What to Do After Food Poisoning
Food poisoning produces substantial UK personal injury claims annually — from restaurants, takeaways, supermarkets, hotels, all-inclusive holidays, and food manufacturers. UK Food Standards Agency data indicates around 2.4 million cases annually with substantial reporting underreporting. Beyond the immediate illness, food poisoning can cause: lasting digestive issues (IBS post-infection), kidney damage (particularly E. coli O157), reactive arthritis (particularly Salmonella, Campylobacter), Guillain-Barré syndrome (rare Campylobacter complication), and substantial lost earnings. The legal framework includes the Food Safety Act 1990, Consumer Protection Act 1987 (strict liability for defective products), Consumer Rights Act 2015 (services with reasonable care and skill), and the Package Travel Regulations 2018 for holiday-related illness. Acting promptly to preserve evidence — particularly stool samples for laboratory testing — substantially affects claim success. Specific bacterial identification provides strong evidence.

This guide walks through exactly what to do after UK food poisoning — immediately, in the following days, and how to start a compensation claim.
Immediate Steps
Step 1: Hydration
Critical priority:
- Drink water in small frequent sips
- Oral rehydration solution (Dioralyte)
- Avoid alcohol and caffeine
- Monitor for severe dehydration
Step 2: Get Medical Attention
When to seek help:

- A&E for high fever, severe abdominal pain
- GP within 24-48 hours for moderate symptoms
- NHS 111 for guidance
Step 3: Document Symptoms
- Detailed diary of symptoms
- Time of onset relative to suspected food
- Specific symptoms (vomiting, diarrhoea, fever, cramping)
- Severity over time
- Photograph if visible signs
Critical: Stool Sample
Why Critical
Best evidence for claims:

- Strongest evidence of food poisoning
- Specific pathogen identification
- Substantial UK case law
How to Request
Process:
- Specifically request stool sample test from GP/A&E

- Insist if symptoms warrant
What’s Tested For
- Salmonella
- Campylobacter
- E. coli (including O157)
- Listeria
- Shigella
- Norovirus (sometimes)

Identify the Source
What You Ate
Document carefully:
- All food and drink consumed in 72 hours before symptoms
- Specific restaurants, takeaways, supermarkets

Common Mistakes to Avoid
At the Time
- Not getting medical attention for moderate symptoms
- Not requesting stool sample test

Afterwards
- Delaying specialist solicitor engagement

No Win No Fee Food Poisoning Claims
Food poisoning compensation claims run on no win no fee Conditional Fee Agreements. The success fee — capped under LASPO 2012 at 25 per cent of general damages and past losses (future losses excluded) — is deducted from compensation. After-the-Event insurance protects against adverse costs. The ATE premium is normally payable only if you win, deducted from your compensation — it is no longer recoverable from the defendant — and your solicitor must explain how the premium and disbursements are treated before you sign (see how ATE insurance works). See our how no win no fee works guide.
Common Questions After Food Poisoning
How do I prove the specific food caused my illness?
Combination of evidence:
- Stool sample identifying specific bacteria
- Timing of consumption vs symptom onset (each pathogen has specific incubation period)
- Other people with same symptoms (cluster evidence)
- Environmental Health investigation findings
- Specific food manufacturer issues (recalls, batch problems)
Specialist solicitors regularly succeed with causation arguments. Single-person cases without specific evidence can be challenging but successful. Multi-person clusters or specific pathogen identification substantially strengthen cases.
I didn’t request a stool sample. Can I still claim?
Often yes, but harder. Without specific laboratory identification:
- Causation typically more disputed
- Specific timing and circumstances matter more
- Other evidence (multiple people affected, food recalls, environmental health findings) helps
- Specific symptom presentation can identify pathogen type
Specialist solicitors regularly succeed without stool samples but evidence preparation is more substantial. Don’t let lack of sample prevent specialist consultation.
I had food poisoning at a hotel on holiday. Can I claim?
Often yes. UK package holiday food poisoning is a substantial claim category:
- Tour operator liable under Package Travel Regulations 2018
- UK courts have jurisdiction
- Standard English law applies
- Multiple-affected guests strengthen substantially
All-inclusive hotels are common settings — buffet hygiene failures, temperature control issues, cross-contamination. Substantial UK case law. Specialist solicitors handle holiday food poisoning as standard. See our holiday illness claims guide.
I have lasting digestive problems after food poisoning. Can I claim more?
Yes, substantially. Post-infectious IBS:
- Affects 10-20% of food poisoning sufferers
- Specific medical recognition
- Substantial additional component to compensation
- Can be lifetime condition
Compensation can be substantial — IBS substantially affects quality of life. Specialist gastroenterology evidence helps establish causation. Settlements often substantial where post-infectious IBS established. Specific UK case law supports these claims.
My child got food poisoning from supermarket food. What can we claim?
Substantial claim potential. Children’s food poisoning cases:
- Consumer Protection Act 1987 (strict liability) if manufactured food
- Major UK supermarkets all carry substantial insurance
- Children’s claims typically higher than equivalent adult
- Particular concern about kidney damage (HUS) from E. coli
Children’s claims have time running from 18th birthday. Court approval for child settlements. Specialist solicitors handle these as standard. See our claiming for a child guide.
When should I engage a solicitor?
Within days. Free initial consultation recommended. Specialist solicitors:
- Help arrange stool sample testing if not done
- Send preservation letters to defendants
- Handle Environmental Health investigation coordination
- Arrange specialist medical examination
- Calculate full compensation including future complications
No commitment from initial consultation. No win no fee available. Specialist firms with food poisoning case experience particularly valuable. See our how no win no fee works guide.
