Enterobacteriaceae test

Foss has announced a vial for the MicroFoss microbiological testing system which allows rapid testing for Enterobacteriaceae in a 9 mL buffered test vial.

Enterobacteriaceae is often required in the diary business in the production of products such as yoghurt, whey and milk powders.

Based on customer requests, an improved version of the Enterobacteriaceae test vial has been made available. Products which formerly needed to be diluted before testing in the MicroFoss Enterobacteriaceae test vial can now be tested directly in the new Enterobacteriaceae BP9 test vial, P/N 1024404.

The vial can also be used for very acidic products like yoghurt which formerly had to be diluted before testing. With the Enterobacteriaceae vial it can be tested directly by putting a 1 mL sample in the vial.

The vial works in the same way as the present Enterobacteriaceae vial, except that a diluent of 4 mL of buffer is already included in the vial. It complements existing MicroFoss tests for total viable count, Enterobacteriaceae, Coliform, generic E.coli, Lactic Acid Bacteria, yeast and the combined mould and yeast test.

The analysis principle used with MicroFoss is exactly the same as traditional microbiological testing, but the system exploits latest technology to simplify procedures and accelerate the delivery of results essential for food safety and quality. As soon as activity levels exceed limits or are found to be below required levels the MicroFoss system gives a visual indication on a computer connected to the system.
