Food poisoning from salad symptoms

Raw leafy vegetables and chopped ingredients are not made safer by cooking after they are served. Germs can reach salad through contaminated water, soil, hands, utensils, or contact with raw foods. Food poisoning from salad commonly presents with loose stools, abdominal pain, nausea, vomiting, or fever. The exact cause cannot usually be identified from symptoms alone, and several people who ate the same dish becoming ill is useful information for a clinician.

Fluid loss matters more than the appearance of the salad. Thirst, dry lips, reduced urination, dark urine, weakness, or light-headedness suggest that you need closer attention to hydration.

Sip water often, and consider [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) if diarrhoea or vomiting is substantial. Eat small, plain meals when appetite returns. Avoid preparing food for others, wash hands with soap, and clean shared bathroom surfaces. Keep a note of when symptoms began and what you ate, especially if others are unwell.

Do not use leftover salad if it has been warm or its handling is unclear. A clinician can decide whether treatment or testing is needed; dehydration that cannot be corrected by drinking may require [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/).

Get urgent medical help for blood in stool or vomit, severe abdominal pain, fainting, confusion, inability to drink, or very little urine. Arrange prompt medical advice if fever is persistent, symptoms are worsening, or illness affects a young child, older adult, pregnant person, or someone with reduced immunity. Emergency help is appropriate for collapse or severe breathing difficulty.

Ask whether this could be [Food Poisoning](/conditions/food-poisoning/), how to judge hydration, whether you need testing, and when it is safe to return to work or prepare meals.
