COMMISSION IMPLEMENTING REGULATION (EU) 2015/1375

of 10 August 2015

laying down specific rules on official controls for

Trichinella

in meat

(Codification)

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 854/2004 of the European Parliament and of the Council of 29 April 2004 laying down specific rules for the organisation of official controls on products of animal origin intended for human consumption(1), and in particular points 9 and 10 of Article 18 thereof,

Whereas:

(1) Commission Regulation (EC) No 2075/2005(2) has been substantially amended several times(3). In the interests of clarity and rationality that Regulation should be codified.

(2) Regulation (EC) No 853/2004 of the European Parliament and of the Council(4), Regulation (EC) No 854/2004 and Regulation (EC) No 882/2004 of the European Parliament and of the Council(5) lay down the health rules and requirements regarding food of animal origin and the official controls required.

(3) In addition to those rules, more specific requirements should be laid down for

Trichinella

. Meat of domestic swine, wild boar, horses and other animal species may be infested with nematodes of the genus

Trichinella.

Consumption of meat infested with

Trichinella

can cause serious disease in humans. Measures should be put in place to prevent human disease caused by the consumption of meat infested with

Trichinella

(4) This Regulation should lay down rules for the sampling of carcasses of species susceptible to

Trichinella

infection, for the determination of the status of holdings and compartments and conditions for the import of meat into the Union. It should also provide for reference methods and equivalent methods for the detection of

Trichinella

in samples of carcasses.

(5) In order to facilitate the operation of cutting premises, the provision that allows the cutting of carcasses of domestic swine under certain conditions pending the results of the

Trichinella

examination, should also apply to horses under the same conditions.

(6) On 22 November 2001, the Scientific Committee on Veterinary Measures relating to Public Health adopted an opinion on trichinellosis, epidemiology, methods of detection and

Trichinella

-free pig production. On 1 December 2004, the Scientific Panel on Biological Hazards (Biohaz) of the European Food Safety Authority (EFSA) adopted an opinion on the suitability and details of freezing methods to allow human consumption of meat infected with

Trichinella

Cysticercus

. On 9 and 10 March 2005, Biohaz adopted an opinion on risk assessment of a revised inspection of slaughter animals in areas with low prevalence of

Trichinella.

(7) On 3 October 2011, EFSA adopted a Scientific Opinion on the public health hazards to be covered by inspection of meat (swine)(6). In that opinion, EFSA identified

Trichinella

as a medium risk for public health related to the consumption of pig meat and concludes that with respect to inspection methods for biological hazards, a pork carcass safety assurance, with a range of preventive measures and controls applied both on-farm and at slaughterhouse in an integrated way is the only way to ensure an effective control of the main hazards.

(8) EFSA identified certain epidemiological indicators in relation to

Trichinella

. Depending on the purpose and the epidemiological situation of the country, the indicators may be applied at national, regional, slaughterhouse or holding level.

(9) EFSA recognises the sporadic presence of

Trichinella

in the Union, mainly in free-ranging and backyard pigs. EFSA also identified that the type of production system is the single main risk factor for

Trichinella

infections. In addition, available data demonstrate that the risk of

Trichinella

infection in pigs from officially recognised controlled housing conditions is negligible.

(10) A negligible risk status for a country or region is no longer recognised in an international context by the World Organisation for Animal Health (OIE). Instead, such recognition is linked to compartments of one or more holdings applying specific controlled housing conditions.

(11) In order to enhance the control system in accordance with the actual public health risks, the

Trichinella

risk mitigation measures, including import conditions, at slaughterhouses and the conditions for determination of the

Trichinella

infection status of countries, regions or holdings should be laid down taking into account, inter alia, international standards.

(12) In 2011, Belgium and Denmark notified a

Trichinella

negligible risk for their territory in accordance with Regulation (EC) No 2075/2005. Such negligible risk status for a country or region is, however, no longer recognised. Nevertheless, holdings and compartments in Belgium and Denmark complying with the conditions for controlled housing on 1 June 2014 should be allowed to apply the derogation for such holdings and compartments without additional prerequisites such as further requirements of post-official recognition by the competent authority.

(13) It should be provided that the operators must ensure that dead animals are collected, identified and transported without undue delay in accordance with Articles 21 and 22 of Regulation (EC) No 1069/2009 of the European Parliament and of the Council(7) and with Annex VIII to Commission Regulation (EU) No 142/2011(8).

