Council Directive

of 21 December 1976

on the examination for trichinae (trichinella spiralis) upon importation from third countries of fresh meat derived from domestic swine

(77/96/EEC)

THE COUNCIL OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Economic Community,

Having regard to Council Directive 72/462/EEC of 12 December 1972 on health and veterinary inspection problems upon importation of bovine animals and swine and fresh meat from third countries [1], as last amended by Directive 75/379/EEC [2], and in particular Article 21 thereof,

Having regard to the proposal from the Commission,

Whereas in Directive 72/462/EEC the Council provided in Article 21 for the laying down of the method and procedures required for detecting the presence of trichinae in fresh pigmeat;

Whereas the application of Directive 72/462/EEC will not have the desired effects as long as disparities exist between the Member States as to the guarantees required in respect of the detection of trichinae upon importation of fresh meat from third countries; whereas it is therefore necessary to lay down Community arrangements in this field;

Whereas, in order to protect consumer health, it is necessary that fresh pigmeat be systematically subjected to an examination using methods recognized as effective, in order to eliminate meat containing trichinae;

Whereas when the examination is carried out in the exporting third country, it must be carried out in slaughterhouses which comply with certain conditions and which contain, in particular, a screening laboratory provided with suitable equipment;

Whereas in order to be able to distinguish the meat samples examined from those not examined it is necessary to provide for the affixing of a special mark to meat which has been examined with a negative result;

Whereas there should be a procedure establishing close and effective cooperation between the Commission and the Member States for assessing the advisability of permitting establishments in the third countries to carry out this examination or to work on the meat examined; whereas there should also be a procedure for bringing the technical provisions relating in particular to the examination methods, the requirements concerning the screening laboratories and the procedure for marking examined meat into line with technical progress and with experience acquired;

Whereas the Member States should be allowed to admit fresh meat which has not been screened for trichinae in the exporting third country, provided that this meat, undergoes treatment by freezing; which ensures that any trichinae which may be present are rendered harmless, either in the exporting third country, or in the Member State for which the meat is intended; whereas this treatment must nevertheless be carried out according to certain well defined procedures and establishments fulfilling certain conditions,

HAS ADOPTED THIS DIRECTIVE:

Article 1

ANNEX I

METHODS OF EXAMINATION FOR TRICHINAE

I. TRICHINOSCOPIC EXAMINATION

(a) Apparatus

An incandescent lamp trichinoscope with 50 × and 80 to 100 × magnification.

A pressure glass consisting of two glass plates — one of which is divided into equal fields — small curved scissors, small forceps, a knife for cutting specimens, small numbered containers for storing the specimens separately, a dropping pipette, a glass of acetic acid and a glass of potassium hydroxide solution for brightening any calcifications or softening dried meat.

(b) Taking of specimens

In the case of whole carcases, at least one specimen of the size of a hazelnut is to be taken from both diaphragm pillars at the transition of the sinewy part.

If there is only one diaphragm pillar, one specimen the size of two hazelnuts is to be taken. In the absence of both diaphragm pillars, two specimens approximately the size of a hazelnut are to be taken from the rib part or the breastbone part of the diaphragm or, as the case may be, from the lingual muscle or the jaw muscle or from the abdominal muscles.

For pieces of meat, from each piece take three samples of skeletal muscle, containing little fat, if possible the size of a hazelnut, and taken from different points, where possible near to bones or tendons.

(c) Method

If both diaphragm pillars are present the trichinae inspector must cut, from each of the above specimens taken from a whole carcase, seven pieces the size of an oat-kernel making 14 in all; if only one diaphragm pillar is present, 14 pieces, from different places and if possible from the transition to the sinewy part; he must then compress them between the glass plates in such a way that normal print can be clearly read through the slide preparation. If the flesh of the specimens to be examined is dry and old, the preparations must be softened in a mixture of one part potassium hydroxide solution to about two parts water for 10 to 20 minutes before pressing.

If, in the case of whole carcases, specimens have to be taken from the rib part or the breastbone part of the diaphragm, the lingual muscle or jaw muscle or the abdominal muscles, then 14 pieces the size of an oat-kernal are to be cut from each specimen, i.e. a total of 28.

