What should you know about bacteria cause food poisoning?

Different bacteria and toxins produce different patterns. Abdominal cramps, diarrhoea, nausea, vomiting, and fever may appear after eating contaminated food, sometimes after a delay. Illness often settles with supportive care, but fluid and salt loss can become dangerous, especially for young children, older adults, pregnant people, and anyone with another medical condition. Blood in stool, persistent symptoms, or severe pain needs professional assessment because other illnesses can look similar.

Take frequent small sips of water or Oral Rehydration Therapy solution. Continue light meals when able, and avoid preparing food for other people while diarrhoea or vomiting continues. Wash hands with soap, clean bathroom surfaces, and refrigerate food safely. Do not start leftover antibiotics or use anti-diarrhoeal medicine without advice. A clinician may recommend IV Fluid Therapy when vomiting prevents drinking or dehydration is substantial.

Get urgent help for fainting, confusion, very little urine, inability to keep fluids down, severe or localised abdominal pain, blood in vomit or stool, or breathing difficulty. Contact a clinician for fever that persists, diarrhoea that is not easing, or symptoms in a vulnerable person. Food Poisoning after a shared meal may warrant advice about other exposed people.

Ask whether a stool test is appropriate, how much fluid to take, which foods and medicines to avoid, and when work, school, or food handling can safely resume.
