(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 ofbovine 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,
Whereasin Directive 72/462/EEC the Council provided in Article 21
for the laying down of the method and proceduresrequired fordetecting the presence of trichinae in fresh pigmeat;
Whereasthe application of Directive 72/462/EEC will not have the
desired effects as long as disparities exist between the Member Statesasto the guaranteesrequired in res pect of the detection of trichinaeupon 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 aseffective, in order to eliminate meat containing trichinae;
Whereaswhen the examination iscarried out in the exporting third
country, it must be carried out in slaughterhouses which comply with
certain conditionsand which contain, in particular, a s creening labora-tory 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 aspecial 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 asses-sing the advisability of permitting establishments in the third countriesto carry out thisexamination or to work on the meat examined;whereas there should also be a procedure for bringing the technicalprovisions relating in particular to the examination methods, the
requirementsconcerning the s creening laboratoriesand the procedure
for marking examined meat into line with technical progress and withexperience acquired;
Whereas the Member States should be allowed to admit fresh meat
which hasnot been s creened for trichinae in the exporting thirdcountry, provided that thismeat, undergoestreatment by freezing;which ensures that any trichinae which may be present are renderedharmless, either in the exporting third country, or in the Member State
for which the meat isintended; whereasthistreatment mus t neverthe-
less be carried out according to certain well defined procedures andestablishments fulfilling certain conditions,1977L0096 — EN — 28.04.1989 — 006.001 — 2

ANNEX I
METHODSOFEXAMINATIONFORTRICHINAE
I. TRICHINOSCOPIC EXAMINATION
(a)Apparatus
An incandescent lamp trichinoscope with 50 × and 80 to 100 × magni-
fication.
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)Takingofspecimens
In the case of whole carcases, at least one specimen of the size of a
hazelnut isto be taken from both diaphragm pillarsat the trans ition
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
piecesthe s ize 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
piecesin all.
The trichinoscopic examination must be carried out in such a manner
that each preparation is scanned slowly and carefully. If the trichino-
scopic 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 magnifica-
tion 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.1977L0096 — EN — 28.04.1989 — 006.001 — 6
▼B
The minimum time fixed for the examination doesnot 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 piecesa day, though by way of exception he may ins pect up
to 1 050.
II. THE ARTIFICIAL DIGESTION METHOD
(a)Apparatusandmaterial
— 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 approxi-
mately 1 mm mesh),
— gauze,— a small tapering tube with a sealed end,— a glass block dish,— a meat mincer,
— a stereo-microscope (magnification 15 to 40 ×) with a suitable light
source,
— digestive liquid made up as follows:
10 g of pepsin (80 u/g FIP: Fédération internationale de phar-
macie), 5 ml HCl (at least 37 %) made up to a litre with tap-water.
(b)Takingofspecimens
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 examina-
tion 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 perfora-
tions) 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 diges-
tive liquid must be approximately 1:20 to 1:30.
After 18 to 20 hoursof incubation at 37 to 39 ºC, the s mall 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.1977L0096 — EN — 28.04.1989 — 006.001 — 7

the stand,
— a clamp with a flat vice (23 × 40 mm) which can be attached to the
stand by means of a double coupling,
— a sieve (mesh size 177 microns) with an external diameter of 11 cm
fitted with brass or stainless steel mesh,
— a funnel with an internal diameter of not less than 12 cm,
— 100 ml glass measuring cylinders,
— a stereo-microscope (magnification 15 to 40 ×) with a suitable light
source, or a trichinoscope with horizontal table for the compressor
with suitable light source,
— when using the trichinoscope: a larval counting basin is used which
may be described as follows:
the larval counting basin is made from 3 mm thick acrylic plates,
asfollows :
(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 endss hould be
inserted between the sides, thus forming a basin with two
small handles in both ends. The upper side of the bottom
should be raised 7 to 9 mm from the base of the frame formed
by the sides and the ends. The parts should be fixed by using
glue appropriate for the material,
— a number of 9 cm diameter Petri dishes (when using stereo-micro-
scope) marked on their undersides into 10 × 10 mm square
examination areas using a pointed instrument,
— a number of 10 litre binsto be us ed when applying decontamina-
tion, such as formol treatment, to the apparatus and for the
remaining digestive juice in the case of positive results,
— concentrated (37 %) hydrochloric acid,
— pepsin strength: 1: 10 000 NF (US National Formulary)
corresponding to 1: 12 500 BP (British Pharmacopoea)
corresponding to 2 000 FIP (Fédération internationale de phar-
macie),
— a number of trayswhich can hold 50 s amplesof approximately 2 g
each,
— a balance accurate to 0,1 g.
