What should you know about KFC food poisoning?

Food poisoning can cause diarrhoea, nausea, vomiting, abdominal cramps, and fever. Symptoms may begin after a delay, and the timing alone cannot prove which food caused illness. Similar symptoms can come from a stomach virus or another infection. The main early concern is fluid and salt loss, particularly when vomiting or diarrhoea makes drinking difficult.

Blood in stool, severe abdominal pain, marked weakness, or reduced urination can signal a need for prompt assessment. Children, older adults, pregnant people, and people with long-term illnesses may become dehydrated more quickly.

Take frequent small sips of water or an oral rehydration drink; an [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) page explains the purpose of balanced fluids. Rest, eat light foods when able, and avoid alcohol. Wash hands carefully and avoid preparing food for others while unwell. Note when symptoms started, how often you vomit or pass stool, your temperature, and what you have managed to drink.

Do not use leftover antibiotics or medicines intended for someone else. A clinician can decide whether testing or treatment is appropriate.

Seek urgent care for fainting, confusion, severe dehydration, blood in vomit or stool, severe or localised abdominal pain, breathing difficulty, or inability to keep fluids down. Contact a clinician promptly for persistent vomiting, worsening diarrhoea, fever with significant illness, or symptoms in a vulnerable person. [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/) may be considered when drinking is not enough.

Could this be food poisoning or another infection? How much should I drink, and should I use oral rehydration fluids? Which symptoms mean I should attend urgent care? Do I need testing, sick leave advice, or treatment for vomiting or diarrhoea?
