- Nausea and vomiting
- Abdominal pain
- Diarrhea
- Fever or chills

- Salmonella: 4–7 days
- E. coli O157: 5–10 days
- Norovirus: 1–3 days
If symptoms persist for over a week, or if you experience blood in stool, high fever, or severe dehydration, seek medical attention immediately.
Recovery Period
Recovery time also varies depending on the causative agent and an individual’s health. Generally, recovery occurs within 1–2 days after symptoms subside. Severe dehydration may prolong recovery, so adequate hydration and rest are essential.
