Cronobacter Infection



are bacteria that can live in dry places. The bacteria are usually found in powdered baby formula, powdered milk, and herbal teas. An infection can be serious if you have a weak immune system, such as from HIV or cancer. Older adults may also develop a serious infection. An infection can cause inflammation around the brain, blood poisoning, or an intestine infection. Signs and symptoms include stomach pain and vomiting. You may also develop a urinary tract infection or wound infection.

Contact your healthcare provider if:

  • You have new or worsening signs or symptoms.
  • Your signs or symptoms do not get better with treatment.
  • You have questions or concerns about your condition or care.


in adults may not be needed. The bacteria may live in your body but not cause problems. You may be given antibiotics if you develop a urinary tract infection or wound infection.

Prevent a Cronobacter infection:

  • Wash your hands often. Wash your hands before you make a bottle with formula. Wash your hands after you cough or sneeze, use the bathroom, or change a baby's diaper. This can help prevent the spread of bacteria.
  • Use hot water to make tea or powdered milk. Most herbal teas and powdered milk products are safe. You can help protect yourself more by mixing leaf tea or powdered milk with water that is hot enough to kill bacteria (158°F or 70°C). Boil the water in a separate container. Do not put a thermometer into the water, because it may have bacteria on it.