(14) The number of cases (imported and autochthonous) of

Trichinella

in humans, including epidemiological data, should be reported in accordance with Commission Decision 2000/96/EC(9).

(15) Information on the official recognition of the holding of origin as applying controlled housing conditions should be included by an official veterinarian in the animal health certificates provided for in Council Directive 64/432/EEC(10) as regards intra-Union trade in swine and in Commission Regulation (EU) No 206/2010(11) as regards imports into the Union of domestic swine from third countries in order to enable Member States to apply the appropriate

Trichinella

testing regime at slaughter and not to jeopardise the status of the holding of destination of swine for breeding or production.

(16) In order to ensure the correct application of this Regulation, third countries exporting domestic swine or meat thereof, should be listed in the relevant acts on import conditions if they apply the derogations on

Trichinella

sampling of domestic swine and if holdings or compartments are officially recognised as applying controlled housing conditions.

(17) The public health attestation of the

Trichinella

examination should be included in the veterinary certificates accompanying fresh meat in accordance with Regulation (EU) No 206/2010, meat preparations in accordance with Commission Decision 2000/572/EC(12) and meat products in accordance with Commission Decision 2007/777/EC(13).

(18) Various laboratory methods have been approved for the detection of

Trichinella

in fresh meat. The magnetic stirrer method for pooled-sample digestion is recommended as a reliable method for routine use. Sample size for parasitic analysis should be increased if the sample cannot be collected at the predilection site and if the type or species of animal is at higher risk of being infected. Trichinoscopic examination fails to detect non-encapsulated

Trichinella

species infecting domestic and sylvatic animals and humans and is no longer suitable as a detection method. Other methods, such as serological tests, can be useful for monitoring purposes once the tests have been validated by an EU reference laboratory appointed by the Commission. Serological tests are not suitable for detecting

Trichinella

infestation in individual animals intended for human consumption.

(19) New apparatus for

Trichinella

testing using the digestion method equivalent to the reference method started being produced by private companies. In line with these developments, guidelines for the validation of new apparatus for testing of

Trichinella

by the digestion method were endorsed unanimously during the meeting of the Standing Committee on the Food Chain and Animal Health on 16 December 2008.

(20) In accordance with those guidelines, in 2010 the EU reference laboratory for parasites validated a new apparatus method for testing of

Trichinella

in domestic swine under the code No EURLP_D_001/2011(14).

(21) Freezing meat under specified conditions can kill any parasites present but certain

Trichinella

species occurring in game and horses are resistant when freezing is carried out using the recommended temperature and time combinations.

(22) Regular monitoring of domestic swine, wild boar, horses and foxes or other indicator animals is an important tool for assessing changes in disease prevalence. The results of such monitoring should be communicated in an annual report in accordance with Directive 2003/99/EC of the European Parliament and of the Council(15).

(23) This Regulation generally does not allow meat of domestic swine to leave slaughterhouses before the results of examination for

Trichinella

infestation have been communicated to the official veterinarian. However, it is appropriate to allow, under certain strict conditions, to apply the health mark and release the meat for transport before the results are known. Under such circumstances it is essential that the competent authority verifies that full traceability of the released meat is in place at all times.

(24) Regulation (EC) No 853/2004 does not apply to wild game or wild game meat directly supplied to the final consumer or to local retail establishments directly supplying the final consumer. It should therefore be the responsibility of the Member States to adopt national measures to mitigate the risk of

Trichinella

-infested wild boar meat reaching the final consumer.

(25) The measures provided in this Regulation are in accordance with the opinion of the Standing Committee on Plants, Animals, Food and Feed,

HAS ADOPTED THIS REGULATION:

CHAPTER I

1. For the purposes of this Regulation, the competent authority may officially recognise a holding or a compartment applying controlled housing conditions where the requirements laid down in Annex IV are complied with.

2. Holdings or a compartment applying controlled housing conditions in Belgium or Denmark, in accordance with Article 3(3)(c), on 1 June 2014 shall be considered to be officially recognised as applying controlled housing conditions as listed in Annex IV.

Article 9

Obligation on food business operators to inform

Food business operators of holdings officially recognised as applying controlled housing conditions shall inform the competent authority of any requirement as laid down in Annex IV that is no longer fulfilled or of any other change that might affect the

Trichinella

status of those holdings.

Article 10

Audits of holdings officially recognised as applying controlled housing conditions

The competent authority shall ensure that audits are carried out periodically of holdings officially recognised as applying controlled housing conditions.

