Welcome to the Cronobacter Resource Centre hosted by the Irish Microbial Risk Assessment Network. The resource is divided into several sections as outlined below:


What is Cronobacter?

Cronobacter, formerly Enterobacter sakazakii, is a Gram-negative, motile, rod-shaped, non-sporulating pathogenic bacterium that can cause foodborne illness, primarily among infants and immunocompromised adults. Unlike some bacteria, it can survive in dried foods, like powdered infant formula. It can then multiply after liquid is added to the formula, especially if the formula is stored at an incorrect temperature, and cause illness in babies who drink it. Although the bacterium has also been found in a variety of other foods, only powdered infant formula has been linked to cases of illness. Taken from the Bad Bug Book - Foodborne Pathogenic Microorganisms and Natural Toxins - Second Edition.