(b)Collectionofspecimens
1. In the case of whole carcases, a specimen to be taken of approxi-
mately 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 of 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
1. (i)Complete pools (100 samples at a time)
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-water1977L0096 — EN — 28.04.1989 — 006.001 — 8
▼M3
heated to about 40 to 41 ºC and 25 ml of concentrated hydro-
chloric 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 40
to 41 ºC for approximately four hours. The flask shall be
regularly shaken during the time of incubation, at least
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 ml should be run off
into a measuring cylinder and divided between three Petri
dishes, the bottoms of which should be marked off into
squares, with 15 ml in each dish.
— Each Petri dish shall be minutely examined for larval
trichinae under the stereo-microscope.
— Where larval counting basins are employed, the 45 ml shall
be distributed between two larval counting basins and
examined under the trichinoscope.
The larvae appear as identifiable organisms in the deposit
and often, when the water islukewarm, rolling and unrol-
ling movements of the ‘spiral’ may be observed.
— Digests should be examined as soon as they are ready.
Under no circumstances should examination be postponed
until the following day.
If the digests are unclear or not examined within 30 minutes
of their preparation, they should be clarified as follows. The
final sample of 45 ml is poured into a measuring cylinder
and allowed to stand for 10 minutes. At the end of this
time, 30 ml of supernatant fluid is removed by suction and
the remaining 15 ml ismade 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. The measuring cylinder should be washed
with 10 ml of tap-water and these washings should be added
to the sample in the Petri dish or larval counting basin for
examination.
(ii)Pools of less than 100 samples
Up to 15 single samples could be added to a total pool of 100
samples and be examined together with these samples. If more
than 15 samples and less than 100 samples are examined, thedigestion fluid should be reduced proportionately.
2. In the case of a positive or doubtful result following the examina-
tion of a collective sample, a further 20 g sample should be taken
from each pig in accordance with (b) above. The 20 g samples from
five pigs should be pooled and examined by the method described
above. In thisway s amplesfrom 20 groupsof five pigswill be
examined. When trichinellae are detected in a pooled sample from
five pigs, further 20 g samples should be collected from the indivi-
dual pigs in the group and each should separately be examined
using the method described above.

(c)Method
1.Digestion procedure
(i)Complete pools (100 samples at a time)
— The Stomacher Lab-blender 3 500 should be fitted with a
double plastic bag and the temperature control set at 40 to
41 ºC
— One and a half litresof water preheated to about 32 to 35 ºC
ispoured into the inner plas tic bag and the water heated to
40 to 41 ºC.
— 25 ml of 17,5 % hydrochloric acid isthen added to the
water in the Stomacher.
— 100 samples of approximately 1 g each (at 25 to 30 ºC)
taken from each of the individual samples, in accordance
with (b), are then added.
— 6 g pepsin is finally added. This order of addition should be
strictly adhered to in order to avoid decomposition of the
pepsin.
— The Stomacher isthen allowed to pound the content of the
bag for 25 minutes.
— The pastic bag is then removed from the Stomacher and the
digestion fluid is filtered through the sieve into a 3 litre
beaker.1977L0096 — EN — 28.04.1989 — 006.001 — 10
▼M3
— The plastic bag is washed with approximately 100 ml of
water, which is then used to rinse the sieve and finally
added to the filtrate in the beaker.
Up to 15 single samples could be added to a total pool of 100
samples and be examined together with these samples.
(ii)Smaller pools less than 100 samples
— The Stomacher Lab-blender 3 500 should be fitted with a
double plastic bag and the temperature control set at 40 to
41 ºC.
— A digestion fluid is prepared by mixing about one and a
half litresof 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 ºC. This order of addition should be strictly
adhered to in order to avoid decomposition of the pepsin.
