TECHNICAL SPECIFICATIONS REFERRED TO IN ARTICLE 3, ARTICLE 4 AND ARTICLE 5(2)(b)
Part A: Overview and sampling frame
Overview of the survey
The survey shall be performed according to the overview in Figure 1.
Overview of the survey
The survey shall be carried out on holdings harbouring at least 80 % of the breeding pig population in a MemberState. Preferentially holdings having 50 breeding pigs or more shall be sampled. However, if those holdingshaving 50 breeding pigs or more do not contain 80 % of the national herd of breeding pigs, then smallerholdings with less than 50 breeding pigs shall also be sampled.
Holdings with breeding pigs shall be classified either as ‘breeding holdings’ or as ‘production holdings’. Breedingholdings sell gilts and/or boars for breeding purposes. Typically, they sell 40 % or more of the gilts that they rearfor breeding whilst the remainder are sold for slaughter. In contrast, production holdings mainly sell pigs forfattening or slaughter.
and MRSA prevalence must be measured separately in breeding holdings (Part 1 of the Salmonella
and MRSA surveys) and in production holdings (Part 2 of the Salmonella
and MRSA surveys), representing theherds as indicated in Figure 2, but excluding weaner to finisher herds.
Overview of holdings
The sample and the sampling strategy
Both parts of the Salmonella
and MRSA surveys shall have a similar two-stage sampling design. In the first stage,a random sample of holdings shall be selected in every Member State from the breeding holdings and a secondrandom sample shall be selected from the production holdings group. The number of holdings required isdiscussed in section 2.3. In the second stage, a number of pens shall be selected for sampling within everyselected holding (see Section 2.2.2).
F i r s t s t a g e : s e l e c t i o n o f h o l d i n g s
Each Member State must create two sampling frames. The first shall list all eligible breeding holdings (usually,those holdings with at least 50 breeding pigs — see Section 2.1) and the second shall list all eligible productionholdings. The required number of holdings for each part of the Salmonella
and MRSA surveys will then beselected at random from each list. A random sample is intended to ensure that the surveys include holdings witha range of herd sizes and from all regions of a Member State where pig-keeping is practised. It is recognised thatin some Member States, there may be a few holdings (e.g. fewer than 10 % of all eligible holdings) with a verylarge herd size. Thus, random selection may by chance result in none of these very large herds being selected. AMember State may use a stratification criterion prior to holding selection — for example, to define a stratumcontaining the 10 % of largest herds and to allocate 10 % of the required sample size to this stratum. Similarly, aMember State may stratify the sample across administrative regions according to the proportion of eligible herdswithin each region. Any stratification that is considered should be described in the report that a Member Statesubmits to the Commission in accordance with Part D (1).
If a selected holding cannot be sampled (for example, if it no longer exists when sampling is carried out) a newholding shall be selected at random from the same sampling frame. If any stratification (e.g. on herd size orregion) was in operation, then the new holding should be selected from the same stratum.
The primary sample size (number of holdings to be sampled) shall be approximately equally distributed over theyear to cover the different seasons, as far as possible. Samples shall be taken from approximately one twelfth ofthe number of holdings each month.
Outdoor holdings must be included in the survey but there shall be no mandatory stratification on thisproduction type.
S e c o n d s t a g e : s a m p l i n g o n t h e h o l d i n g
In each selected breeding herd and production herd the pens, yards or groups of breeding pigs over six monthsof age to be sampled will be randomly selected.
The number of pens, yards, or groups to be sampled must be proportionally allocated according to the numbersof breeding pigs in the different stages of production (pregnant, non-pregnant, and other categories of breedingpigs). The exact age categories to be sampled are not prescribed, but this information shall be collected duringthe sampling.
Breeding pigs that have arrived recently to the herd and are held in quarantine shall not be included in theSalmonella
and MRSA surveys.
