EXPLANATORY  MEMORANDUM 

The  Council  by  Decision  80/1096/EEC  In  1980  introduced  Community 
financial  measures  for  the  eradication  of  classical  swine  fever.  The 
measures  were  linked  with  actions  to  be  taken  under  an  accelerated 
eradication plan which  had  the objective  to render  and keep  the  territory 
of  the  Community  free  of  classical  swine  fever  without  the  necessity  of 
recourse  to systematic  vaccination. This action was planned  to run  for a 
period  of  5  years. Member  States, which  were  not  officially  swine  fever 
free,  were  to  prepare  and  present  eradication  plans  which,  subject  to 
certain  conditions,  could  be  implemented  on  a  regional  basis.  Community 
financial  contributions  were  made  available  for  compensation  to  owners 
for  the  slaughter  and  destruction  of  animals,  emergency  vaccination, 
systematic  vaccination  for up to 2 years and  for serological  tests. 

The  5  years  period  initially  allowed  for  disease  eradication  was  later 
extended  to 6  years  and  in  1987  supplementary  measures  were  added  for a 
period  of  4  years  extending  the  total  period  for  implementation  of 
eradication  plans to 10 years. 

At  the  time  that  these  eradication  plans  were  coming  into operation,  an 
epidemic  of  classical  swine  fever  occurred  in  Belgium.  The  disease 
subsequently  appeared  in  the  Netherlands  and  certain  areas  of  Germany. 
The  highest  annual  number  of  outbreaks  recorded  within  the  Community 
during  the  implementation  of  the  accelerated  eradication  plans  was  in 
1984, when  a  total  of  1272 outbreaks  occurred.  Since  then  the  situation 
has gradually  improved  except  for  a period  in 1990, when  an epidemic  was 
experienced  in Belgium.  By  and  large  the  strategy  -  the  non-vaccination 
and  stamping-out  policy  -  has  been  successful  as  8  of  12 Member  States 
now  fulfill  the  requirements  for  recognition  as  officially  swine  fever 
free  Member  States  and  4  Member  States  have  large  areas  which  at  the 
level of  regions comply  with  the conditions  for  recognition. The ultimate 
goal  of  eliminating  classical  swine  fever  virus  from  the Community  is in 
sight  although  the  rather  recently  reported  occurrence  of  the  disease  in 
the  European wild  boar  in two areas  (Hessen, Germany  and  Tuscany,  Italy) 
may  have postponed  the date. 

Experience  gained  during  the  implementation of  the eradication  plans  and 
the completion  of  the single market  justify  the modifications of  existing 
working  procedures  and  amendments  to  existing  legislation  concerning 
disease  eradication  and  trade  in  live  pigs,  fresh  pigmeat  and  pigmeat 
products.

The  attached  report  describes  the disease  situation,  rules  for  trade and 
measures  applied  to  classical  swine  fever  eradication  since  1980, while 
proposals  for  amending  legislation  are  presented  in  respect  of  Council 
Decision  80/1096/EEC  and  Council  Directive  80/217/EEC,  80/1095/EEC, 
64/432/EEC, 72/461/EEC, 80/215/EEC and 72/462/EEC. 

Finally  it  is the  intention by Commission  Decision  to add classical  swine 
fever  to  the  list  of  diseases  in  Article  3(1)  of  Council  Decision 
90/424/EEC on expenditure  in the veterinary  field.

Report  from the Commission  to the Council  on  the 

classical  swine fever situation  in accordance 

with Article 4b(2) of Council  Directive 64/432/EEC 

of  26 June 1964 on animal  health  problems 

affecting  intra-Community  trade  in bovine 

animals and swine 

INTRODUCTION 

The  occurrence  of  animal  diseases  has,  since  the  earliest  days  of  the 

Community,  been  an obstacle  to  the  creation of  a  common market  based  on 

freedom  of  trade  in  livestock,  meat  and  products  of  animal  origin. 

Disparities  between  health  standards  in  the  Member  States,  between  the 

methods  used  to  control  animal  diseases  and  between  the  prophylactic 

measures applied on  the farm have restricted  the marketing of  such  goods. 

It  is  indeed  unreasonable  to  jeopardize  the  high  standards  of  health 

achieved  by  a  Member  State  by  obliging  it  to  admit  to  its  territory 

livestock  or  products  which,  if  not  reliably  guaranteed  as  safe,  are 

liable to reintroduce diseases which have been eradicated at  considerable 

technical  and  financial cost. 

