ISO 11133:2014 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.

This first edition of ISO 11133 replaces the second edition of ISO/TS 11133-1 (ISO/TS 11133-1:2009) and the first edition of ISO/TS 11133-2:2003, which have been technically revised. It also incorporates the Amendment ISO/TS 11133-2:2003/Amd.1:2011. In particular, it also includes requirements for microbiology media for water testing.

The International Standard ISO 11133 describes the preparation, production, storage and performance testing of culture media and the performance testing of reagents used in ISO standards for food and water microbiology.

EN ISO 11133 now also contains hands-on, detailed instructions for the maintenance of microbial strains as well as the preparation and standardization of working cultures and inoculation suspensions. The standard specifies the optimal number of colony forming units (cfu) per plate or membrane filter and describes how productivity ratios and ...

Microbiology of food, animal feed and water — Preparation, production, storage and performance testing of culture media — Amendment 2.

The one-part EN ISO 11133:2014, titled “Microbiology of food, animal feed and water – preparation, production, storage and performance testing of culture media”, was compiled by a joint ISO working group from food and water standardization.

In May 2014, the International Organization for Standardization (ISO) published the revised EN ISO 11133, which is now a full standard and as such, mandatory for all accredited laboratories that perform microbiological testing of food, animal feed or water using culture media.

ISO 11133:2014/Amd.2:2020(E) Annex K (normative) Performance testing of confirmation media and reagents This annex specifies control strains for the performance testing of confirmation and characterization media, reagents, dyes, stains and materials described in standards for the microbiological examination of samples from the food chain and water.
