What are the most common food sources that can harbor salmonella bacteria?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Salmonella is a type of bacteria that causes foodborne illness, most often found in raw chicken, undercooked eggs, and contaminated fresh produce. When these foods aren't cooked thoroughly or handled with clean hands and surfaces, salmonella can spread and lead to symptoms like diarrhea, stomach cramps, fever, and vomiting within 6 hours to 6 days of exposure.

If you suspect you've been exposed to salmonella or are experiencing symptoms, acting quickly matters—dehydration and complications can escalate, especially for children, older adults, and those with weakened immune systems. A free, instant, online symptom check can help you understand what's driving your symptoms and guide your next steps in minutes, so you know whether home care is enough or if it's time to see a doctor.