From each of the samples taken from pieces of meat, the trichinae inspector must cut four pieces the size of an oat-kernal, making 12 pieces in all.

The trichinoscopic examination must be carried out in such a manner that each preparation is scanned slowly and carefully. If the trichinoscopic examination reveals suspect areas, the nature of which cannot be definitely ascertained even with the most powerful magnification of the trichinoscope, these must be checked by microscope.

The microscopic examination should be carried out in such a manner that each preparation is scanned slowly and carefully at a magnification of 30 to 40 ×.

In the case of an uncertain result, the examination must be continued on a further number of specimens and slide preparations, if necessary with the aid of higher magnifications, until the information required is obtained. The trichinoscopic examination must be carried out for at least three minutes.

The trichinoscopic examination must be carried out for at least six minutes in the case of substitute specimens taken from the rib part or breastbone part of the diaphragm pillars, the lingual muscle or the jaw muscle or the abdominal muscles.

The minimum time fixed for the examination does not include the time necessary for sample-taking and for making the preparations.

As a general rule, the trichinoscopic examiner should not inspect more than 840 pieces a day, though by way of exception he may inspect up to 1050.

II. THE ARTIFICIAL DIGESTION METHOD

(a) Apparatus and material

- knife for taking samples,

- small numbered containers, with closures, for storing samples, if necessary until repetition of the examinations,

- incubator,

- 2 to 3 litre glass funnel with stand, a connecting hose in rubber, clamps for fastening the connecting hose,

- a plastic sieve (approximately 18 cm in diameter, and approximately 1 mm mesh),

- gauze,

- a small tapering tube with a sealed end,

- a glass block dish,

- a meat mincer,

- a stereo-microscope,

- digestive liquid made up as follows:

10 g of pepsin (1200 u/g), 5 ml HCl (at least 37 %) made up to a litre with tap water.

(b) Taking of specimens

1. In the case of whole carcases a sample of at least 20 g to be taken from a diaphragm pillar at the transition to the sinewy part. In the absence of diaphragm pillars a specimen of at least 20 g to be taken from the rib part or the breastbone part of the diaphragm or from the lingual muscle or the jaw muscle or the abdominal muscles.

2. For pieces of meat, a sample of at least 20 g of skeletal muscle to be taken, containing little fat and where possible near to bones or tendons.

(c) Method

For the examination of a collective specimen from 10 pigs, a 10 g specimen shall be prepared from each individual 20 g sample. The remaining 10 g shall be kept for additional single-specimen examination should this be necessary.

10 specimens, each weighing 10 g, shall be combined into a collective specimen; it shall be minced in a meat mincer (with 2 mm perforations) and placed loosely in a sieve lined with a layer of gauze. The sieve shall then be placed in a funnel connected by a length of rubber hose to a small tapered tube with a sealed end; the funnel shall be filled from the edge with digestive liquid until the matter for analysis is completely covered. The proportion of matter for analysis to digestive liquid must be approximately 1:20 to 1:30.

After 18 to 20 hours of incubation at 37 to 39 °C, the small tapered tube shall be disconnected and removed. After carefully drawing off the supernatant liquid, the sediment present in the tip of the tube is to be carefully rinsed in a dish. Then to be examined for the presence of trichinae with a stereo-microscope at 20 to 40 × magnification.

In the case of a positive or doubtful result from the examination of a collective specimen, the remaining single specimens to be examined individually after addition of a further 20 g from each pig, or in the case of pieces of meat, the addition of 20 g taken from each piece, according to (b) above.

III. METHOD USING THE ARTIFICIAL DIGESTION OF COLLECTIVE SAMPLES

(a) Apparatus and reagents

- knife and tweezers for collecting specimens,

- meat mincer with 2 to 3 mm diameter perforations,

- a 3 ml Erlenmeyer flask with a rubber or cotton-wool plug,

- a conical separation funnel of 2000 ml capacity,

- an ordinary A-base stand of approximately 28 cm length with an 80 cm stem,

- a ring, diameter approximately 10 to 11 cm which can be fixed to the stand,

- a clamp with a flat vice (23 × 40 mm) which can be attached to the stand by means of a double coupling,

