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.

Annex D
(normative)
Detection of Salmonella spp. in animal faeces and in environmental
samples from the primary production stage
D.1 Introduction
The method given in the main text of this International Standard is primarily intended for the isolation of
Salmonella spp. from food and feeding stuffs and is not always suitable for the detection of Salmonella spp.
from other matrices.
This annex is applicable to the detection of Salmonella spp. in
⎯ animal faeces (such as from poultry, pigs, cattle), and
⎯ environmental samples in the area of the primary production stage (such as dust).
The method in this annex is based upon Clause 9, with a different selective enrichment medium. Therefore,
where possible, reference will be made to Clause 9.
The selective enrichment medium as described in this annex (modified semi-solid Rappaport-Vassiliadis:
MSRV) is intended for the detection of motile Salmonellae and is not appropriate for the detection of
non-motile Salmonellae.
NOTE The non-motile Salmonella biovars of Salmonella Gallinarum (Salmonella Gallinarum biovar gallinarum and
Salmonella Gallinarum biovar pullorum do not seem to survive long in environmental samples and will therefore rarely be
detected in faecal or environmental (such as dust) samples (regardless of the method). The number of other non-motile
Salmonella serovars in faecal samples seems to be generally low. For example, in Reference [7] in which
circa 1 000 faecal samples of poultry layer flocks and circa 900 faecal samples of broiler flocks were analysed, less than
1 % of the total number of samples were positive in a selective broth and at the same time negative on MSRV (and likely
to be non-motile). Similar results were found in a Dutch study with circa 3 200 faecal samples of pigs (non-published data).
On the other hand, in the case of the study in Reference [7], up to almost 40 % of positive samples would not have been
detected (i.e. false negatives) if only a selective broth (in this case Rappaport Vassiliadis) had been used instead of a
semi-solid medium.
D.2 Principle
D.2.1 General
The detection of Salmonella in animal faeces and in samples of the primary production stage necessitates
four stages, as described in Clause 4.
D.2.2 Pre-enrichment in non-selective liquid medium
Buffered peptone water (BPW) is inoculated at ambient temperature with the test portion, then incubated
at 37 °C ± 1 °C for 18 h ± 2 h.
D.2.3 Enrichment on selective semi-solid medium
Modified semi-solid Rappaport-Vassiliadis (MSRV) agar plates are inoculated with the culture obtained
in D.2.2.

---------------------- Page: 8 ----------------------
ISO 6579:2002/Amd.1:2007(E)
The MSRV is incubated at 41,5 °C ± 1 °C for 24 h ± 3 h. If a plate is negative after 24 h, it is incubated for a
further 24 h ± 3 h.
D.2.4 Selective plating and identification
From the culture obtained in D.2.3, two selective solid media are inoculated:
⎯ xylose lysine deoxycholate (XLD) agar;
⎯ a
