In addition to the testing referred to in points 2 to 4, Member States may on a voluntary basis decide to test other bovine animals on their territory, in particular where those animals originate from countries with indigenous BSE, have consumed potentially contaminated feedingstuffs or were born or derived from BSE infected dams.
6. Measures following testing
6.1. Where an animal slaughtered for human consumption is tested for BSE, the health marking provided for in Chapter XI of Annex I to Directive 64/433/EEC shall not be carried out on the carcase of that animal until a negative result to the rapid test has been obtained.
6.2. Member States may derogate from the provisions of point 6.1 where an official system is in place in the slaughterhouse ensuring that no parts of examined animals bearing the health mark leave the slaughterhouse until a negative result to the rapid test has been obtained.
6.3. All parts of the body of an animal tested for BSE including the hide shall be retained under official control until a negative result to the rapid test has been obtained, unless they are destroyed in accordance with Annex V, point 3 or 4.
6.4. All parts of the body of an animal found positive to the rapid test including the hide shall be destroyed in accordance with Annex V, point 3 or 4, apart from material to be retained in conjunction with the records provided for in Chapter B, Section III.
6.5. Where an animal slaughtered for human consumption is found positive to the rapid test, at least the carcase immediately preceding the test-positive carcase and two carcases immediately following the test-positive carcase on the same slaughter line shall be destroyed in accordance with point 6.4, in addition to the test-positive carcase.
6.6. Member States may derogate from the provisions of point 6.5 where a system is in place in the slaughterhouse preventing contamination between carcases.
II. MONITORING IN OVINE AND CAPRINE ANIMALS
1. General
Monitoring in ovine and caprine animals shall be carried out in accordance with the laboratory methods laid down in Annex X, Chapter C, point 3.2(b).
2. Monitoring in animals slaughtered for human consumption
Animals over 18 months of age slaughtered for human consumption shall be tested in accordance with the sample size indicated in the table. The sampling shall be representative for each region and season. The sample selection shall be designed with a view to avoid the over-representation of any group as regards the origin, species, age, breed, production type or any other characteristic. The age of the animals shall be estimated based on dentition, obvious signs of maturity or other reliable information. Multiple sampling in the same flock shall be avoided, where possible.
>TABLE>
3. Monitoring in animals not slaughtered for human consumption
Animals over 18 months of age which have died or been killed, but which were not:
- killed in the framework of an epidemic, such as foot-and-mouth disease,
- slaughtered for human consumption,
shall be tested in accordance with the sample size indicated in the table. The sampling shall be representative for each region and season. The sample selection shall be designed with a view to avoid the over-representation of any group as regards the origin, species, age, breed, production type or any other characteristic. The age of the animal shall be estimated based on dentition, obvious signs of maturity or other reliable information. Multiple sampling in the same flock shall be avoided, where possible.
>TABLE>
4. Monitoring in Member States with a small ovine and caprine population
Member States, where the total number of ovine and caprine animals over 18 months of age is 500000 or less may, by way of derogation from the sampling foreseen in points 2 and 3, decide to monitor the following combined subpopulation:
(a) animals over 18 months of age which have died or been killed, but which were not:
- killed in the framework of an epidemic, such as foot-and-mouth disease,
- slaughtered for human consumption ("dead animals"); and
(b) animals over 18 months of age whose appearance suggests a chronic wasting condition ("chronic wasting animals").
The number of samples tested annually in each Member State from the above combined subpopulation shall not be less than the sample size indicated in the table.
The sampling shall be representative for each region and season. The sample selection shall be designed with a view to avoid the over-representation of any group as regards the origin, species, age, breed, production type or any other characteristic. Where dead animals are sampled, the age of the animal shall be estimated based on dentition, obvious signs of maturity or other reliable information. Where chronic wasting animals are sampled, only animals inspected by an official veterinarian and for which the age and clinical symptoms are well documented shall be selected for sampling. Multiple sampling in the same flock shall be avoided, where possible.
>TABLE>
5. Monitoring in other animals
In addition to the monitoring programmes set out in points 2 to 4, Member States may on a voluntary basis carry out monitoring in other animals, in particular:
- animals used for dairy production,
- animals originating from countries with indigenous TSEs,
- animals which have consumed potentially contaminated feedingstuffs,
- animals born or derived from TSE infected dams,
- animals from flocks infected with TSE.
6. Measures following testing of ovine and caprine animals
All parts of the body of a tested animal including the hide shall be retained under official control until a negative result to the rapid test has been obtained, unless they are destroyed in accordance with Annex V, point 3 or 4.
