Types of food poisoning

Contamination can occur during growing, preparation, storage or serving. Some germs multiply in the gut, while others release toxins that irritate the digestive tract. Common symptoms include Nausea, Vomiting, Diarrhoea, abdominal cramps and Fever, but the combination and timing can differ. Several people becoming ill after sharing a meal can be a useful clue, though it does not identify the organism.

Food poisoning is not the only explanation for stomach symptoms. A clinician may consider medication effects, an infection unrelated to food, or another digestive condition. Testing is more likely to help when illness is severe, prolonged, associated with blood, or affects a vulnerable person.

Take frequent small sips of water or Oral Rehydration Therapy, especially after loose stools or vomiting. Rest, eat light foods when able, and avoid preparing food for others while unwell. Do not use leftover antibiotics or medicines to stop diarrhoea without advice; the right choice depends on the cause and your symptoms. A clinician may recommend IV Fluid Therapy when dehydration cannot be corrected by drinking.

Arrange urgent assessment for blood in stool or vomit, severe or worsening Abdominal Pain, confusion, fainting, very little urine, inability to keep fluids down, or a persistent high Fever. Seek advice sooner for infants, older adults, pregnancy, or people with significant long-term illness, because dehydration can develop quickly.

Could this be food poisoning or another illness? Do I need a stool test? Which fluids and foods are suitable, and what signs mean I should return for care?
