Ensuring Safety of Powdered Infant Formulae

Oxoid has introduced two new 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 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 Sulphate 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.

Oxoid Cronobacter media form part of the extensive range of ISO compliant media for food and environmental testing available from Oxoid.
