What is food poisoning?
Food poisoning occurs when you eat food that is contaminated with harmful bacteria, viruses, parasites or toxins. This contamination can happen at any stage of food production: Either processing or preparation. When you consume contaminated food, these harmful organisms or substances enter your body and can cause illness.
Symptoms of food poisoning can vary depending on the type of contaminant and the amount ingested, but common symptoms include nausea, vomiting, stomach cramps, diarrhoea, fever and weakness. These symptoms usually develop within a few hours to a few days after eating contaminated food.
Preventing food poisoning involves practising good food safety habits, such as washing your hands before handling food, cooking food thoroughly, storing food at the proper temperature, avoiding cross-contamination between raw and cooked foods and consuming perishable foods promptly.
If you suspect that you have food poisoning, it is essential to stay hydrated and rest. In severe cases or if symptoms persist, seek medical attention. Food poisoning can be especially dangerous for vulnerable populations, such as young children, elderly individuals, pregnant women and people with weakened immune systems.

Top 10 food poisoning symptoms
Food poisoning can turn a delicious meal into a gut-wrenching experience. Here is a rundown of the top 10 unwelcome guests that might show up after consuming contaminated food:
- Bellyache: Abdominal cramps or stomach pain are common symptoms of food poisoning and can range from mild discomfort to severe cramping. Cramps occur as the body attempts to expel contaminated food and toxins through vomiting or diarrhoea. The pain may be localised or diffuse and can vary in intensity depending on the severity of the infection and individual tolerance levels.
- Nausea: Nausea is an unpleasant sensation of unease or discomfort in the stomach that often precedes vomiting. It can range from mild queasiness to intense discomfort, making it difficult to eat or drink. Nausea is a common early symptom of food poisoning and is caused by the body’s response to harmful bacteria, viruses, parasites or toxins present in contaminated food.
- Vomiting: Vomiting is the forceful expulsion of stomach contents through the mouth and is a common symptom of food poisoning. It occurs when the body’s natural defence mechanisms attempt to rid the digestive system of harmful pathogens or toxins. Vomiting can be sudden and intense, often providing temporary relief from nausea but contributing to dehydration and electrolyte imbalances.
- Diarrhoea: Diarrhoea is characterised by loose, watery stools and an increased frequency of bowel movements. It is a common symptom of food poisoning caused by bacterial or viral infections that disrupt normal digestive processes. It can lead to dehydration, electrolyte imbalances and the loss of essential nutrients, requiring prompt management and fluid replacement.
- Fever: Fever is a sign of the body’s immune response to infection and inflammation caused by foodborne pathogens. It is characterised by an elevated body temperature above the normal range and may accompany other symptoms of food poisoning, such as nausea, vomiting and diarrhoea. Fever helps the body fight off infection by stimulating immune system activity and inhibiting the growth of harmful bacteria or viruses.
- Headache: Headaches are common during food poisoning and can result from dehydration, electrolyte imbalances or the body’s inflammatory response to infection. The headache may be dull or throbbing and can vary in intensity from mild discomfort to severe pain. Headaches may also be accompanied by other symptoms such as fever, muscle aches, and fatigue.
- Fatigue: Fatigue or extreme tiredness is a common symptom of food poisoning and can result from the body’s efforts to fight off infection and recover from illness. Fatigue may be accompanied by weakness, lethargy and decreased energy levels, making it difficult to perform daily activities or concentrate. Adequate rest and fluid intake are essential for managing the fatigue associated with food poisoning.
- Muscle aches: Muscle aches or myalgia can occur with certain types of food poisoning, particularly those caused by bacterial or viral infections that affect the entire body. Muscle aches may be generalised or localised and can range from mild discomfort to severe pain. They are often accompanied by other symptoms such as fever, headache, and fatigue, reflecting the body’s inflammatory response to infection.
- Dehydration: Dehydration occurs when the body loses more fluids than it takes in, leading to a lack of adequate hydration. Diarrhoea and vomiting associated with food poisoning can cause fluid loss and electrolyte imbalances, increasing the risk of dehydration. Symptoms of dehydration include increased thirst, dry mouth, dark urine, fatigue and dizziness. Severe dehydration requires prompt medical attention and fluid replacement therapy.
- Loss of appetite: Loss of appetite, or anorexia, is a common symptom of food poisoning and can result from nausea, stomach discomfort and other gastrointestinal symptoms. People with food poisoning may experience a reduced desire to eat or drink, leading to decreased food intake and nutritional deficiencies. Loss of appetite is usually temporary and resolves once symptoms improve, but adequate fluid intake is essential to prevent dehydration and support recovery.

Treatment of food poisoning
Treating food poisoning can be uncomfortable, but the good news is that it typically resolves on its own within a few days. Here are some tips to help manage symptoms and promote a speedy recovery:
Stay hydrated:
- Dehydration is a major concern with food poisoning, as vomiting and diarrhoea can quickly deplete the body’s fluids and electrolytes.
- Sip fluids constantly: Aim for small, frequent sips of water, clear broths or oral rehydration solutions like Pedialyte or electrolyte. Avoid sugary drinks, caffeine and alcohol as they can worsen diarrhoea.
- Suck on ice chips: This can help rehydrate, especially if drinking fluids is difficult due to nausea.
Ease symptoms:
- Rest: Allow your body the time it needs to recover by getting plenty of rest.
- Bland diet: Once nausea subsides, introduce bland foods like toast, crackers, bananas, rice or applesauce. These are gentle on the stomach and can help replenish electrolytes.
- Over-the-counter relief (with caution): Medications like pepto-bismol (bismuth subsalicylate) can ease nausea and diarrhoea. However, consult a doctor before using them, especially if you have certain medical conditions or are taking other medications. Loperamide (Imodium) may be helpful for diarrhoea, but avoid it if you have a fever or bloody stools.