The frequency of the audits shall be risk-based, taking account of the disease history and the prevalence, previous findings, the geographical area, local susceptible wildlife, animal husbandry practices, veterinary supervision and farmers' compliance.

The competent authority shall verify that domestic swine coming from those holdings are examined in accordance with Article 2(1).

Article 11

Monitoring programmes

The competent authority may implement a monitoring programme covering the population of domestic swine coming from a holding or a compartment officially recognised as applying controlled housing conditions, in order to verify that

Trichinella

is actually absent in that population.

The frequency of testing, the number of animals to be tested and the sampling plan shall be laid down in the monitoring programme. To that end, meat samples shall be collected and examined for the presence of

Trichinella

parasites in accordance with Chapter I or II of Annex I.

The monitoring programme may include serological methods as an additional tool once a suitable test is validated by the EU reference laboratory.

Article 12

Withdrawal of official recognition of holdings as applying controlled housing conditions

1. Where the results of the audits carried out in accordance with Article 10 show that the requirements of Annex IV are no longer fulfilled, the competent authority shall withdraw the holding's official recognition without delay.

2. Where domestic swine from a holding officially recognised as applying controlled housing conditions test positive to

Trichinella

, the competent authority shall without delay:

(a) withdraw the holding's official recognition;

(b) examine all domestic swine of that holding at the time of slaughter;

(c) trace and test all breeding animals that arrived on the holding and, as far as possible, all those that left the holding in at least the six months preceding the positive finding; to that end, meat samples shall be collected and examined for presence of

Trichinella

parasites using the detection methods laid down in Chapters I and II of Annex I;

(d) when relevant, as far as is feasible, investigate the spread of parasite infestation due to the distribution of meat from domestic swine slaughtered in the period preceding the positive finding;

(e) inform the Commission and the other Member States;

(f) when relevant, initiate an epidemiological investigation to elucidate the cause of infestation;

(g) take appropriate measures where any infested carcass cannot be identified at the slaughterhouse, including:

(i) increasing the size of each meat sample collected for testing of the suspect carcasses; or

(ii) declaring the carcasses unfit for human consumption;

(iii) taking appropriate measures for the disposal of suspect carcasses or parts thereof and those testing positive.

3. Following withdrawal of the recognition, holdings may be officially recognised again once the problems identified have been solved and the requirements laid down in Annex IV are fulfilled to the satisfaction of the competent authority.

4. If the inspection identified a lack of compliance with Article 9 or positive testing in a holding of a compartment, the holding concerned shall be removed from the compartment until compliance is re-established.

CHAPTER III

ANNEX I

Detection methods

CHAPTER I

REFERENCE METHOD OF DETECTION

Magnetic stirrer method for pooled sample digestion

1. Apparatus and reagents

(a) Knife or scissors and tweezers for cutting specimens.

(b) Trays marked off into 50 squares, each of which can hold samples of approximately 2 g of meat, or other tools giving equivalent guarantees as regards the traceability of the samples.

(c) A blender with a sharp chopping blade. Where the samples are larger than 3 g, a meat mincer with openings of 2 to 4 mm or scissors must be used. In the case of frozen meat or tongue (after removal of the superficial layer, which cannot be digested), a meat mincer is necessary and the sample size will need to be increased considerably.

(d) Magnetic stirrers with thermostatically controlled heating plate and Teflon-coated stirring rods approximately 5 cm long.

(e) Conical glass separation funnels, capacity of at least 2 litres, preferably fitted with Teflon safety plugs.

(f) Stands, rings and clamps.

(g) Sieves, mesh size 180 microns, external diameter 11 cm, with stainless steel mesh.

(h) Funnels, internal diameter not less than 12 cm, to support the sieves.

(i) Glass beakers, capacity 3 litres.

(j) Glass measuring cylinders, capacity 50 to 100 ml, or centrifuge tubes.

(k) A trichinoscope with a horizontal table or a stereo-microscope, with a substage transmitted light source of adjustable intensity.

(l) A number of 9 cm diameter petri dishes (for use with a stereo-microscope), marked on their undersides into 10 × 10 mm square examination areas using a pointed instrument.

(m) A larval counting basin (for use with a trichinoscope), made of 3 mm thick acrylic plates as follows:

(i) the bottom of the basin to be 180 × 40 mm, marked off into squares,

(ii) the sides to be 230 × 20 mm,

(iii) the end to be 40 × 20 mm. The bottom and the ends must be inserted between the sides, to form two small handles at the ends. The upper side of the bottom must be raised 7 to 9 mm from the base of the frame formed by the sides and the ends. The components must be stuck together with glue suitable for the material.