— Of the digestion fluid, a volume corresponding to 15 ml per
gram of sample is measured (e.g. for 30 samples the volume
required is30 × 15 ml or 450 ml) and trans ferred to the
inner of the two plastic bags together with the meat samples
of approximately 1 g (at 25 to 30 ºC) taken from each of the
individual samples in accordance with (b).
— Water at a temperature of approximately 41 ºC ispoured
into the outer bag to a total volume in the two bagsof one
and a half litres.
— The Stomacher isthen allowed to pound the content of the
bag for 25 minutes.
— The plastic bag is then removed from the Stomacher and the
digestion fluid is filtered through the sieve into a 3 litre
beaker.
— The plastic bag is washed with approximately 100 ml of
water, which is then used to rinse the sieve and finally
added to the filtrate in the beaker.
2.Recovery of larvae by sedimentation
— Ice (300 to 400 g of ice flakes, scaly ice or crushed ice) is
added to the digestion fluid, bringing 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 1 (ii)), the amount of ice
should be reduced correspondingly.
— The chilled digestion fluid is transferred to a 2 litre separation
funnel, equipped with a vibrator in an extra clamp.
— Sedimentation for 30 minutes, during which time the sedimenta-
tion funnel isvibrated intermittently, i.e. one minute vibration
followed by 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 should be withdrawn by
suction, leaving a volume of 15 ml to be examined for the
presence of larvae.
— For suction, a disposable syringe can be used, equipped with a
plastic tube.
The length of the tube should be such that 15 ml will remain in
the measuring cylinder when the flanges of the syringe rest on
the cylinder'srim.
— The remaining 15 ml ispoured into a larval counting bas in or
two Petri dishes and examined using a trichinoscope or stereo-
microscope respectively.
— Digests should be examined as soon as they are ready. Under no
circumstances should examination be postponed until the
following day.
If the digests are unclear, or are not examined within 30 minutes
of their preparation, they should be clarified as follows. The
final sample of 60 ml is poured into a measuring cylinder and
allowed to stand for 10 minutes. At the end of this time, 45 ml
of supernatant fluid is removed by suction and the remaining
15 ml ismade 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. The
measuring cylinder should be washed with 10 ml of tap-water1977L0096 — EN — 28.04.1989 — 006.001 — 11
▼M3
and these washings should be added to the sample in the Petri
dish or the larval counting basin for examination.
3. In the case of a positive or doubtful result, following the examina-
tion of a collective sample, a further 20 g sample should be taken
from each pig in accordance with (b) above. The 20 g samples from
five pigs should be pooled and examined by the method described
above. In thisway, s amplesfrom 20 groupsof five pigswill be
examined. When trichinellae are detected in a pooled sample from
five pigs, further 20 g samples should be collected from the indivi-
dual pigs in the group and each should separately be examined
using the method described above.
V. THE MECHANICALLY ASSISTED POOLED SAMPLE DIGESTION
METHOD/ ‘ON FILTER ISOLATION’ TECHNIQUE
(a)Apparatusandreagents
Those indicated in method IV (a).Supplementary equipment to the abovementioned:
— 1 litre Gelman funnel, complete with filter holder (diameter
45 mm),
— filter discs; the filter discs consist of:
a circular stainless steel mesh with an aperture of 35 microns (the
diameter of the disc should be 45 mm),
two rubber ringsmade of 1 mm thick rubber (the external diameter
should be 45 mm and the internal diameter 38 mm),
the circular mesh is placed between the two rubber rings and
bonded to them using a two-component glue suitable for the two
materials,
— an Erlenmeyer flask with a capacity of 3 litres and fitted with a
side tube for suction,
— a filter pump,
— plastic bags with a capacity of at least 80 ml,
— equipment for sealing the plastic bags,— rennilase, strength 1: 150 000 soxhlet units per gram.
(b)Collectionofspecimens
See method IV (b).
(c)Method
1.Digestion procedure
(i)Complete pools (100 samples at a time)
See method IV (c) (1) (i).
(ii)Smaller pools less than 100 samples
See method IV (c) (1) (ii).
2.Recovery of larvae by filtration
— Ice (300 to 400 g of ice flakes, scaly ice or crushed ice) is
added to the digestion fluid, bringing its volume up to about 2
litres.
In the case of smaller pools, the amount of ice should be
reduced correspondingly.