P r i m a r y s a m p l e s i z e ( f i r s t - s t a g e s a m p l e s i z e )
A regular primary sample size calculation shall be conducted for the breeding holdings and a second regularprimary sample size calculation shall be conducted for the production holdings. The primary sample size shall bethe number of breeding holdings to be sampled and the number of production holdings to be sampled in eachMember State and it shall be determined taking into account the following criteria, assuming simple randomsampling:
(a) the total number of breeding holdings (breeding holdings, Part 1 of the Salmonella
and MRSA surveys);
(b) the total number of production holdings (production holdings, Part 2 of the Salmonella
and MRSA surveys);
(c) annual expected prevalence (p): 50 %;
(d) desired confidence level (Z): 95 %, corresponding to a Zα value of 1,96;
The calculation shall be conducted firstly, for the breeding holdings and secondly, for the production holdings. Ineach case, the assumptions in steps c-e above are the same.
For practical purposes, if there are 100 000 or more holdings in either the breeding herds sampling frame or theproduction herds sampling frame then that population can be considered to be infinite and the number ofholdings to be randomly selected from that sampling frame is 171 (see Table 1). Where the number of breedingherds or production herds is less than 100 000 a finite population correction factor is applied and fewerholdings need to be sampled as shown in Table 1.
As an example, if there are in a Member State 1 000 holdings belonging to the production holding group and250 holdings belonging to the breeding holding group, 147 holdings must be sampled in the productionholding group and 102 holdings must be sampled in the breeding holding group.
Number of holdings with breeding pigs to sample in either part of the Salmonella and MRSA surveys as
a function of the finite population size (total number of holdings with breeding pigs in the Member
Number of holdings with breeding pigs (N)
Sample size (n) for finite population size 7,5 % accuracy
Non-response shall be anticipated e.g. by increasing the sample size in each group by 10 %. Any unsuitableholding shall be replaced in the process of the Salmonella
and MRSA surveys (see Section 2.2.1).
In case an estimation of the number of ‘breeding holdings’ is not possible prior to the start of the survey, anumber of holdings shall be selected for sampling as in Table 1 based on the total number of holdings withsows (X holdings). The number of holdings to be sampled shall be increased by at least 30 % ((X + 30 %)holdings). Prior to the survey, the competent authority shall identify a number of breeding holdings, equal toat least this additional 30 %. While visiting the farms, the holding will be classified as breeding or productionholding according to the definitions above.
S e c o n d a r y s a m p l e s i z e ( s e c o n d - s t a g e s a m p l e s i z e )
In each selected holding samples shall be collected from 10 randomly chosen pens, yards, or groups of breedingpigs. If necessary (for example, in farrowing accommodation or where sows are kept in small groups of less than10 individuals), a group can consist of more than one pen. At least 10 individual breeding pigs should contributeto each routine Salmonella
However, where on smallholdings or holdings with large numbers of breeding pigs kept outdoors in paddocks,the number of pens, yards or groups is less than 10, sampling of the same pen, yard, or group shall be requiredso that a total of 10 routine Salmonella
samples are submitted.
Part B: Sample collection and analysis for the Salmonella survey
Sample collection in the herds
Type and detail of the routine sample
The material collected for bacteriological analysis shall be freshly voided faeces representing the whole holding,which is the unit of interest. Since every holding is unique, it shall be decided, before starting the sampling,which pens, yards, or groups within the holding are sampled. The sample collected shall be placed in a separatecontainer avoiding cross-contamination and sent to the laboratory.
Each pooled sample shall total at least 25 g and two approaches may be employed to collect these pooled faecessamples:
1. where there is an accumulation of mixed faeces within an area of a pen or yard, a large swab (e.g.
20 cm × 20 cm) can be used to pass through the faecal mass, ensuring that at least 25 g of mixedmaterial is collected. This may be achieved by for example, moving the swab along a 2-metre zig-zagpath such that it is well coated with faecal material. If necessary, for example due to hot weather or onslatted flooring, then the swab may be moistened with an appropriate liquid such as drinking water.
2. where there is no such accumulation, for example in a field, large yard, in a farrowing house, or pens or other
accommodation with low numbers of pigs per group, then individual pinches shall be selected from indi-vidual fresh faecal masses or places so that a minimum of 10 individuals, contribute to a total sample volumeof at least 25 g. The sites from which these pinches are collected should be distributed in a representativemanner across the area concerned.
