What should you know about slow poison foods?

Food poisoning is illness caused by contaminated food or drink. The timing varies because some germs or toxins irritate the gut quickly, while others take time to multiply or trigger inflammation. Early symptoms may include nausea, abdominal cramps, diarrhoea, vomiting, or fever. More than one person who shared a meal may become unwell, but a delayed onset does not by itself prove which food was responsible. Symptoms can also come from a viral illness, medication effect, or another digestive problem.

Take frequent small sips of water or an oral rehydration drink, especially after vomiting or loose stools. Rest, eat light foods when able, and avoid alcohol and foods that worsen nausea. Wash hands with soap and water and avoid preparing food for other people while ill. Keep a note of when symptoms began, recent meals, fever, stool changes, vomiting, and fluid intake. A clinician may recommend testing or IV fluid therapy if dehydration is significant or oral fluids cannot be kept down.

Seek prompt medical advice for blood in stool or vomit, severe or localised abdominal pain, persistent vomiting, signs of dehydration, high fever, or diarrhoea that is worsening or not settling. Get urgent help for confusion, fainting, very little urine, severe weakness, or difficulty breathing. Children, older adults, pregnant people, and those with weakened immunity can become dehydrated more quickly.

Ask how much fluid to take, whether a stool test is needed, which medicines are safe for your symptoms, and when you can return to work, school, or food preparation.