(n) Aluminium foil.

(o) 25 % hydrochloric acid.

(p) Pepsin, strength: 1:10 000 NF (US National Formulary) corresponding to 1:12 500 BP (British Pharmacopoeia) and to 2 000 FIP (Fédération internationale de pharmacie), or stabilised liquid pepsin with minimum 660 European Pharmacopoeia units/ml.

(q) Tap water heated to 46 to 48 °C.

(r) A balance accurate to at least 0,1 g.

(s) Metal trays, capacity 10 to 15 litres, to collect the remaining digestive juice.

(t) Pipettes of different sizes (1, 10 and 25 ml) and pipette holders.

(u) A thermometer accurate to 0,5 °C within the range 1 to 100 °C.

(v) Siphon for tap water.

2. Collecting of specimens and quantity to be digested

(a) In the case of whole carcasses of domestic swine, a specimen weighing at least 1 g is to be taken from a pillar of the diaphragm at the transition to the sinewy part. Special trichinae forceps can be used provided an accuracy of between 1,00 and 1,15 g can be guaranteed.

In the case of breeding sows and boars, a larger sample weighing at least 2 g is to be taken from a pillar of the diaphragm at the transition to the sinewy part.

In the absence of diaphragm pillars, a specimen of twice the size 2 g (or 4 g in the case of breeding sows and boars) is to be taken from the rib part or the breastbone part of the diaphragm, or from the jaw muscle, tongue or abdominal muscles.

(b) For cuts of meat, a sample weighing at least 5 g of striated muscle, containing little fat is to be taken, where possible from close to bones or tendons. A sample of the same size is to be collected from meat that is not intended to be cooked thoroughly or other types of post-slaughter processing.

The weight of meat specimens relates to a sample of meat that is free of all fat and fascia. Special attention must be paid when collecting muscle samples from the tongue in order to avoid contamination with the superficial layer of the tongue, which is indigestible and can prevent reading of the sediment.

3. Procedure

I. Complete pools (100 g of samples at a time)

(a) 16 ± 0,5 ml of hydrochloric acid is added to a 3 litre beaker containing 2,0 litre of tap water, preheated to 46 to 48 °C; a stirring rod is placed in the beaker, the beaker is placed on the preheated plate and the stirring is started.

(b) 10 ± 0,2 g of pepsin or 30 ± 0,5 ml liquid pepsin is added.

(d) The chopped meat is transferred to the 3 litre beaker containing the water, pepsin and hydrochloric acid.

(e) The mincing insert of the blender is immersed repeatedly in the digestion fluid in the beaker and the blender bowl is rinsed with a small quantity of digestion fluid to remove any meat still adhering.

(f) The beaker is covered with aluminium foil.

(g) The magnetic stirrer must be adjusted so that it maintains a constant temperature of 44 to 46 °C throughout the operation. During stirring, the digestion fluid must rotate at a sufficiently high speed to create a deep whirl without splashing.

(h) The digestion fluid is stirred until the meat particles disappear (approximately 30 minutes). The stirrer is then switched off and the digestion fluid is poured through the sieve into the sedimentation funnel. Longer digestion times may be necessary (not exceeding 60 minutes) in the processing of certain types of meat (tongue, game meat, etc.).

(i) The digestion process is considered satisfactory if not more than 5 % of the starting sample weight remains on the sieve.

(j) The digestion fluid is allowed to stand in the funnel for 30 minutes.

(k) After 30 minutes, a 40 ml sample of digestion fluid is quickly run off into the measuring cylinder or centrifuge tube.

(l) The digestion fluids and other liquid waste are kept in a tray until reading of the results is completed.

(m) The 40 ml sample is allowed to stand for 10 minutes. 30 ml of supernatant is then carefully withdrawn by suction to remove the upper layers and leave a volume of not more than 10 ml.

(n) The remaining 10 ml sample of sediment is poured into a larval counting basin or petri dish.

(o) The cylinder or centrifuge tube is rinsed with not more than 10 ml of tap water, which has to be added to the sample in the larval counting basin or petri dish. Subsequently, the sample is examined by trichinoscope or stereo-microscope at a 15 to 20 times magnification. Visualisation using other techniques is allowed, provided examination of positive control samples has been shown to give an equal or better result than traditional visualisation methods. In all cases of suspect areas or parasite-like shapes, higher magnifications of 60 to 100 times must be used.