Approach 1 shall be preferred where practical. In this approach at least 10 individual pigs must contribute toeach sample taken, otherwise approach 2 shall be applied.
Additional sampling for the within-holding prevalence study
Together, 10 holdings, selected at random from the overall sample of breeding holdings and of productionholdings are subjected to more intensive sampling. On these holdings 10 routine samples shall be collected inthe same manner as described previously (Section 2.1 of Part A). In addition, 10 individual samples of at least30 g shall be collected in each selected pen and shall be identified in such a manner that these 10 individualsamples can be associated with the routine sample from that pen. Thus in total, 10 routine samples and 100(10 × 10) individual samples shall be collected from each of these 10 holdings. The processing of these samplesis described in Section 2.3.1.
This sampling should be applied in Czech Republic, Denmark, Romania, Slovenia, Sweden and the UnitedKingdom.
All relevant information available from the sample shall be recorded on a sampling form produced by thecompetent authority to enable the data requirements in Part D to be fulfilled.
Each sample and its sample form shall be labelled with a unique number which shall be used from sampling totesting, and with the code of the pen. The competent authority must arrange for the issue and use of a uniquenumbering system.
Samples shall be preferably kept between + 2 and + 8 °C and free of external contamination during transpor-tation. The samples shall be sent to the laboratory as quick as possible within 36 hours by fast mail or courierand shall reach the laboratory no later than 72 hours after sampling.
Laboratory analytical methods
Analysis and serotyping shall take place at the National Reference Laboratory (NRL). Where the NRL does nothave the capacity to perform all analyses or if it is not the laboratory that performs detection routinely, thecompetent authorities may decide to designate a limited number of other laboratories involved in official controlof Salmonella
to perform the analyses. These laboratories shall have proven experience of using the requireddetection method and have a quality assurance system complying with ISO 17025 and be submitted to thesupervision of the NRL.
At the laboratory, samples shall be kept refrigerated until bacteriological examination, which shall preferably becarried out within 24 hours after receipt but in any case no later than 96 hours after the sample was collected.
Member States shall guarantee that all involved parties have been sufficiently trained to carry out the analyses.
In the laboratory, routine samples shall be mixed carefully and thoroughly, before 25 g is collected for analysis.
For evaluation of the within-holding prevalence in accordance with paragraph 1.2, each of the individualcollected samples (30 g) needs to be divided into two parts. One part, weighing at least 25 g shall be mixedcarefully and thoroughly and subsequently cultured individually. The remaining second part is to be used toprepare an artificially pooled sample from the 10 individual samples in the selected pen, group or yard. Thislatter part shall be prepared by adding 10 times 2,5 g of the individual samples to create an artificially pooledsample of 25 g. The artificially pooled samples are mixed carefully and thoroughly before analysis. In total, 10routine samples, 10 artificially pooled sample and 100 individual samples shall be analysed from each of the 10holdings selected for the estimation of the within-holding prevalence.
D e t e c t i o n a n d i d e n t i f i c a t i o n m e t h o d s
The method recommended by the Community Reference Laboratory (CRL) for Salmonella
in Bilthoven, theNetherlands, shall be used. This method is described in the Annex D of ISO 6579: ‘Detection of Salmonella
spp. in animal faeces and in samples of the primary production stage’. The latest version of Annex D shall beused.
All strains isolated and confirmed as Salmonella
spp. shall be serotyped according to the Kaufmann-Whitescheme, by the NRL for Salmonella
For quality assurance, 16 typable strains and 16 non-typable isolates shall be sent to the CRL for Salmonella
. Aproportion of these isolates shall be sent to the CRL on a quarterly basis. If fewer strains have been isolated, allshall be sent.
18.104.22.168. Phage typing of Salmonella
In case isolates of Salmonella Enteritidis
and Salmonella Typhimurium
are phage typed (optional), the methodsdescribed by the WHO reference centre for phage typing of Salmonella
of the Health Protection Agency (HPA)Colindale, London, shall be used.
