For detection and isolation of Salmonella species including lactose positive Salmonella.
Detection of lactose positive Salmonella is required in food microbiology by the ISO 6579-1 standard

Typical Appearance of microrganisms

Salmonella (including S. typhiS. paratyphi A and lactose positive Salmonella) → Mauve
E. coli → colourless
Coliforms, etc → blue
Proteus, etc → colourless or inhibited

Medium Performance

  1. Meets ISO 6579-1 requirements by detecting lactose positive Salmonella.

  2. Easy to read with the naked eye: Another feature of this new media resides in its nice colour contrast due to the fact that E. coli are colourless. E. coli, which are usually present in abundance in samples tested for Salmonella and can potentially hide suspect colonies, are no longer a concern.

  3. High Sensitivity and Specificity:
    Salmonella (including S. typhiS. paratyphi A and lactose positive Salmonella) → 99 %*
    *Specificity and sensitivity from scientific study: “Evaluation of a new chromogenic medium CHROMagar Salmonella Plus for the detection of Salmonella species including lactose positive Salmonella, S.Typhi and S.Paratyphi” de Beaumont C., Breuil J., Dedicova D., Tran Q. 2006. Poster presented during ECCMID meeting.

  4. Medium Description

Gain flexibility using powder rather than ready to use plates: Use the entire pack, or if there is a need for a smaller number of plates, just a portion. If kept under appropriate storage temperature, CHROMagarTM Salmonella Plus has a 3 years shelf life. This flexibility is essential to avoid the waste resulting from expired-unused plates. 
-Meets ISO 6579-1 requirements : Microbiology of food and animal feeding stuffs. Horizontal method for the detection of Salmonella spp. It is applicable to products intended for human consumption and the feeding of animals, and to environmental samples in the area of food production and food handling.

Please refer to our IFU and Material Safety data sheet for complete information about the medium.

Focus on Salmonella Species

Salmonella is a foodborne pathogen.
Infections caused by Salmonella spp., including Salmonella typhi, remain a major worldwide health problem:
- In the US, Salmonella has an incidence rate of 16.2 cases per 100,000 (CDC estimation, 2008).
- In Europe, it is reported as the first cause of collective toxi-infections. (2007 EFSA report) 
- In developing countries, Salmonella typhi and paratyphi are commonly encountered with an estimated annual incidence of about 17 million cases. (2007 EFSA report)

Moreover, according to a recent WHO report, Salmonella infections are responsible for 2 million deaths per year from diarrhoea.

Salmonella Epidemiologic Issues

Often present in meat, eggs and dairy products, Salmonella spp. are also found in water, with the serotypes S. typhi and S. paratyphi being responsible for typhoid and paratyphoid fever.
Salmonella surveillance represents the most common routine analysis in food chain processes. Consequently, improving the efficiency of the test will lead not only to a reduction in the number of contaminated foodstuffs on the market, but also to substantial economic savings in costs related to microbial quality control.