(p) Digests are to be examined as soon as they are ready. Under no circumstances should examination be postponed until the following day.

Where the digests are not examined within 30 minutes of preparation, they must be clarified as follows. The final sample of about 40 ml is poured into a measuring cylinder and allowed to stand for 10 minutes. 30 ml of the supernatant fluid is then removed, leaving a volume of 10 ml. This volume is made up to 40 ml with tap water. After a further settling period of 10 minutes, 30 ml of the supernatant fluid is withdrawn by suction, leaving a volume of no more than 10 ml for examination in a petri dish or larval counting basin. The measuring cylinder is washed with no more than 10 ml of tap water and these washings are added to the sample in the petri dish or the larval counting basin for examination.

If the sediment is found to be unclear on examination, the sample is poured into a measuring cylinder and made up to 40 ml with tap water and then the procedure described in this Section is followed. The procedure can be repeated 2 to 4 times until the fluid is clear enough for a reliable reading.

II. Pools of less than 100 g

Where needed, up to 15 g can be added to a total pool of 100 g and examined together with these samples in accordance with Section I. More than 15 g must be examined as a complete pool. For pools of up to 50 g, the digestion fluid and the ingredients may be reduced to 1 litre of water, 8 ml of hydrochloric acid and 5 g of pepsin.

III. Positive or doubtful results

Where examination of a collective sample produces a positive or uncertain result, a further 20 g sample is taken from each pig in accordance with point 2(a). The 20 g samples from five pigs are pooled and examined using the method described in this Chapter. In this way samples from 20 groups of five pigs will be examined.

When

Trichinella

is detected in a pooled sample from five pigs, further 20 g samples are collected from the individual pigs in the group and each is examined separately using the method described in this Chapter.

Parasite samples are to be kept in 90 % ethyl alcohol for conservation and identification at species level at the EU or national reference laboratory.

After parasite collection, positive fluids (digestive juice, supernatant fluid, washings, etc.) are to be decontaminated by heating to at least 60 °C.

IV. Cleaning and decontamination procedure after a positive or doubtful result

When the examination of a collective or individual sample produces a positive or doubtful result, all material in contact with meat (blender bowl and blade, beaker, stirring rod, temperature sensor, conical filtration funnel, sieve and forceps) must be carefully decontaminated by washing in warm water (65 to 90 °C). It is recommended to rinse each piece thoroughly to remove the detergent if a detergent is used during washing.

II. Digestion procedure

This procedure may involve complete pools (100 g of samples at a time) or pools of less than 100 g.

(a) Complete pools (100 samples at a time):

(i) The Stomacher lab-blender 3 500 is fitted with a double plastic bag and the temperature control set at 40 to 41 °C.

(ii) One and a half litres of water preheated to 40 to 41 °C is poured into the inner plastic bag.

(iv) 100 samples weighing approximately 1 g each (at 25 to 30 °C) taken from each individual sample in accordance with point 2 are added.

(v) Lastly, 6 g pepsin or 18 ml liquid pepsin is added. This order must be followed strictly to avoid decomposition of the pepsin.

(vi) The Stomacher is then allowed to pound the content of the bag for 25 minutes.

(vii) The plastic bag is removed from the Stomacher and the digestion fluid is filtered through the sieve into a 3 litre beaker.

(viii)

The plastic bag is washed with approximately 100 ml of water, which is then used to rinse the sieve and lastly added to the filtrate in the beaker.

(ix) Up to 15 individual samples can be added to a total pool of 100 samples and examined together with these samples.

(b) Smaller pools (less than 100 samples):

(i) The Stomacher lab-blender 3 500 is fitted with a double plastic bag and the temperature control set at 40 to 41 °C.

(ii) A digestion fluid is prepared by mixing about one and a half litres of water and 25 ml of 17,5 % hydrochloric acid. 6 g of pepsin is added and the whole mixed at a temperature of 40 to 41 °C. This order must be followed strictly to avoid decomposition of the pepsin.

(iii) Of the digestion fluid, a volume corresponding to 15 ml per gram of sample is measured (e.g. for 30 samples the volume required is 30 × 15 ml = 450 ml) and transferred to the inner of the two plastic bags, together with the meat samples weighing approximately 1 g (at 25 to 30 °C) taken from each individual sample in accordance with point 2.