Classical  swine  fever  is  regarded  as  one  of  the  economically  most 

important  diseases  affecting  the  pig  industry.  It often  produces  a  high 

mortality  and  causes  further  setbacks  in pig  farming  due  to  abortions, 

retarded  growth,  etc.  The  importance  of  the  disease  was  taken  into 

account  at  the  time  of  the  first  enlargement  of  the  Community  when, 

because  of  exceptional  circumstances  in  the  acceding  Member  States, 

authorization  was  given  for  them  to  maintain  their  national  laws  on 

imports,  namely  the  ban  on  imports  from  countries  with  outbreaks  of 

classical  swine  fever  and a policy of  vaccination. 

-  5 -

In order  to dismantle  these  barriers  to  trade, the Community  decided  in 

1980  to eradicate  classical  swine  fever  from  the whole  of  its  territory 

by  applying  a  common  policy  of  slaughter  and  gradual  abolition  of 

systematic  vaccination  for  the  purposes  of  prevention.  This  kind  of 

common  strategy  was  the only way of  ensuring  the  liberalization of  trade 

and  the  establishment  of  a  true  internal  market  that  might  otherwise 

serve as a network  for  the propagation of  this epidemic disease. 

I.  DISEASE ERADICATION 

1.  Eradication plans  in Member  States 

Plans  for  the eradication of  classical  swine  fever  were  launched  in 

the  early  1980's  to  stamp  out  the  disease  from  those  Member  States 

where  it still  existed.  Likewise, plans were  introduced  for Greece, 

Portugal  and Spain at  the time they  joined  the Community. 

The  final  goal  of  each  plan  was  that  the  Member  State  concerned 

should  obtain  a status  as  "officially  swine  fever  free" based  on  the 

following  health  requirements : 

-  no swine  fever  to be detected during the previous  12 months, 

-  vaccination  against  swine  fever  had  not  been  authorized  for  at 

least  12 months, 

-  holdings not  to contain pigs vaccinated  against  swine  fever during 

the  last  12 months. 

Community  financial  measures  to  support  the  eradication  of  the 

disease, Council  Decision 80/1096/EEC,  include provisions  for payment 

of : 

-  compensation for slaughtered  and destroyed animals, 

-  vaccination  (emergency  vaccinations  and  prophylactic  vaccinations 

for a  limited period only as part of an eradication  plan), 

laboratory  tests for detecting  the disease. 

- 6 -

The  measures  applied  by  individual  Member  States  to  eradicate 
classical  swine  fever  were  in  accordance  with  the  provisions  laid 
and 
down 
Decision 80/1096/EEC, but  the application of  the measures have varied 
in respect of 

Directive 80/217/EEC, 

80/1095/EEC 

Directive 

in 

-  the period allowed  for prophylactic vaccination, 
-  the  priority  given  to  the eradication  of  classical  swine  fever  on 

a regional  level. 

Table  1 provides  information on  the operation of national  eradication 
plans. 

2.  Vaccination 

In  the  past  there  have  been  two  main  strategies  for  the  control  of 
classical  swine  fever. 

be 

might 

which 

The  first  was  based  on  a  systematic  and  comprehensive  vaccination 
indefinitely;  different 
programme 
vaccination  programmes  were  available  and  if  properly  implemented 
vaccination  would  normally  prevent  acute  and  subacute  disease 
outbreaks.  Pig owners knew that  they could  live with  the disease and 
stay  in business.  The  disease  was controlled, but  not  the  infection 
causing  it. 

continued 

The  second  strategy  was  a policy  based  on  the eradication  of  disease 
and  elimination  of  the  infection  without  recourse  to  vaccination. 
This  strategy  calls  for  the  slaughter  of  all  infected  pigs  and  the 
tracing  of  their  contacts.  An  important  tool  in tracing  contacts  is 
the  serological  examination  of  blood  samples  for  antibodies  to 
classical  swine  fever virus. 

Systematic  vaccination  is  Justified  where  the  disease  is endemic  as 
vaccination  reduces  immediate  losses.  Such  situations  occurred  in 
Member  States during  the 1960s  (there were more than 6 000 outbreaks 
in 1961) and  in the 1970s  (more  than 5 000 outbreaks  in  1972).

-  8 -

If  however,  classical  swine  fever  outbreaks  are  sporadic  or  rare, 
vaccination  is an unnecessary  extra cost. 

The  simultaneous  use  of  both  strategies  creates  major  problems  for 
the movement  of  animals  (trade),  and  the  tracing  of  contact  animals 
moved  to and from diseased  herds  (epidemiological  investigations). 

A  Commission  funded  study of  the epidemiology  and economics of  swine 
fever  eradication  within  the  Community  carried  out  during  the  mid-
1970s<1),  concluded  in favour  of  adopting  a non-vaccination policy. 
The decision  to cease vaccination was  taken  in 1985. 