All parts of the body of an animal found positive to the rapid test including the hide shall be destroyed in accordance with Annex V, point 3 or 4, apart from material to be retained in conjunction with the records provided for in Chapter B, section III.

"CHAPTER C
Sampling and laboratory testing
1. Sampling
Any samples intended to be examined for the presence of a TSE shall be collected using the methods and protocols laid down in the latest edition of the Manual of standards for diagnostic tests and vaccines of the International Office for Epizooties (IOE/OIE) (hereinafter referred to as 'the Manual'). In the absence of such methods and protocols, the samples shall be collected in a manner appropriate for the correct application of tests. The samples shall be correctly marked as to the identity of the sampled animal.
2. Laboratories
Any laboratory examination for TSE shall be carried out in laboratories approved for that purpose.
3. Methods and protocols
3.1. Laboratory testing for the presence of BSE in bovine animals
(a) Suspect cases
Tissues from bovine animals sent for laboratory testing pursuant to the provisions of Article 12(2) shall be subject to a histopathological examination as laid down in the latest edition of the Manual, except where the material is autolysed. Where the result of the histopathological examination is inconclusive or negative or where the material is autolysed, the tissues shall be subjected to an examination by one of the other diagnostic methods laid down in the Manual (immunocytochemistry, immuno-blotting or demonstration of characteristic fibrils by electron microscopy). However, rapid tests cannot be used for this purpose.
If the result of one of the above examinations is positive, the animals shall be regarded a positive BSE case.
(b) BSE monitoring
Tissues from bovine animals sent for laboratory testing pursuant to the provisions of Annex III, Chapter A, Section I (Monitoring in bovine animals) shall be examined by a rapid test.
When the result of the rapid test is inconclusive or positive, the tissues shall immediately be subject to confirmatory examinations in an official laboratory. The confirmatory examination shall start by a histopathological examination of the brainstem as laid down in the latest edition of the Manual, except where the material is autolysed or otherwise not suitable for examination by histopathology. Where the result of the histopathological examination is inconclusive or negative or where the material is autolysed, the tissues shall be subjected to an examination by one of the other diagnostic methods mentioned under (a).
An animal shall be regarded a positive BSE case if the result of the rapid test is positive or inconclusive, and
- the result of the subsequent histopathological examination is positive, or
- the result of another diagnostic method mentioned under (a) is positive.
3.2. Laboratory testing for the presence of scrapie in ovine and caprine animals
(a) Suspect cases
Tissues from ovine and caprine animals sent for laboratory testing pursuant to the provisions of Article 12(2) shall be subject to a histopathological examination as laid down in the latest edition of the Manual, except where the material is autolysed. Where the result of the histopathological examination is inconclusive or negative or where the material is autolysed, the tissues shall be subjected to an examination by immunocytochemistry or immuno-blotting, as laid down in the Manual. However, rapid tests cannot be used for this purpose.
If the result of one of the above examinations is positive, the animal shall be regarded a positive scrapie case.
(b) Scrapie monitoring
Tissues from ovine and caprine animals sent for laboratory testing pursuant to the provisions of Annex III, Chapter A, Section II (Monitoring in ovine and caprine animals) shall be examined by a rapid test.
When the result of the rapid test is inconclusive or positive, the brainstem shall immediately be sent to an official laboratory for confirmatory examinations by immunocytochemistry or immuno-blotting, as referred to under (a).
An animal shall be regarded a positive scrapie case if the result of the confirmatory examination is positive.
3.3. Laboratory testing for the presence of TSEs other than those referred to in points 3.1 and 3.2
The tests carried out to confirm the suspected presence of a TSE different from those referred to in points 3.1 and 3.2 shall include at least a histopathological examination of brain tissue. The competent authority may also require laboratory tests such as immunocytochemistry, immuno-blotting, demonstration of characteristic fibrils by electron microscopy or other methods designed to detect the disease associated form of the prion protein. In any case at least one other laboratory examination shall be carried out if the initial histopathological examination is negative or inconclusive. At least three different examinations shall be carried out in the event of the first appearance of the disease.
In particular, where BSE is suspected in a species other than bovine animals, samples shall be submitted for strain-typing, where possible.
4. Rapid tests
For the purposes of carrying out the tests in accordance with Article 5(3) and Article 6(1), the following methods shall be used as rapid tests within the meaning of this Regulation:
- immuno-blotting test based on a western blotting procedure for the detection of the protease-resistant fragment PrPRes (Prionics Check test),
- chemiluminescent ELISA test involving an extraction procedure and an ELISA technique, using an enhanced chemiluminescent reagent (Enfer test),
- sandwich immunoassay for PrPRes carried out following denaturation and concentration steps (Bio-Rad Platelia test).
5. Alternative tests
