Salmonella species are Gram-negative, rod-shaped bacteria that live in the intestinal tracts of animals and birds and are one of the most well-known foodborne pathogens. Although other routes of infection exist, humans are usually infected through the ingestion of contaminated meat, poultry, milk, or eggs. However, the risk of infection for a healthy person remains low if food is properly handled and pasteurised/cooked fully.

There are many different serotypes of Salmonella but S. enteritidis and S. typhimurium are the most common strains found in Ireland. A person infected with S. enteritidis can experience abdominal cramps, headache, fever, and diarrhoea which usually last less than a week. More serious cases can result in hospital admission and can have serious implications for the elderly, infants, and immunocompromised population.

According to the Centres for Disease Control and Prevention (CDC), there were 53,169 confirmed cases of Salmonellosis in Europe in 2020 – 61 of which were fatal. The widely publicised Salmonella outbreak, which has been linked to Kinder chocolate, is believed to have led to 16 illnesses in Ireland and over 360 across Europe. Apart from the obvious negative impact on human health, outbreaks such as this can have serious ramifications for food manufacturers, both financially and in terms of brand perception and trust.

Does your facility test for Salmonella?

 MSC has a range of culture media, QC strains, and rapid detection methods to offer below.

Biokar Culture Media

IRIS Salmonella® Rapid Chromgenic Method (Afnor-validated)

CONFIRM' Salmonella - Latex agglutination kit BT01108, IRIS Salmonella®  | Medical Supply Company

IRIS Salmonella® is a rapid chromogenic method for the detection of Salmonella spp. in human food, feeds, and environmental samples. The method is AFNOR certified according to ISO 16140 standard and the agar can also be used as a secondary isolation medium.

IRIS Salmonella® provides results in under 48 hours, involving an 18-hour enrichment step and 24-hour plate incubation, followed by confirmation of presumptive colonies. The IRIS method also requires only 2 media: the supplemented enrichment broth and an IRIS agar plate.

How to confirm presumptive Salmonella?

  • Conventional tests described in standard methods CEN or ISO (including the purification step) using a colony isolated on IRIS Salmonella® Agar.
  • Latex test (CONFIRM Salmonella) made directly from a colony isolated on IRIS Salmonella® Agar.
  • Traditional Salmonella Media

MSC also offers all your traditional Salmonella media, including:

  • Bismuth Sulfite Agar (BSA)
  • Brilliant Green Agar (BGA)
