Sheltered food poisoning: what to know

Food poisoning can follow food or drink contaminated during preparation, storage, serving, or handling. A sheltered setting does not remove this possibility, particularly where food is prepared for several people or refrigeration and hand hygiene are difficult to maintain. Symptoms may include Diarrhoea, Nausea, Vomiting, Abdominal Pain, and Fever. The timing and combination vary with the organism or toxin. Symptoms alone cannot identify the cause, so tell a clinician about shared meals, affected contacts, travel, and the time symptoms began.

Take frequent small sips of water or Oral Rehydration Therapy, especially after loose stools or vomiting. Rest, eat small plain meals when able, and avoid preparing food for other people while unwell. Wash hands with soap and water, clean toilet surfaces, and avoid sharing towels. Keep the food packaging or a note of what was eaten if an investigation may be needed. If fluids cannot be kept down, a clinician may consider IV Fluid Therapy.

Seek urgent medical help for confusion, fainting, very little urine, severe weakness, blood in stool or vomit, severe abdominal pain, or breathing difficulty. Arrange prompt assessment for persistent vomiting, worsening diarrhoea, fever that concerns you, or symptoms in a baby, older adult, pregnant person, or someone with a serious long-term condition. Dehydration can develop when losses are greater than fluid intake.

Ask which fluids and foods are suitable, whether testing is needed, how long to stay away from food preparation, and which signs indicate dehydration. Describe the setting, shared foods, symptom onset, stool changes, vomiting, fever, and any affected contacts.