(iv) Water at a temperature of approximately 41 °C is poured into the outer bag to make up a total volume in the two bags of one and a half litres. The Stomacher is then allowed to pound the content of the bag for 25 minutes.

(v) The plastic bag is removed from the Stomacher and the digestion fluid is filtered through the sieve into a 3 litre beaker.

(vi) The plastic bag is washed with approximately 100 ml of water (at 25 to 30 °C), which is then used to rinse the sieve and lastly added to the filtrate in the beaker.

III. Recovery of larvae by sedimentation

— Ice (300 to 400 g of ice flakes, scaly ice or crushed ice) is added to the digestion fluid to bring its volume up to about 2 litres. The digestion fluid is then stirred until the ice has melted. In the case of smaller pools (see Section II(b)), the amount of ice must be reduced correspondingly.

— The chilled digestion fluid is transferred to a 2 litre separation funnel, equipped with a vibrator in an extra clamp.

— Sedimentation is allowed to proceed for 30 minutes, during which time the sedimentation funnel is vibrated intermittently, i.e. one minute vibration followed by a one-minute pause.

— After 30 minutes, a 60 ml sample of the sediment is quickly run off into a 100 ml measuring cylinder (the funnel is rinsed with detergent solution after use).

— The 60 ml sample is allowed to stand for at least 10 minutes, after which time the supernatant is withdrawn by suction to leave a volume of 15 ml, to be examined for presence of larvae.

— For suction, a disposable syringe, equipped with a plastic tube, can be used. The length of the tube must be such that 15 ml remains in the measuring cylinder when the flanges of the syringe rest on the cylinder's rim.

— The remaining 15 ml is poured into a larval counting basin or two petri dishes and examined using a trichinoscope or stereo-microscope.

— The measuring cylinder is washed with 5 to 10 ml of tap water and the washings are added to the sample.

— Digests are to be examined as soon as they are ready. Under no circumstances is examination to be postponed until the following day.

Where the digests are unclear or they are not examined within 30 minutes of their preparation, they must be clarified as follows:

— the final sample of 60 ml is poured into a measuring cylinder and allowed to stand for 10 minutes; 45 ml of supernatant fluid is then removed by suction and the remaining 15 ml is made up to 45 ml with tap water,

— after a further settling period of 10 minutes, 30 ml of supernatant fluid is removed by suction and the remaining 15 ml is poured into a petri dish or larval counting basin for examination,

(c) The Gelman funnel, fitted with a filter holder and filter disc, is mounted on an Erlenmeyer flask connected to a filter pump.

(d) The digestion fluid is poured into the Gelman funnel and filtered. Towards the end of filtration, the digestion fluid can be helped to pass through the filter by applying suction with the filter pump. Suction must cease before the filter becomes dry, i.e. when 2 to 5 ml of fluid is left in the funnel.

(e) Once all the digestion fluid has been filtered, the filter disc is removed and placed in an 80 ml capacity plastic bag, together with 15 to 20 ml of rennilase solution. The rennilase solution is made by adding 2 g of rennilase to 100 ml of tap water.

(f) The plastic bag is sealed twice and placed between the inner and outer bags in the Stomacher.

(g) The Stomacher is allowed to pound for three minutes, e.g. while it is working on a complete or incomplete pool.

(h) After three minutes, the plastic bag, complete with filter disc and rennilase solution, is removed from the Stomacher and opened with scissors. The liquid contents are poured into a larval counting basin or petri dish. The bag is washed out with 5 to 10 ml of water, which is then added to the larval counting basin for examination by trichinoscope or to the petri dish for examination by stereo-microscope.

(i) Digests must be examined as soon as they are ready. Under no circumstances is examination to be postponed until the following day.

Note:

Filter discs must never be used when not completely clean. Unclean discs must never be allowed to dry out. Filter discs can be cleaned by leaving them in rennilase solution overnight. Before use, they must be washed in fresh rennilase solution using the Stomacher.

(b) 10 ± 1 g of powder pepsin (or 30 ± 3 ml of liquid pepsin) is added.

(c) 100-115 g of samples collected in accordance with point 2 are chopped in the blender, with 150 ± 15 ml of preheated digestion buffer.

(d) The chopped meat is transferred to the 3 litre beaker containing the water, pepsin and hydrochloric acid.

(f) The beaker is covered with aluminium foil.

(i) The digestion process is considered satisfactory if not more than 5 % of the starting sample weight remains on the sieve.

