BS EN ISO 7218:2007+A1:2013

This International Standard gives general requirements and guidance/options intended for three main uses: implementation of ISO/TC34/SC9 or ISO/TC34/SC5 standards for detection or enumeration of microorganisms, named hereafter “specific standards”; good laboratory practice for food microbiological laboratories (the purpose is not to detail them in this International Standard, manuals are available for that purpose); guidance for accreditation of food microbiological laboratories (this International Standard describes the technical requirements according to AnnexB of ISO/IEC17025:2005 for the accreditation of a microbiological laboratory by national organizations). The requirements of this International Standard supersede the corresponding ones of existing specific standards. Additional instructions in the field of molecular biology examinations are specified in ISO22174 . This International Standard covers examination for bacteria, yeasts and moulds and can be used if supplemented with specific guidance for prions, parasites and viruses. It does not cover the examination for toxins or other metabolites (e.g. amines) from microorganisms. This International Standard applies to the microbiology of food, animal feeding stuffs, the food production environment and the primary production environment. The purpose of this International Standard is to help to ensure the validity of food microbiology examinations, to assist in ensuring that the general techniques used for conducting these examinations are the same in all laboratories, to help achieve homogeneous results in different laboratories, and to contribute towards the safety of the laboratory personnel by preventing risks of infection.