- an Endecott sieve number 80 (mesh fineness 177) with an external diameter of 11 cm fitted with brass or stainless steel mesh,

- a plastic funnel with an internal diameter of not less than 12 cm,

- an ordinary dissection microscope (magnification 40 ×) fitted with its ordinary lamp, or a standard binocular microscope (magnification 40 ×),

- a trichinoscope with horizontal table for the compressor,

- when using the trichinoscope: a larvae counting basin of the same outer shape as the compressor with a volume of approximately 60 to 65 cc. The larvae counting basin may be described as follows:

The shape of the basin consists of a 23 cm long glass plate being of the same thickness as that of a single plate in a common compressor. The width, however, is slightly less, e.g. 4·5 cm in order to provide for the fixation of a glass plate, 2 mm thick, 1·8 cm high, and 17·5 cm long, on both of the long sides of the bottom plate.

The basin is closed at the ends by two glass plates fixed directly onto the bottom plate, and which are 5 cm long, 1 cm high, and 2 mm thick. The height of the basin, measured from inside, will thus be about 1 cm.

The plates are glued together with ordinary glass adhesive. Approximately 2·8 cm of the bottom plate is left free at both ends for protection purposes, and for easy handling of the filled basin.

The volume of the basin is approximately 60 to 65 cc in total,

- when using the microscope a number of 9 cm diameter Petri dishes are needed,

- a speedmarker for marking out in the bottom of the Petri dish the 1 cm square examination areas,

- a number of 10 litre bins to be used when applying formol treatment to the apparatus, and for the remaining digestive juice in the case of positive results,

- concentrated (37 %) hydrochloric acid,

- 30000 units per gram of "Merck" powdered pepsin, or pepsin with known strength from another firm,

- one or two trays which can hold 100 samples or approximately 2 g of meat.

(b) Collection of specimens

1. In the case of whole carcases a specimen to be taken of approximately 2 g from a pillar of the diaphragm at the transition to the sinewy part. In the absence of diaphragm pillars a specimen of the same size to be taken from the rib part or the breastbone part of the diaphragm, from the lingual muscle or the jaw muscle or the abdominal muscles.

2. For cuts of meat, a sample of approximately 2 g of skeletal muscle to be taken, containing little fat and where possible near to bones or tendons.

(c) Method

Approximately 1 g of sample shall be taken from each of the 100 individual samples from the pigs. The pooled sample is put once through the mincer.

The minced meat shall be placed in the 3 litre Erlenmeyer flask together with 7 g of pepsin, approximately 2 litres of tap water heated to about 37 to 40 °C, and 25 ml of concentrated hydrochloric acid. The mixture shall be shaken to dissolve the pepsin.

The pH of the solution will be about 1·5 to 2.

- For digestion the Erlenmeyer flask shall be incubated at 37 °C for approximately four hours. The flask shall be regularly shaken during the time of incubation, e.g. once or twice every hour.

- The digested solution shall be filtered through the sieve into the conical 2 litre separation funnel and left undisturbed on the stand for at least one hour.

- A total volume of approximately 45 cc shall be run out of the funnel and divided between three Petri dishes, the bottoms of which shall be marked out in 1 cm squares, with 15 ml in each dish.

- Each Petri dish shall be minutely examined for larval trichinae under the microscope (around 40 × magnification).

- Where larvae counting basins are employed, the 45 cc shall, be distributed between two larvae counting basins and examined under the trichinoscope.

The larvae appear as identifable organisms in the deposit, and often, when the water is lukewarm, rolling and unrolling movements of the "spiral" may be observed.

If an insufficiently transparent sediment forms, it shall be clarified by rinsing. The final sample of 45 ml is poured into a test tube and allowed to settle for 15 minutes. The supernatant liquid shall then be carefully removed by suction and the sediment placed into suspension in about 45 ml of tap water.

After a further settling period of 15 minutes, the supernatant liquid shall again be carefully removed by suction and the sediment carefully rinsed in about 20 ml of tap water in a Petri dish, and examined.

In the case of a positive or doubtful result from analysis of a collective specimen, the remaining single specimens to be analyzed individually after addition of a further 20 g from each pig, or, in the case of pieces of meat, the addition of 20 g taken from each piece, in accordance with (b) above.
