Patients with Salmonellosis typically present with acute bloody or non-bloody diarrhea, abdominal pain, nausea, vomiting and fever. A detailed clinical history should include recent food ingestion, recent travel, and contact with family members and friends with similar symptoms. 
The initial evaluation of the patient should assess the severity of the disease and the need for rehydrationand include detailed history taking in order to identify the likely cause of the disease. A detailed history particularly of the 72 hours prior to the presentation is essential for diagnosis. Inquiries should be made regarding:

- Details of recent meals
- Visits to farms or zoos
- Contact with pets, rodents, reptiles
- Recent antibiotic use
- Day-care attendance
- Abdominal pain that is usually cramping in nature
