.
Maintain cleaning schedules with records
Documented cleaning schedules covering all equipment, surfaces, and storage areas provide evidence of compliance during inspections. Include the method, frequency, chemicals used, and responsible person.
Monitor supplier due diligence
Keep records of supplier food safety certifications, delivery temperature checks, and any product recalls. Traceability documentation must allow you to identify the source of any ingredient.
If it has already happened
Cooperate fully with the EHO investigation
Provide all requested documentation promptly and honestly. Being transparent and cooperative is taken into account during enforcement decisions and can make the difference between a warning and prosecution.
Conduct an internal root cause analysis
Identify exactly what went wrong, whether it was a process failure, training gap, equipment issue, or supplier problem. Document your findings and the corrective actions you have taken.
Implement corrective actions immediately
Address the identified issues before the EHO returns for a follow-up visit. This might include retraining staff, replacing equipment, updating your HACCP plan, or changing suppliers.
Communicate transparently with the affected customer
Acknowledge the complaint, express genuine concern, and explain the steps you are taking to prevent recurrence. Avoid admitting liability in writing, but do not be dismissive or defensive.
Request a re-rating if your FHRS score drops
Under the Brand New Ratings scheme, you can request a re-inspection once you have made improvements. Demonstrate that your corrective actions are embedded, not just temporary fixes.

Why this matters
Common questions
Can a customer sue my restaurant for food poisoning?
Yes. Customers can bring a civil claim for personal injury and associated losses. Under the Consumer Protection Act 1987, they do not need to prove negligence if they can show the food was defective. Claims typically settle between £1,000 and £50,000 depending on the severity and duration of illness.
Will my food hygiene rating drop after a food poisoning complaint?
Not automatically, but the investigation will likely trigger an inspection. If the EHO finds failings in your food safety management system, your FHRS score can be reduced. Scores are based on hygienic food handling, structural compliance, and confidence in management.
How long does a food poisoning investigation take?
Investigations typically take between 2 and 12 weeks, depending on the complexity. The EHO will visit your premises, take samples, review records, and interview staff. If prosecution is pursued, the process can extend to several months.
Do I need to report food poisoning cases to anyone?
Food poisoning is a notifiable disease under the Health Protection (Notification) Regulations 2010. Doctors must report confirmed cases to Public Health England. If you become aware of multiple linked cases, you should contact your local Environmental Health team proactively.