(j) The 20 microns nylon mesh filter is placed on the filtration support. The conical filtration steel funnel is fixed to the support with the block system and the steel sieve of 180 microns mesh size is placed on the funnel. The vacuum pump is connected with the filtration support and with the metal or plastic tank, to collect the digestive fluid.

(k) Stirring is stopped and the digestion fluid is poured into the filtration funnel through the sieve. The beaker is rinsed with approximately 250 ml of warm water. The rinsing liquid is poured into the filtration ramp after the digested fluid has been successfully filtrated.

(l) The filtration membrane is taken with the forceps, holding it by an edge. The filtration membrane is folded (minimal) in four and put in the 15 ml conical tube. The choice of conical tube must be adapted to the pestle.

(m) The filtration membrane is pushed at the bottom of the 15 ml conical tube with the help of the pestle and strongly pressed by doing approximately 20 successive back and forth movements with the pestle which should be positioned inside the filtration membrane folding according to the manufacturer's instructions.

(n) 0,5 ± 0,01 ml of sample diluents is added into the 15 ml conical tube by pipette and the filtration membrane is homogenised with the pestle by doing successive low amplitude back and forth movements for approximately 30 seconds, avoiding abrupt movements to limit liquid splashes according to the manufacturer's instructions.

(o) Each sample, the negative control, and the positive control, are dispensed into different fields of the agglutination card by pipettes, according to the manufacturer's instructions.

(p) The latex beads are added into each field of the agglutination card by a pipette, according to the manufacturer's instructions, without making them come into contact with the sample/s and controls. In each field, the latex beads are then gently mixed with a disposable stick until the homogeneous liquid covers the entire field.

(q) The agglutination card is put on the 3D rocker and is rocked for 10 ± 1 minutes according to the manufacturer's instructions.

(r) After the time established by the manufacturer's instructions, the rocking is stopped and the agglutination card is put on a plane surface and the reaction results are read immediately, according to the manufacturer's instructions. In the case of a positive sample, the beads aggregates must appear. In the case of a negative sample, the suspension remains homogeneous without beads aggregates.

II. Pools of less than 100 g as set out in Chapter I(3)(II)

For pools of less than 100 g, the procedure set out in Chapter I(3)(II) must be followed.

III. Positive or doubtful results

Where examination of a collective sample produces a positive or uncertain latex agglutination result, a further 20 g sample is taken from each swine in accordance with Chapter I(2)(a). The 20 g samples from five swine are pooled and examined using the method described in Section I. In this way samples from 20 groups of five swine must be examined.

When a positive latex agglutination is obtained from a group of five swine, further 20 g samples are collected from the individuals in the group and each is examined separately using the method described in Section I.

When a positive or uncertain latex agglutination result is obtained, at least 20 g of swine muscle must be sent to the national reference laboratory for confirmation using one of the methods described in Chapter I.

Parasite samples must be kept in 90 % ethyl alcohol for conservation and identification at species level at the EU or national reference laboratory.

After parasite collection, positive fluids must be decontaminated by heating to at least 60 °C.

IV. Cleaning and decontamination procedure after a positive or doubtful result

When the examination of a collective or individual sample produces a positive or doubtful latex agglutination result, all material in contact with meat (blender bowl and blade, pestle, beaker, stirring rod, temperature sensor, conical filtration funnel, sieve and forceps) must be carefully decontaminated by soaking for few seconds in warm water (65 to 90 °C). Meat residues or inactivated larvae that could remain on their surface may be removed with a clean sponge and tap water. If required, a few drops of detergent can be added for degreasing equipment. It is then recommended to rinse each piece thoroughly to remove all traces of detergent.

(b) The temperature is to be measured using calibrated thermo-electric instruments and recorded continuously. The thermometer probe is inserted in the centre of a cut of meat no smaller in size than the thickest piece of meat to be frozen. This cut must be placed at the least favourable position in the refrigeration room, not close to the cooling equipment or directly in the cold airflow. The instruments must be kept under lock and key. The temperature charts must include the data numbers from the meat inspection register on import and the date and time of commencement and completion of freezing, and must be retained for one year after compilation.

