Yes, you can sue for food poisoning in the UK, and you don’t necessarily have to prove the business was careless. The Consumer Protection Act 1987 imposes strict liability on producers and suppliers of defective products, food included, so contaminated food that made you ill can ground a claim on its own facts.1Legislation.gov.uk. Consumer Protection Act 1987 – Part I You have three years from the date you fell ill, or from the date you first linked the illness to the food, to bring the claim.2Legislation.gov.uk. Limitation Act 1980 – Section 11 Everything else — who to sue, what evidence to gather, what the case is worth — flows from those two points.
Who You Can Sue
The right defendant depends on where the contamination entered the food. Restaurants, cafes, and takeaways owe a duty to prepare and serve food safely, so if you fell ill after eating out, that business is usually the first target. Supermarkets and other retailers can be liable too, particularly for own-brand products or items sold past their use-by dates or in compromised packaging. Manufacturers carry responsibility where the problem began at production or packaging, and this is where the strict liability route is most useful: you don’t have to reconstruct exactly what went wrong on the factory floor, only that the product was defective by the time it reached you. Caterers for weddings, corporate events, and similar functions sit under the same obligations.
You may not know at the outset which link in the chain failed. A local authority investigation and your solicitor’s enquiries can identify the correct defendant, and if responsibility is shared, you can claim against more than one party.
How Long You Have to Bring a Claim
Three years is the limit under the Limitation Act 1980. The clock starts on the date you became ill or the date you first knew (or reasonably should have known) that your illness was linked to contaminated food, whichever is later.2Legislation.gov.uk. Limitation Act 1980 – Section 11 That later trigger matters because symptoms sometimes take days to appear and pinpointing the meal that caused them can take longer.
Three years sounds generous, but delay damages the case. Food samples get thrown out, kitchen records are overwritten, and witnesses forget. If a local authority investigation is going to help you, it needs to run while the evidence still exists. Starting within weeks, not months, puts you in the strongest position.
Proving the Food Made You Ill
Causation is where food poisoning claims are won or lost. You need a clear line between what you ate and what happened to you. The following build that line:
- Medical records. See your GP or attend A&E as soon as symptoms appear. Ask for blood or stool testing — laboratory identification of the specific pathogen is far more persuasive than a general note of “gastroenteritis.” Ask the doctor to record what you ate and when.
- A report to the local authority where the food business is located. The council’s food safety team will investigate, and any hygiene breaches or parallel complaints they find will strengthen your claim.3Food Standards Agency. Report a Food Safety or Hygiene Issue
- Physical evidence. Keep leftover food, original packaging, and receipts. Refrigerate or freeze the food. Packaging often carries batch numbers that trace the product to a production run.
- A food diary covering the 72 hours before symptoms began, with dates, times, and locations. This helps rule out alternative sources.
- Contact details for anyone else who shared the meal and became ill. Multiple people falling sick from the same source is powerful circumstantial evidence.
The single most valuable step is the stool sample. Without laboratory confirmation of the pathogen, the case rests on inference, and defendants know that is weaker ground for negotiation.
What Your Claim Could Be Worth
Compensation splits in two. General damages cover pain, suffering, and the effect on your daily life. Special damages reimburse the financial losses you can document.
General Damages
Courts apply the Judicial College Guidelines, and the bracket depends on severity and duration:
- Mild cases lasting a few days to a few weeks, with cramps, diarrhoea, and some short-term disability: roughly £1,110 to £4,820.
- Moderate cases needing hospital admission, with fatigue, altered bowel function, and cramps over several days: roughly £4,820 to £11,640.
- Serious cases where acute symptoms fade over two to four weeks but leave lingering discomfort for a couple of years: roughly £11,640 to £23,430.
- Severe toxicosis with acute pain, diarrhoea, and vomiting requiring extended hospital care: roughly £46,900 to £64,070.
Where the illness leaves lasting bowel damage or other permanent complications, figures climb well above these brackets.
Special Damages
Special damages cover every out-of-pocket cost the illness caused: prescription charges and over-the-counter medication, lost earnings for time already off work and any projected future losses, travel to medical appointments, and care or assistance you needed during recovery. Keep receipts for all of it. Unlike general damages, each item of special damages needs documentary proof.
When Food Poisoning Causes Lasting Harm
Some infections trigger chronic conditions that change your health permanently. Reactive arthritis, an inflammatory joint condition, follows a small but consistent share of Salmonella, Campylobacter, Shigella, and Yersinia infections, and people carrying the HLA-B27 gene face a much higher risk. Haemolytic uraemic syndrome — kidney failure, blood clotting problems, and anaemia — can develop after E. coli O157 infection, and some patients need dialysis or suffer permanent kidney damage.4CDC. Chronic Sequelae of Foodborne Disease Research also links certain enteric infections to inflammatory bowel disease, though that causal picture is less settled.
If your food poisoning led to any of these outcomes, the claim is worth considerably more than the standard brackets for digestive illness suggest, and a medical expert report tying the chronic condition back to the original infection becomes essential.
How the Claim Actually Moves
Most food poisoning claims settle without a hearing, but the route follows a set sequence.
The Pre-Action Protocol
Before issuing proceedings, you follow the Pre-Action Protocol for Personal Injury Claims, which is designed to let parties settle before litigation. Your solicitor sends a Letter of Claim setting out what happened, the nature and impact of the illness, and an outline of your losses. The defendant has 21 calendar days to acknowledge. If they don’t, you can issue proceedings straight away.5Justice UK. Pre-Action Protocol for Personal Injury Claims
After acknowledgement, the defendant has up to three months to investigate and confirm whether liability is admitted.5Justice UK. Pre-Action Protocol for Personal Injury Claims Documents and expert reports are exchanged, and most claims settle here through negotiation. If liability is denied or the offer is too low, your solicitor issues proceedings.
Which Court Track Applies
Claims valued under £10,000 go through the small claims track, where the process is less formal and costs recovery is limited. Higher-value claims go to the fast track or, for complex cases, the multi-track. The total value, including general and special damages together, decides the track.
Paying for a Solicitor
Cost is what puts most people off, but personal injury solicitors generally work on a “no win, no fee” basis. Under a conditional fee agreement, the solicitor is paid only if the claim succeeds, and if it fails you typically owe them nothing.6SRA. No Win, No Fee Agreements – A Guide to Navigating Them
There is one exposure to understand. If you lose, you could be liable for the other side’s costs. Solicitors normally arrange “after the event” insurance at the outset to cover that risk, and the policy pays the defendant’s costs if the claim fails.6SRA. No Win, No Fee Agreements – A Guide to Navigating Them Ask about the insurance before signing. If you win, the solicitor takes a success fee out of your compensation, and that percentage should be agreed in writing before any work starts.