— The digestion fluid is then stirred until the ice has melted. The
chilled digestion fluid is then left for at least three minutes to let
the larvae coil.
— The Gelman funnel, fitted with a filter holder and filter disc, is
mounted on the Erlenymeyer flask connected to a filter pump.
— The digestion fluid is poured into the Gelman funnel and
filtered. Towards the end of filtration, the passage of the diges-
tion fluid through the filter can be assisted by applying suction
with the filter pump. Suction should cease before the filter
becomesdry, i.e. when 2 to 5 ml of fluid are left in the funnel.
— When 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 solution of rennilase
ismade by adding 2 g of rennilas e to 100 ml of tap-water.
— The plastic bag is sealed twice and placed in the Stomacher
between the inner and outer bag.1977L0096 — EN — 28.04.1989 — 006.001 — 12
▼M3
— The Stomacher isallowed to pound for three minutes , e.g. while
it isworking on a complete or incomplete pool.
— 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 isthen added to the larval counting
basin for examination by trichinoscope or to the Petri dish for
examination by stereo-microscope.
— Digests should be examined as soon as they are ready. Under no
circumstances should examination be postponed until the
following day.
NoteFilter discs should never be used when not completely clean.
Unclean discs should never be allowed to dry out.
Filter discs can be cleaned by leaving them in rennilase solution
overnight. Before use, they should be washed in fresh rennilase
solution using the Stomacher.
3. In the case of a positive or doubtful result, following the examina-
tion of a collective sample, a further 20 g sample should be taken
from each pig in accordance with (b) above. The 20 g samples from
five pigs should be pooled and examined by the method described
above. In thisway, s amplesfrom 20 groupsof five pigswill be
examined. When trichinellae are detected in a pooled sample from
five pigs, further 20 g samples should be collected from the indivi-
dual pigs in the group and each should separately be examined
using the method described above.

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
1. (i)Complete pools (100 samples at a time)
— 100 samples of approximately 1 g each, taken from each of
the individual samples in accordance with (b), are chopped
in the Moulinette blender. The blender should be operated
three to four timesfor approximately one s econd each time.
— The chopped meat istrans ferred to a 3 litre beaker and
sprinkled with 10 g of pepsin. 2 litres of tap-water,
preheated to 46 to 48 ºC, ispoured into the beaker, together
with 16 ml of hydrochloric acid.
— The mincing insert of the Moulinette blender is immersed
repeatedly in the digestion fluid in the beaker to remove
any meat still adhering.
— The stirring rod is placed in the beaker and the beaker is
covered with aluminium foil.
— The beaker isplaced on the preheated heating plate of the
magnetic stirrer and the stirring process started. Before
starting the stirring process, the magnetic stirrer should be
adjusted so that it maintains a constant temperature of 44
to 46 ºC throughout the period of operation. During the stir-
ring process, the digestion fluid should rotate at a

— The digestion fluid is stirred for 30 minutes, at the end of
which the stirrer is switched off and the digestion fluid is
poured through the sieve into the sedimentation funnel.
— The digestion fluid is allowed to stand in the funnel for 30
minutes.
— After 30 minutes, a 40 ml sample of digestion fluid is
quickly run off into the measuring cylinder or centrifuge
tube.
— The 40 ml sample is allowed to stand for 10 minutes, at the
end of which time 30 ml of supernatant is withdrawn by
suction, leaving a volume of 10 ml.
— The remaining 10 ml sample of sediment is poured into a
larval counting basin or Petri dish.
— Then the cylinder or centrifuge tube isrins ed with about
10 ml of tap-water which hasto be added to the s ample in
the larval counting basin or Petri dish. Subsequently, the
sample is examined by trichinoscope or stereomicroscope
respectively.
— Digests should be examined as soon as they are ready.
Under no circumstances should examination be postponed
until the following day.
If the digests are not examined within 30 minutes of their
preparation, they should be clarified as follows. The final
sample of about 40 ml is poured into a measuring cylinder
and allowed to stand for 10 minutes, after which time 30 mlof the supernatant fluid is removed leaving a volume of
10 ml. Thisvolume ismade 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 10 ml for examination in a Petri dish or larval counting1977L0096 — EN — 28.04.1989 — 006.001 — 14
▼M3
basin. The measuring cylinder should be washed with 10 ml
of tap-water and these washings should be 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 should be poured into a measuring cylinder and
made up to 40 ml with tap-water and then the above proce-
dure should be followed.
