• Salmonellosis

    (Infection; Salmonella Enterica; Food Poisoning)


    Salmonellosis is an infection with bacteria called salmonella. Salmonella can grow in a variety of places, such as water, raw meat, seafood, certain pets, and eggs.


    Salmonellosis is caused by ingestion of a strain of bacteria called salmonella. After the bacteria are ingested, within 6-48 hours they will pass through the stomach to the intestine where inflammation occurs and spreads.

    Risk Factors

    Factors that increase your chance of salmonellosis include:
    • Eating raw or undercooked meat, poultry, eggs, fish, or seafood
    • Eating unpasteurized dairy products
    • Eating other contaminated foods
    • Drinking contaminated water
    • Handling reptiles, especially turtles
    • Taking antibiotics
    • A compromised immune system, such as in:
      • Elderly persons
      • Infants
      • People with HIV/AIDS
      • People with low stomach acidity, such as those who take medication that reduces stomach acid


    Symptoms occur within 12-72 hours and may include:
    • Nausea
    • Diarrhea
    • Abdominal cramps
    • Fever
    • Vomiting
    • Headaches


    You will be asked about your symptoms and medical history. A physical exam will be done. Your doctor may test your stool or blood to confirm presence of the bacteria


    Over-the-counter medications or oral rehydration solutions may be used to treat the symptoms of salmonellosis. The symptoms will usually improve on their own within 2-5 days. If symptoms are severe, talk with your doctor about the best treatment plan for you. Treatment options include the following:
    • Rehydration therapy— Oral or IV fluid replacement is needed; electrolytes may also be added to the solution.
    • Acetaminophen or ibuprofen—Over-the-counter pain relievers may be used to reduce fever or treat headaches and other pain.
    • Antibiotics—These are required only in severe cases where blood infection may occur. Antibiotic use in non-severe cases does not improve a person's outcome. It may cause the bacteria to stay longer in your system.


    To help reduce your chance of salmonellosis:
    • Frequently wash hands and surfaces.
    • Wash hands and cutting boards with hot soapy water before and after handling raw foods.
    • Wash utensils thoroughly after using them on raw meats, fish, or poultry.
    • Do not use the same cutting boards for raw meats and raw vegetables.
    • Do not drink unpasteurized milk.
    • Drink bottled or purified water when traveling.
    • Cook all foods to appropriate temperatures.
    • Place foods in the refrigerator promptly.
    • Wash hands after handling reptiles.
    • Certain medications, like those to reduce stomach acid, may increase your risk for salmonellosis. Talk to your doctor about this risk.
