Cronobacter species media

Oxoid has introduced two culture media for the fast and reliable identification of Cronobacter species (formerly known as Enterobacter sakazakii) from food and environmental samples.

The ongoing development of a new horizontal CEN-ISO standard method for the detection of Cronobacter species by the ISO/TC 34, SC9 Ad hoc group for E. sakazakii addresses issues such as the scope of the method, reliability of identification criteria and improvements to the media. In anticipation of these future needs, Oxoid has launched Cronobacter Screening Broth (product code CM1121) and Chromogenic Cronobacter Isolation Agar (product code CM1122).

The Cronobacter media has been developed at the request of ISO/TC 34, SC 9, for the evaluation of the new horizontal ISO Standard for the isolation of Cronobacter spp. from food.

The Oxoid range also includes media that conform to current ISO requirements (ISO/TS 22964: 2006). This ISO method, which incorporates the use of buffered peptone water (CM1049), modified Lauryl Sulfate Tryptose Broth (CM1133 and SR0247) and Enterobacter sakazakii Isolation Agar (CM1134), allows the presumptive identification of Cronobacter spp. in just 72 hours, unlike the previous recommended method which could take up to seven days.