Part C: Sample collection and analysis for the MRSA survey
Type and detail of sample
Five dust samples shall be gathered using five dry sterile swabs of about 500 cm2 each from five of the 10 pensselected for sampling under part A. These five pens shall be chosen in a way that breeding pigs in differentproduction stages are included. For each pen dorsal surfaces of pen partition walls shall be swabbed. In case thereis not enough dust present, then ventilator ducts etc. shall be sampled in addition. After use, the soiled swabshall be placed in a sterile plastic bag.
The creation of aerosol in the building shall be avoided during sampling.
Each sample and its sample form shall be labelled with a unique number which shall be used from sampling totesting. The competent authority shall arrange for the issue and use of a unique numbering system.
Samples shall be kept at constant temperature between + 2 °C and 25 °C (room temperature) and free of externalcontamination during storage and transportation. The samples shall be sent to the laboratory as quickly aspossible and reach the laboratory no later than 10 days after sampling.
Laboratory analytical methods
Analysis and subtyping of MRSA shall take place in experienced laboratories. This shall preferably be theNational Reference Laboratories (NRL’s) for Staphylococcus aureus
and/or antimicrobial resistance in the MemberStates. In case the NRL does not have the capacity or experience to perform the analyses or if it is not thelaboratory that performs detection routinely, the competent authority shall decide to designate other experiencedlaboratories or a NRL in another Member State to perform the analyses. These laboratories shall have provenexperience of using the required methods and have an accreditation system in place according to ISO 17025. Anup-to-date list of authorised laboratories can be consulted on the website of the Community ReferenceLaboratory for antimicrobial resistance (CRL-AR) in Copenhagen, Denmark.
Samples arriving 10 days after sampling shall be discarded unless bacteriological examination can be startedwithin 13 days. At the laboratory, samples shall be kept at a constant temperature between + 2 °C and 25 °Cuntil bacteriological examination, which shall be carried out within 13 days after sampling.
In the laboratory the five dust swabs shall be pooled in a 100 ml of Mueller-Hinton broth supplemented with6,5 % NaCl and incubated at 37 °C for 16-20 h. One millilitre of this shall then be inoculated into 9 ml TryptoneSoy Broth + 3,5 mg/l cefoxitin and 75 mg aztreonam and shall be incubated for a further 16-20 h at 37 °C. Oneloop-full of this shall then be spread onto a chromogenic agar selective for MRSA and incubated for 24-48 h at37 °C. The specific agar recommended by the CRL-AR shall be used. This agar is described in the CRL-ARwebsite.
Based on colony morphology and colour, up to five colonies indicative for being MRSA shall be subcultivated onblood agar. Presumptive Staphylococcus aureus (S. aureus)
shall at this stage either be stored under appropriateconditions (– 80 °C) for later identification and characterisation or processed immediately.
Presumptive S. aureus
shall be identified as S. aureus
and MRSA by PCR. The identification shall be performedusing a multiplex PCR with simultaneous identification of the mecA-gene or two different PCR shall beperformed. To limit the amount of work only one of the five presumptive S. aureus
isolates shall initially beidentified. If this isolate is identified as MRSA, it shall be stored. No further testing of the remaining four isolatesis required if the first isolate is identified as MRSA and they can be discarded. If the first isolate is not identifiedas MRSA, the next of the initial five isolates shall be tested. This process shall continue until one MRSA has beenidentified or all five isolates have been tested. Alternatively, identification by PCR as a first step can be done on apool of the five presumptive colonies from a sample. In case of a positive PCR, the analysis shall be repeated onindividual colonies to identify a positive colony.
For quality assurance, 16 presumptive S. aureus
isolates which were not identified as MRSA, as well as 16 MRSAstrains, sampled over the whole year 2008 shall be sent to the CRL-AR. A proportion of these isolates shall besent to the CRL-AR on a quarterly basis. In case less than 16 isolates were verified as MRSA all these isolatesshall be sent.
