Microbiological reference materials


The National Food Agency provides microbiological reference materials. These are used for internal control of analyses on laboratories and act as a complement to the proficiency testing programs.
There are different types of reference materials with freeze dried mixtures of microorganisms with no matrices. The freeze dried material, which is to be dissolved in a diluent, can be used for control of multiple parameters at the same time.

In addition to the above reference materials, we can also sometimes manufacture custom-made vials for individual laboratories. Most notably, we have a several different batches with different levels and species of Campylobacter available.

Manufacture of new vials is not guaranteed, and is only possible when our ordinary laboratory activities are not affected. In practice, this means you need to contact us at least 4 months prior to your requested deliviery date. Quality control and shipping of already manufactured Campylobacter batches can normally be done within 2 months.

Please contact us for more information on our current inventory, prices and the possibility of new manufacture.

We collect, process and store information about you/your laboratory in order to adminster your/your laboratory's order or samples from us. We also collect, process and store information to administer and evaluate your/your laboratory's participation in our PTs. The collected data will occasionally be used to send out various relevant information to you/your laboratory, or to ask for participation in surveys. Exceptionally, anonymised information may be shared with a third party at our discretion.
