There are many kinds of Salmonella bacteria, but only a few cause illnesses in people. Most of the illnesses caused by Salmonella are grouped as gastroenteritis (or sometimes incorrectly referred to as “stomach flu”).
Usually, people who get salmonellosis develop symptoms within 12-36 hours but can experience symptoms as early as 6 hours to as late as 3 days after ingestion of the bacteria.
Signs and symptoms of Salmonella infection generally last 4-7 days. Most people get better without treatment. In some cases, the diarrhea associated with a Salmonella infection can be dangerously dehydrating. In that event, see a doctor immediately.
Signs and symptoms may include:
- Abdominal pain
- Muscle pains
- Bloody stools
Typhoid fever is a more severe disease caused by Salmonella.
