BacSomatic raw milk bacteria test and somatic cell count

16. Apr, 2018
By Richard Mills,
The FOSS BacSomatic™ analyser has been granted certificate of compliance for enumeration of somatic cells as well as total bacterial count in raw cow’s milk by Microval - a certification organisation of the European Union.

The BacSomatic is a new analyser for rapid hygiene testing of raw milk and is the first-ever integrated bacteria and somatic cell tester.


To achieve the Microval certification, it has been evaluated and revealed to be at least equivalent with the reference method for somatic cell counting (ISO 13366-1:2008: Milk-Enumeration of somatic cells – part 1: Microscopic method) (Reference method).


Similarly, the instrument has been found to be at least equivalent to the reference method for total bacterial count (i.e., ISO 4833-1). The instrument has been evaluated according to ISO 8196-3, ISO 13366-2, ISO 16297, ISO 16140-2, and the criteria of the EU reference laboratory for somatic cell counting as well as total bacterial count.


What the certification means for BacSomatic users


The certification assures users that the BacSomatic has been tested thoroughly in a neutral laboratory and all test results complied with the requirements of the respective international ISO/IDF standards.  As a result, users do not need to test the instrument’s performance at their site. Moreover, the certificates open up the possibility to use the BacSomatic for official payment and regulatory testing purposes.


The certificates as well as the detailed test reports (one for somatic cell counting and one for bacterial counting) have been published on the Microval website:

More about BacSomatic


The BacSomatic gives dairy producers new powers to test the hygienic quality of milk on-the-spot. The rapid somatic cell and total bacteria count allows deliver­ies to be checked and segregated while sub-standard mate­rial can be rejected before it is used in the process.


As the first-ever integrated bacteria and somatic cell tester, BacSomatic offers a fast alternative to manual assay or semi-automated methods requiring reagent handling. Results for bacteria count are delivered within nine and a half minutes, whereas results for somatic cell count are delivered within one and a half minutes. The measurement principle is the same as that used in the well-known and established FOSS BactoScan™ and Fossomatic™analysers used by raw milk testing centres around the world.


BacSomatic is ideal for dairies and smaller laboratories needing only a low-volume, yet high-performance testing of bacteria and somatic cell count before milk flows into the dairy process.
