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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 9, Microbiology.

This second edition cancels and replaces the first edition (ISO 13722:1996), which has been technically revised.

The main changes compared to the previous edition are as follows:

• the method specified in this document has been aligned with the NMKL (Nordic Committee on Food Analysis) method described in Reference [8];
• the title has been changed from ‘Meat and meat products’ into ‘Microbiology of the food chain’ and from ‘Enumeration of Brochothrix thermosphacta’ into ‘Enumeration of Brochothrix spp.’, and the scope has been changed accordingly;
• actidione (cycloheximide) has been omitted from the enumeration medium because of its toxicity;
• the catalase test has been added as confirmation test;
• validation data from an NMKL study^[8] have been included (Clause 11).

1 Scope

This document specifies a method for the enumeration of viable Brochothrix spp. by means of a colony-count technique.

This document is especially applicable to meat and meat products, but is also suitable for the examination of the following:

• other products intended for human consumption,
• products intended for animal feeding,
• environmental samples in the area of food and feed production, handling, and
• samples from the primary production stage.
