Extended range of ISO compliant culture media for food and environmental testing

We are pleased to announce the addition of four important culture media to the growing Oxoid range of ISO compliant products for the microbiological examination of food and environmental samples, allowing food microbiologists to be confident that the formulations meet the required ISO specifications.

Oxoid Modified Semi-solid Rappaport Vassiliadis (MSRV) Agar (ISO) is used for the selective enrichment of Salmonella species from food, environmental and animal faecal samples and conforms to ISO 6579:2002 Annex D.  This medium has been shown to detect more Salmonella positive samples than traditional enrichment procedures for animal faeces and environmental samples^1-4.

Oxoid Baird-Parker Agar (ISO) is a selective diagnostic medium for the isolation and enumeration of coagulase-positive staphylococci in foods.  Conforming to ISO 6888-1:1999, it is widely recommended by national and international bodies⁵.

The range also now includes Oxoid Violet Red Bile Lactose (VRBL) Agar (ISO), for the detection and enumeration of coliforms in food, animal feed and environmental samples, and Oxoid Violet Red Bile Glucose (VRBG) Agar (ISO), for the detection and enumeration of Enterobacteriaceae in food, animal feed and environmental samples.  These media conform to ISO 4823:2006 and ISO 21528-2:2004 respectively.

For further information about the extensive range of ISO complaint media available from Oxoid, please speak to your local Oxoid representative or contact Val Kane on tel: +44 (0)1256 841144, email: val.kane@thermofisher.com
