Cronobacter Selective Broth (CSB) is recommended for screening Cronobacter (formerly Enterobacter sakazakii) from food. The composition and performance of this media are as per specifications laid down in ISO 22964:2017(E). It contains Peptone and HM extract that provide carbonaceous, nitrogenous compounds, long chain amino acids and other essential nutrients. Sodium chloride maintains osmotic equilibrium. Sucrose present is fermented by Cronobacter. Consequently the broth turns yellow after incubation.
