(Infection; Salmonella Enterica; Food Poisoning)
Salmonellosis is a type of food poisoning.
Salmonellosis is caused by certain bacteria. It grows in many places such as water, raw meat, seafood, and eggs. Infection comes from eating or drinking products with the bacteria. It can also come from contact with infected animals.
Once in the body, the bacteria enter the bowels where it can grow and cause problems.

The doctor will ask about symptoms and health history. You will also be asked about your food history or whether you work with animals. A physical exam will be done. Blood and stool (poop) tests will be done to look for signs of infection.
The infection usually goes away on its own in 2 to 5 days. Other care may involve:
- Fluids and electrolytes—given by IV or taken by mouth
- Medicines—to lower fever and ease pain
- Antibiotics—to treat people who have problems such as a blood infection
To lower the risk of food poisoning:
- Wash hands often.
- Wash cutting boards and kitchen tools with hot soapy water before and after handling raw foods.
- Use a different cutting board for raw meats.
- Do not eat or drink unpasteurized dairy products.
- Cook foods well. Use a thermometer to check them.
- Put foods in the refrigerator as soon as possible.
