Invasive Cronobacter Infection in Infants

General information about invasive Cronobacter infection

Cronobacter infection in infants less than 12 months old is rare, but when it does happen, it can be serious. The infection starts with a fever and poor feeding, excessive crying, or very low energy. Some infants may experience seizures. A Cronobacter infection can also cause sepsis (a dangerous blood infection) and meningitis (when the linings surrounding the brain and spinal cord swell).

The Cronobacter germ lives naturally in the environment. It has also been found in water. The germ can live in dry foods like powdered infant formula, powdered milk, herbal teas, and starches.
