Salmonella assay by counting

Bacteria of the genus Salmonella are among the main pathogens responsible for food poisoning. Their presence in foodstuffs or production environments poses a major health risk. Enumeration testing quantifies bacterial load and assesses product compliance with European and international regulations. This analysis is essential for controlling microbiological risks, protecting consumers, and ensuring product health traceability.

Analytical methods for the enumeration of Salmonella

Salmonella counting is based on different reference methods:

• Counting on specific culture media with enrichment, isolation and biochemical confirmation of suspect colonies.
• PCR (Polymerase Chain Reaction), which allows rapid and targeted detection of Salmonella bacteria DNA, even at low concentrations.
• DNA sequencing (NGS), used to characterize microbial diversity and precisely identify the strains present.

These methods comply with ISO 6579 or equivalent standards, ensuring international comparability of results. They complement other food safety analyses such as the enumeration of Escherichia coli or the detection of Listeria monocytogenes .

Industrial and regulatory applications

Salmonella testing by counting is essential in several sectors:

• Human food: meat, cold meats, fish, seafood, dairy products and eggs, where the presence of Salmonella is strictly controlled.
• Animal nutrition: controls on raw materials, flours and formulations intended for livestock.
• Nutraceuticals: verification of the microbiological quality of protein powders, plant extracts and food supplements.
• Environment and production areas: monitoring of the hygiene of equipment, process water and manufacturing areas.

These controls are in line with European regulations which require the absence of Salmonella in certain foodstuffs, and are part of a HACCP and ISO 22000 approach.

Matrices analyzed for Salmonella

YesWeLab supports Salmonella analysis in a wide range of matrices: meat, fish, dairy products, plant extracts, nutritional powders, dietary supplements, drinking water, and production surfaces. Each matrix is ​​specifically prepared to ensure reliable and representative results.

Security and compliance issues

Controlling the risk of Salmonella is essential for:

• Ensure the safety of consumers and animals.
• Meet strict regulatory requirements regarding food safety.
• Avoid batch recalls, financial losses and negative impact on brand image.
• Optimize industrial processes through rigorous monitoring of microbiological hygiene.

These analyses are part of a global quality control system, alongside other microbiological tests such as the counting of yeasts and molds or the quantification of enterobacteria .