ANNEX III

Examination of animals other than swine

Horse meat, wild game meat and other meat that could contain

Trichinella

parasites must be examined in accordance with one of the digestion methods specified in Chapter I or II of Annex I, with the following changes:

(a) specimens weighing at least 10 g are taken from the lingual or jaw muscle of horses and from the foreleg, tongue or diaphragm of wild boar;

(b) in the case of horses, where those muscles are lacking, a larger-sized specimen is to be taken from a pillar of the diaphragm at the transition to the sinewy part. The muscle must be clean of connective tissue and fat;

(c) at least 5 g of sample is digested following the reference method of detection set out in Chapter I or an equivalent method set out in Chapter II. For each digest, the total weight of muscle examined must not exceed 100 g in the case of the method set out in Chapter I and methods A and B set out in Chapter II and 35 g in the case of method C set out in Chapter II;

(d) where the result is positive, a further 50 g specimen is taken for a subsequent independent examination;

(e) without prejudice to the rules on conservation of animal species, all meat of game animals other than wild boar, such as bears, carnivorous mammals (including marine mammals) and reptiles, are to be tested by sampling 10 g of muscle at the predilection sites or larger amounts if those sites are not available. Predilection sites are:

(i) in bears: diaphragm, masseter muscle and tongue;

(ii) in walruses: tongue;

(iii) in crocodiles: masseter, pterygoid and intercostal muscles;

(iv) in birds: muscles of the head (e.g. masseter and neck muscles);

(f) the digestion time must suffice to ensure adequate digestion of the tissue of these animals but must not exceed 60 minutes.

ANNEX IV

CHAPTER I

OFFICIAL RECOGNITION OF HOLDINGS OR A COMPARTMENT AS APPLYING CONTROLLED HOUSING CONDITIONS

The following requirements must be met by food business operators to obtain official recognition of holdings:

(a) the operator must have taken all practical precautions with regard to building construction and maintenance in order to prevent rodents, any other kind of mammals and carnivorous birds from having access to buildings where animals are kept;

(b) the operator must apply a pest-control programme, in particular for rodents, effectively to prevent infestation of pigs. The operator must keep records of the programme to the satisfaction of the competent authority;

(c) the operator must ensure that all feed has been obtained from a facility that produces feed in accordance with the principles described in Regulation (EC) No 183/2005 of the European Parliament and of the Council(1);

(d) the operator must store feed intended for

Trichinella

susceptible species in closed silos or other containers that are impenetrable to rodents. All other feed supplies must be heat-treated or produced and stored to the satisfaction of the competent authority;

(e) the operator must ensure that dead animals are collected, identified and transported without undue delay in accordance with Articles 21 and 22 of Regulation (EC) No 1069/2009 and with Annex VIII to Regulation (EU) No 142/2011;

(f) if a rubbish dump is located in the neighbourhood of the holding, the operator must inform the competent authority. Subsequently, the competent authority must assess the risks involved and decide whether the holding is to be recognised as applying controlled housing conditions;

(g) the operator must ensure that domestic swine are identified so that each animal can be traced back to the holding;

(h) the operator must ensure that domestic swine are only introduced onto the holding if they originate in and come from holdings officially recognised as applying controlled housing conditions;

(i) none of the domestic swine has access to outdoor facilities unless the operator can show by a risk analysis to the satisfaction of the competent authority that the time period, facilities and circumstances of outdoor access do not pose a danger for introduction of

Trichinella

in the holding;

(j) none of the swine for breeding and production, as defined in Article 2(2)(c) of Directive 64/432/EEC, has been unloaded after leaving the holding of origin at an assembly centre as defined in Article 2(2)(o) of Directive 64/432/EEC, unless the assembly centre meets the requirements of points (a) to (i) and all domestic swine being grouped for consignments at the assembly centre originate in and come from holdings officially recognised as applying controlled housing conditions or from officially recognised compartments.

Food business operators of holdings officially recognised as applying controlled housing conditions shall inform the competent authority where any of the requirements laid down in point A is no longer fulfilled or where any other change has occurred that might affect the status of the holding.

The competent authorities in Member States may only recognise a holding or a category of holdings provided that they have verified that the requirements laid down in point A are met.

CHAPTER II

REPORTING ON

TRICHINELLA

SITUATION

(a) The number of cases (imported and autochthonous) of

Trichinella

in humans, including epidemiological data shall be reported in accordance with Decision 2000/96/EC.

(b) The number of tests and the results of testing for

Trichinella

in domestic swine, wild boar, horses, game and any other susceptible animals shall be submitted in accordance with Annex IV to Directive 2003/99/EC. Data on domestic swine shall, at least, provide specific information related to:

(i) tests on animals raised under controlled housing conditions;

(ii) tests on breeding sows, boars and fattening pigs.