S u b t y p i n g f o r p o s s i b l e l i n k t o h u m a n i s o l a t e s
Positive MRSA’s shall be tested for Staphylococcus
type A (Spa-typing). The typing shall be performed at the NRLor under its supervision, or isolates shall be forwarded to the CRL-AR, which shall then perform the typing.
On a subset of representative isolates (about 2 % of the number of pooled samples) MLST-typing shall beperformed by the NRL or the CRL-AR.
A n t i m i c r o b i a l s u s c e p t i b i l i t y t e s t i n g
Antimicrobial susceptibility testing is optional. If carried out, MRSA isolates shall be tested for antimicrobialsusceptibility using micro-dilution at least to the following antimicrobial agents: ciprofloxacin, erythromycin,fusidic acid, gentamicin, linezolide, mupirocin, sulphametoxazole, trimethoprim, tetracycline, chloramphenicol,vancomycin and quinupristin/dalfopristin. Reporting on antimicrobial susceptibility shall be carried out inaccordance with Article 9(1) of Directive 2003/99/EC.
The isolates shall be stored at the National Reference Laboratories (NRL’s) using the method for NRL culturecollection ensuring viability and no changes in properties of the strains for a minimum of five years. This is inorder to allow, for instance, later testing for antimicrobial susceptibility or other types of characterisation. Alsoisolates sent to the CRL-AR shall be stored for a minimum of five years. Isolates shall be stored under conditionsnot allowing changes in properties (– 80 °C). If the laboratory in charge do not have the available storagecapability, isolates shall be forwarded to the CRL-AR, which shall store these isolates.
Reporting from the laboratories
All analytical results shall be sent on a confidential basis only from the laboratory to the competent authority ofthe Member States where the dust samples were collected.

Complete data on each holding sampled and corresponding tests results:
The Member States shall submit the results of the Salmonella
and MRSA surveys electronically to the Commissionin the form of raw data using a data dictionary and data collection requirements established and provided by theCommission.
The following information shall be collected in Member States and transmitted to the Commission for eachholding selected for sampling:
(i) indoor versus ‘any stage of the production kept outdoors’;
(ii) nucleus, multiplier, farrow to weaner, farrow to finish and farrow to grower;
(c) holding size: the number of breeding pigs present at the time of sampling (adult inventory);
(d) replacement policy: all replacement breeding pigs purchased; some replacement breeding pigs homebred or
(e) (voluntarily) clinical symptoms of diarrhoea: were there symptoms of diarrhoea within the three months
Information on all samples collected within the Salmonella survey
The following information shall be collected in Member States for each sample sent to the laboratory within theframe of the Salmonella
(b) code of the laboratory involved in initial analysis;
(e) detection of Salmonella
: qualitative result (positive/negative);
serotyping of Salmonella
: serovar(s) detected (may be more than one);
(g) age of the pigs: all gilts versus mixed age breeding pigs;
(h) sex: only sows; sows and boars or only boars;
production stage: maternity; mating, gestation (other?);
housing: slatted floor (fully/partly); solid floor; deep straw or other;
(k) diet: are pigs in this pen, yard or group fed compound feed exclusively;
feed supplement: is there any Salmonella
reducing substance added to the feed (like organic acid, a probiotic);
(m) systematic use of antibiotics: are antibiotics used in all animals of this group by any route of administration;
(n) the last date of administration of antimicrobials to the animals (within the last four weeks).
Additional information on the samples collected within the Salmonella survey for the within holding prevalence
The following addition information shall be collected in Member States for each individual sample sent to thelaboratory within the frame of the sampling for the within-holding prevalence:
(b) detection of Salmonella
in each individual sample: qualitative result (positive/negative);
(c) serotyping of Salmonella
in each individual sample: serovar(s) detected (may be more than one).
Information on the samples collected within the MRSA survey
The following information shall be collected in Member States and for each sample sent to the laboratory:
(b) the code/name of the laboratory involved in the detection;
(e) the result of detection of MRSA (positive/negative);
(f) the code/name of the laboratory involved in the PCR;
(h) the code/name of the laboratory involved in the Spa typing;
