About us - Dairy Laboratory Ltd

Our History

In January 2001, on the proposal from the Ministry of Agriculture relevant organizations and institutions interested in proper arrangement of milk market and herd improvement activities came together and decided to set up an independent joint milk quality testing laboratory.

The Dairy Laboratory Ltd. was founded on 13 August 2001 with a view to setting up of an independent raw milk quality testing laboratory that will carry out tests on raw milk for determination of the grade of delivered milk as well as for milk recording purposes.

Objective of the Laboratory is centralization of aggregate raw milk quality determination, allowing to provide independent results and to increase the volume of testing at the same time reducing testing costs. Independent results obtained in testing of aggregate milk, will increase the competitiveness of our milk producers on the EU market and will help to set Latvian domestic milk market in proper order.

In August 2002, Dairy laboratory Ltd. started implementation of the Danish-Latvian joint project on setting up of the Independent national Dairy Laboratory.

By the end of 2002, reconstruction of premises and furnishing of the laboratory in compliance with requirements of the standard ISO/IEC 17025 were finished.

The other scope of our Laboratory is performance of milk recording tests. Currently, there are three laboratories in Latvia carrying out tests for milk recording purpose. In time being, farmers will also need guarantees on reliability of test results and their receipt on due time. Reliability of test results is ensured by accreditation of the Laboratory.

Founders of the Dairy Laboratory Ltd. are public organizations involved in milk production, processing and establishments involved in implementation of the recording program as well as the State share. The structure of founders is built up in such a way as to prevent possibility to influence operation of the laboratory thus, securing independent and reliable results both for farmers and processors.
