Salmonella infection is usually caused by eating raw or undercooked meat, poultry, and eggs or egg products or by drinking unpasteurized milk. The incubation period — the time between exposure and illness — can be 6 hours to 6 days. Often, people who have salmonella infection think they have the stomach flu.
Possible signs and symptoms of salmonella infection include:
•Diarrhea
•Stomach (abdominal) cramps
•Fever
•Nausea
Most people don't need to seek medical attention for salmonella infection because it clears up on its own within a few days.
However, if the affected person is an infant, young child, older adult or someone with a weakened immune system, call a health care provider if illness:
•Lasts more than a few days
•Is associated with high fever or bloody stools
•Appears to be causing dehydration, with signs such as such as urinating less than usual, dark-colored urine and having a dry mouth and tongue
