This document gives general requirements and guidance intended for three main uses:
─ implementation of ISO/TC 34/SC 9 or ISO/TC 34/SC 5 standards for detection or
enumeration of microorganisms, named hereafter “specific standards”;
─ good laboratory practices for food microbiology laboratories;
─ guidance for food microbiological laboratories on the technical requirements for accreditation to ISO/IEC 17025.
The requirements of this document supersede corresponding ones in existing specific standards.
Additional instructions for molecular biology examinations are specified in ISO 22174.
This document covers examination for bacteria, yeasts and moulds and can be used, if supplemented with specific guidance, for parasites and viruses. It is not applicable to examinations for toxins or other metabolites (e.g. amines) from microorganisms.
This document applies to microbiology of the food chain, including food, animal feed, the food production environment and primary production environment. This document is also applicable to the microbiological examination of water where water is used in food production or is regarded
as a food in national legislation.
The purpose of this document is to help to ensure the validity of food microbiology examinations. In particular to ensure that general techniques for conducting examinations are the same in all laboratories, to achieve consistent results in different laboratories, and to contribute to safety of
laboratory personnel by preventing risks of infection.

This document specifies minimum performance requirements for methods that quantify the food allergens milk, egg, peanut, hazelnut, almond, brazil nut, macadamia nut, cashew, pistachio nut, walnut, pecan nut, lupine, sesame, mustard, soy, celery, fish, molluscs, crustaceans, and wheat in raw and processed foodstuffs. Within the scope of this document, minimum requirements for an LOQ (Limit of Quantification) will be derived from threshold data of allergic consumers. For quantitative antibody-based methods, a normative annex will describe what specific information the method developer needs to deliver and how performance characteristics shall be validated. Regarding PCR and LC-MS/MS, information on performance characteristics are in parts covered by EN 15634-1 and EN 176441. This document does not apply to fragmented or hydrolysed food allergens, such as casein hydrolysates or soy sauce. It also does not apply to methods that deliver qualitative results only. Methods that cover gluten-containing cereals (wheat, rye, and barley) with regard to coeliac disease are covered by EN 17254.
