Salmonella poisoning, also known as food poisoning or salmonellosis, is an infection caused by bacteria called Salmonella. It can be contracted through the consumption of contaminated foods or water, particularly undercooked poultry and eggs. Symptoms include sudden onset of diarrhea, fever, nausea, vomiting, and abdominal pain. People infected may experience mild symptoms for a short period, but severe cases can result in dehydration and hospitalization.