(ii)Pools of less than 100 samples
When needed, up to 15 samples of 1 g each may be added to a
total pool of 100 samples and examined together with these
samples according to (c) (1) (i). More than 15 samples should
be examined as a complete pool. For pools up to 50 samples,
the digestion fluid may be reduced to 1 litre.
2. In the case of a positive or doubtful result following the examina-
tion of a collective sample, a further 20 g sample should be taken
from each pig in accordance with (b) above. The 20 g samples from
five pigs should be pooled and examined by the method described
above. In thisway s amplesfrom 20 groupsof five pigswill be
examined. When trichinellae are detected in a pooled sample from
five pigs, further 20 g samples should be collected from the indivi-
dual pigs in the group and each should separately be examined
using the method described above.

and lead the tube to the waste bin.1977L0096 — EN — 28.04.1989 — 006.001 — 15
▼M5
▼M5
— When the blender is switched on, the heat-up will start.
— Before start, the bottom valve, located below the reaction
chamber, should be opened and closed.
— Up to 35 samples of approximately 1 g each (at 25 to 30º C)
taken from each of the individual samples, in accordance with
point b, are then added. Make sure that larger pieces of tendons
are removed asthismay clot the membrane filter.
— Pour water to the edge of a liquid chamber connected to the
blender (approximately 400 ml).
— Pour about 30 ml hydrochloric acid (8,5 %) to the edge of the
smaller, connected liquid chamber.
— Place a membrane filter under the coarse filter in the filter
holder in the filter insert.
— 5 g of pepsin is added last. The order of addition should be
strictly adhered to in order to avoid decomposition of the
pepsin.
— Close the lids to the reaction- and liquid chambers.
— Select the period of digestion. Short digestion period (5
minutes) for pigs at normal age of slaughtering and extended
digestion time (8 minutes) for other samples.
— The automatic dispensing starts when the start button on the
blender isactivated and diges tion with following filtration will
proceed automatically. After 10 to 13 minutesthe proces sis
completed and stops automatically.
— The lid to the reaction chamber isopened once it ischecked that
the chamber isemptied. If there isfoam or remainsof diges tion
liquid in the chamber repeat the procedure according to point 4.
2.Recovery of larvae
— Dismount the filter holder and transfer the membrane filter to a
slide or a Petri dish.
— The membrane filter isexamined by meansof a micros cope or a
trichinoscope.
3.Cleaning of equipment
— In the case of a positive result, fill the reaction chamber in the
blender /twothirdwith boiling water. Ordinary tap-water ispoured into
the connecting liquid chamber until the lower level sensor is
covered. The automatic cleaning programme isthen carried
out. De-contaminate the filter-holder together with the
remaining equipment, for example by meansof formal treat-
ment.
— After the day'swork fill the liquid chamber in the blender with
water and carry out a standard programme.
4.Method to be used when digestion is incomplete and filtration
cannot therefore be carried out
When the automatic process in the blender is carried out according
to point 1, open the lid to the reaction chamber and check whether
there isfoam or liquid remaining in the chamber. It thisisthe cas e,
carry out the following procedure:
— Close the bottom valve below the reaction chamber.
— Dismount the filter holder and transfer the membrane filter to a
slide or a Petri dish.
— Put a new membrane filter in the filter holder and mount the
filter holder.
— Fill water into the liquid chamber in the blender until the lower
level-sensor is covered.
— Carry out the automatic cleaning programme.
— After the cleaning programme hasbeen completed open the lid
to the reaction chamber and check for liquid remains.
— If the chamber is empty, dismount the filter holder and transfer
the membrane filter with a tweezer to a slide or a Petri dish.
— The two membrane filtersare examined according to point 2. If
the filterscannot be examined repeat the entire diges tion
process with extended digestion time according to point 1.
5. In the case of a positive or doubtful result, following the result of a
collective sample, a further 20 g sample should be taken from each
pig in accordance with point b above. These samples shall be inves-
tigated individually according to the abovementioned method.1977L0096 — EN — 28.04.1989 — 006.001 — 16
