Definition of animals suspected of being infected with anthrax
• were in contact with animal that died of, is diseased or suspicious to anthrax within 20 days before confirmation • consumed feedstuff or water of the same origin as that of an animal that died of, is diseased or suspicious to anthrax • grazed on a pasture infected with anthrax without vaccination 2 weeks to 6 months before
Definition of animals diseased by anthrax
• typical clinical signs • characteristic lesions in the organs (post mortem, meat inspection) • laboratory diagnostics
Official measures in case of animals diseased with anthrax
• separation • immediate treatment • change of feedstuffs, drinking water, no grazing
Official measures in case of animals suspected of being infected with anthrax
- vaccination and 14 day observation
- cattle and horses: take temperature
- sheep, goats and pigs: daily observation
- in case of clinical signs or fever: treatment
Official measures in case of confirmation of African swine fever on a holding
- all the pigs on the holding are killed and their carcasses processed
- all contaminated material or waste must be destroyed, processed or treated
- cleaning and disinfection of all premises, vehicles and equipment under official supervision
- meat of pigs slaughtered during the period between the probable introduction of the disease and the taking of official measures shall be traced and processed when possible under official supervision
Official measures in case of confirmation of African swine fever on holdings where the occurrence of disease has been linked to vectors
In the case of holdings where the occurrence of disease has been linked to vectors, restocking shall not take place for at least 6 years unless: –> specific operations to eliminate the vector from the premises and places where the pigs are to be kept or can come into contact with the vector have been successfully carried out under official supervision, or –> it has been possible to show that the persistence of the vector no longer represents a significant risk of African swine fever being transmitted.
Definition of Aujeszky’s disease free swine herd
- No infection for 2 years
- Epidemiological conditions
- No vaccination
- Testing of all breeding sows and boars and representative sample of fattening pigs
- Insemination or natural breeding with negative semen/boars
Definition of officially Brucellosis free bovine herd
• no clinical signs (for minimum 6 moths) • no vaccination • all animals over 12 months of age • two serological tests (3-12 month interval) or • 3 milk tests (3 month interval) + 6 weeks later serology • animals introduced originate from official free heard or tested (within 30 days) • regular testing (every year) • general measures (isolation of the holding, records of laboratory exams, separate calving, movement control of visitors, animals, vehicles, control of dogs and cats on the holding)
Definition of positive single intradermal tuberculin test
If clinical signs are observed or there is an increase of 4 mm or more in the thickness of the fold of skin at the injection site
Definition of inconclusive single intradermal tuberculin test
No clinical signs and the increase in the skin fold thickness is more than 2 mm and less than 4 mm
Definition of negative single intradermal tuberculin test
The skin fold thickness increase is not more than 2 mm and there are no clinical signs
Definition of positive comparative intradermal tuberculin test
A positive bovine reaction which is more than 4 mm greater than that of the avian reaction or clinical signs
Definition of inconclusive comparative intradermal tuberculin test
A positive or inconclusive bovine reaction which is from 1-4 mm greater than the avian reaction and there are no clinical signs
Definition of negative comparative intradermal tuberculin test
• a negative bovine reaction • or a positive or inconclusive bovine reaction that is equal or less than a pos-itive or inconclusive avian reaction and there are no clinical signs
Definition of tuberculosis free bovine herd
• no clinical signs • all animals over 6 weeks of age: 2 official intradermal tuberculin test • 1st: 6 months after removal of infected animals • 2nd: 6 months later or 60 days after collection from free herds • animal introduced originate from official free hearts or tested within 30 days • meat inspection, lesion: compulsory investigation • yearly tuberculin test • general epidemiological measures (isolation of the holding, record of labor-atory examinations, movement control of visitors, animals and vehicles, control of dogs and cats on the holding)
Definition of specified risk material in bovine animals
• the skull, excluding the mandible, including the brain and eyes and the spi-nal cord of animals over 12 months of age • the vertebral column, excluding the vertebrae of the tail, the transverse pro-cesses of the lumbar vertebrae and thoracic vertebrae and the wings of the sacrum but including the dorsal root ganglia and spinal cord of animals over 30 months of age • the tonsils and intestines from the duodenum to the rectum and the mesen-tery of animal of all ages
Definition of specified risk material in ovine and caprine animals
• the skull, including the brain and eyes, the tonsils, and the spinal cord of an-imals over 12 months of age or which have permanent incisor erupted through the gum • the spleen and ileum of animal of all ages
Definition of “cohort” in case of confirmation of BSE
A group of bovine animals which were either born in the same herd as, within 12 moths preceding or following the birth of the affected cattle or reared together with the infected animal at any time during the first year of life and which may have consumed the same feed as that which the affected animal consumed during the first year of life
Official measures in case of confirmation of Classical Swine Fever on a holding
- all the pigs on the holding are killed and their carcasses rendered - any material or waste likely to be contaminated is destroyed, rendered or processed - cleaning and disinfection under official supervision - meat of pigs slaughtered during the period between the probable introduction of the disease and the taking of official measures shall be traced and processed when possible - epidemiological inquiry
Official measures in case of confirmation of Classical Swine Fever in feral pigs
- determination of the infected area
- official surveillance on the pig holdings in the area
- official census
- isolation of domestic pigs from feral pigs
- no pigs enter or leave the holding without authorization
- written plan of the measures taken to eradicate the disease in the infected area
- collect information on the –> geographical distribution of the disease –> information campaign to increase hunters awareness –> approximate number of feral pig population in and around the infected area –> method of removal of feral pigs found dead or shot
Use of vaccination in case of confirmation of classical swine fever
- Use of preventative vaccines is prohibited
- The Member State concerned may submit an emergency vaccination plan to the Commission for both farm and feral pigs
- Marker vaccine means a vaccine that can elicit a protective immunity distinguishable from the immune response elicited by the natural infection with the wild type virus by means of laboratory tests
Definition of animals diseased with equine infectious anaemia
- typical clinical signs or
- non-typical clinical signs but demonstration of the virus and/or 2 positive serology (interval of 21 days)
- pathology, histopathology
Definition of animals suspected of being contaminated with equine infectious anaemia
- kept within 90 days with diseased or suspected of being diseased animals
- no clinical signs but 2 inconclusive or 1 positive serology (interval of 21 days)
Rules of taking samples in case of FMD suspicion
• 1 gram of tissue from an enraptured or recently ruptured vesicle • Epithelium samples should be placed in a transport medium which main-tains a pH of 7.2-7.4 • Samples should be kept at 4 C • Esophageal-pharyngeal fluid collected by means of a probing cup
