FAST AND ACCURATE DETECTION OF BACTERIA IN FOODS WITH OXOID CHROMOGENIC MEDIA

As one of the world’s leading suppliers of culture media, Oxoid is committed to the development of products that provide faster and easier bacterial identifications for the food industry. The use of innovative chromogenic substrates within the Oxoid Chromogenic Media range provides clearly visible answers on a single culture plate and often reduces or eliminates the need for further confirmatory testing.

Chromogenic technology detects specific enzyme activity in target organisms - quickly and accurately. These enzymes cleave a colourless substrate in the medium, releasing colour molecules within the colonies of interest and allowing them to be clearly seen, differentiated and counted.

The extensive selection of Oxoid Chromogenic Media available to the food industry includes:

• Oxoid Chromogenic Bacillus cereus Agar for the selective isolation and differentiation of Bacillus cereus.
• Oxoid Chromogenic E. coli/coliform Agar and Oxoid Selective E. coli/coliform Agar for the detection and differentiation of E. coli from other coliforms.
• Oxoid Chromogenic Enterobacter sakazakii Agar for the enumeration of Enterobacter sakazakii in infant milk and other foods and differentiation from other Enterobacteriaceae.
• Oxoid Chromogenic Salmonella Medium for the identification of Salmonella species and selective differentiation from other Enterobacteriaceae.
• Oxoid Chromogenic Listeria Agar for the improved isolation, enumeration and presumptive identification of Listeria species and differentiation of pathogenic Listeria monocytogenes and Listeria ivanovii from other Listeria species.
• Oxoid SMAC Agar + BCIG for the detection of E. coli O157 and differentiation from other E. coli.
• Oxoid TBX Agar for the detection and enumeration of E. coli in food samples.
