It is essential to know if your Salmonella method still does what it is supposed to. Reliable results are essential. False-negative or false-positive results must be reduced to a minimum. Daily process control using certified reference material is a way to get insight into the method’s performance characteristics. Biosisto has five different types of Certified Reference Materials (CRM) Salmonella in stock.

Food-related CRM contains a Salmonella that can be found in food. To exclude cross-contamination with a food-related CRM, Salmonella, you can choose non-food-related Salmonella CRM. This non-food-related Salmonella you will very unlikely find in food samples.

You can also choose an a-typical Salmonella.

The choice depends on what the requirements of the laboratory are and what the laboratory prefers. Laboratories can use CRM for enumeration and detection methods.

In the table below, you will find the differences per Salmonella.

Quality in Control

Microbiological laboratories should be able to receive reliable analysis without much overhead. A microbiological analyst must be able to focus on the primary activities, for example analysis of the sample material. Quality control should support the analyst in a logical and simple manner. By using modern information technology, process control and quality assurance are designed smarter and more effective.
