EVS-EN ISO 11133:2014+A1:2018

This International Standard defines terms related to quality assurance of culture media and specifies
the requirements for the preparation of culture media intended for the microbiological analysis of food,
animal feed, and samples from the food or feed production environment as well as all kinds of water
intended for consumption or used in food production.
These requirements are applicable to all categories of culture media prepared for use in laboratories
performing microbiological analyses.
This document also sets criteria and describes methods for the performance testing of culture media. This document is applicable to end-users of ready-to-use culture media and to producers such as
— commercial bodies producing and/or distributing ready-to-use or semi-finished reconstituted or dehydrated media,
—  non-commercial bodies supplying media to third parties, and
—   microbiological laboratories preparing culture media for their own use.
