How to estimate your measurement uncertainty (MU) that is related to quantitative determinations in microbiology of the food chain? You will find answers to your questions on this complex topic in the presentation of the approach of the recently revised standard ISO 19036:2019. A link to an Excel-based tool is also provided to support you in implementing the calculations of this International standard.
ISO 7218 is an essential standard to be used in conjunction with all ISO standardized reference methods for microbiological examinations carried out in the food chain. These include testing of food products, animal feeds, environmental samples in the area of food/feed production and handling, as well as samples from the primary production stage.

These standards are essential for all ISO standardized reference methods that describe the detection or enumeration of foodborne microorganisms. They describe how to prepare laboratory samples, make initial test suspensions and subsequent dilutions under optimal conditions to enhance recovery and maintain consistency between laboratories performing microbiological examination among the numerous matrices that exist for microbiological examination of food and feed throughout the food chain.

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.
Tables of reference strains to be used for performance testing are included in this article.
