ISO 6887-5:2010(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6887-5 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 9,
Microbiology.
This first edition cancels and replaces ISO 8261|IDF 122:2001, which has been technically revised.
ISO 8261ΩIDF 122:2001 was elaborated by ISO/TC 34/SC 5, Milk and milk products, and, with its agreement,
has been renumbered as ISO 6887-5 and technically revised by ISO/TC 34/SC 9 with the following
modifications:
a) the introduction of buffered peptone water as a diluent for general use;
b) the systematic pre-heating of the diluent has been kept only for those cases where it resolves problems of
homogeneity of the suspension;
c) the reactivation step has been removed.
ISO 6887 consists of the following parts, under the general title Microbiology of food and animal feeding
stuffs — Preparation of test samples, initial suspension and decimal dilutions for microbiological examination:
⎯ Part 1: General rules for the preparation of the initial suspension and decimal dilutions
⎯ Part 2: Specific rules for the preparation of meat and meat products
⎯ Part 3: Specific rules for the preparation of fish and fishery products
⎯ Part 4: Specific rules for the pre