A  number  of  third  countries  such  as  Australia,  Canada,  the 
Scandinavian  countries,  New  Zealand  and  the  USA  have  successfully 
applied  a  non-vaccination  policy  for  a  number  of  years.  Once 
vaccination was prohibited,  it was never  thereafter  utilised. The ban 
on  the use of  vaccine  in these  countries was  linked  to  a  ban  on  the 
importation  of  pigs,  fresh  pigmeat  and  untreated  products  from 
vaccinating  countries.  With  the  establishment  of  the  single  market 
it  is  important  to  continue  with  a  non-vaccination  policy  in  the 
light  of  intra-Community  trade  as  well  as  of  trade  with  third 
countries. 

3.  Disease situation 

Outbreaks  of  classical  swine  fever  during  the  1980s  have  been 
recorded  in  10  out  of  12  Member  States,  Annex  1.  The  recorded 
outbreaks  from  1980-1989 totalled 3 745, compared  to 13 553 outbreaks 
recorded  from  1970-1979.  Two  Member  States,  Belgium  and  Germany, 
have  during  the  1980s  experienced  outbreaks  every  year,  while  two 
Member  States, Denmark  and  Ireland, did not have any outbreaks.

Commission of  the European Communities, 1977. 

- 9 -

The  relative  large  number  of  outbreaks  recorded  in  Germany  during 

1989 and  1990  is to a great extent  due to the occurrence of  classical 

swine  fever  in  wild  boar;  each  wild  boar,  shot  or  found  dead, 

infected  by  classical  swine  fever  is  recorded  as  an  outbreak. 

Information on  the number  of outbreaks  recorded  in domestic pigs and 

in the wild boar during  1990  is given  in Annex 2. 

An  analysis  of  outbreaks  to  determine  the  sources  of  infections 

during  1990  has  revealed  that  the major  sources  were  :  fomites and 

contacts with neighbouring herds, Annex  3. 

The  main  diagnostic  method  used  to  diagnose  outbreaks  in  Member 

States  is  the  demonstration  of  viral  antigen  by  the  direct 

immunofluosescence technique, Annex  4. 

4.  Financial  consequences 

Community  financial  aid  is made  available  to  the Member  States  from 

the  day  when  the  eradication  plans  are  implemented.  In  accordance 

with  the provisions of  Council  Decision  80/1096/EEC  the aid  has been 

aval table to cover : 

-  up  to 50% of  the cost of  slaughter  and  destruction as paid  by  the 

Member  States  in  compensation  to  the  owners  of  slaughtered 

animals, 

-  up  to  0.125  ECU  per  animal  for  emergency  or  prophylactic 

vaccination, provided  that  it  is part of a plan, 

-  up  to  one  ECU  per  sample  examined  in  a  laboratory  in connection 

with detection tests.

Outbreaks of  classical  swine  fever  caused  by  highly  virulent  strains 
of  the  virus  are  normally  readily  recognised  as  they  produce  a 
disease  which  is  characterised  by  rise  in  body  temperature, 
depression,  loss of  appetite, purulent  conjunctivitis, stilted gait, 
incoordination,  diarrhoea  and  a  high  mortality.  During  the  1980s  a 
number  of  outbreaks  have  been  caused  by  strains  of  low  virulence, 
which  produce  weak  or  indistinct  signs  of  disease.  This  type  of 
virus  strain  spreads  rather  slowly  through  a  herd  and  the  infection 
may  be  present  in  a  population  for  some  time  (weeks)  before  it  is 
detected.  Virological  and  serological  testing  methods  are  of 
paramount  importance  for  the confirmation of such  infections. 

The  use  of  rapid  serological  testing  methods  (EL ISA-test),  however, 
have  been  faced  with  problems  in  herds  which  recently  have  changed 
from  having  a  vaccination  status  to  a  non-vaccination  status  as 
detected  antibodies  can  be  caused  by  a  field  virus  or  a  vaccine 
antigen.  Verification  of  the  result  requires  additional  laboratory 
tests,  unless  misinterpretation  can  be  ruled  out  by  individual  pig 
identification and vaccination records. 

-  11 -

The  repeated  epidemics  in some  Member  States  can  be  related  to  the 

dense  population  of  pigs  in  the  affected  areas  and  it  seems  likely 

that  the  introduction  of  virus  strain  of  low  virulence  into  densely 

populated  areas will  create major  eradication  problems;  particularly 

if  large numbers of animals are being moved  between herds. 

The  occurrence  of  classical  swine  fever  in  European  wild  boar  as 

recently  reported  from  the  areas  of  Hessen,  Germany  and  Tuscany, 

Italy  has  added  new  dimensions  to  the  disease  situation;  and  this 

represents  a  permanent  source  of  infection  that  will  remain  within 

the  borders  of  the  Community  for  some  time.  The  importance  of  the 

infected  wild  boar  as  a  source  of  infection  of  domestic  pigs  is 

difficult  to assess, but  it  is evident  that  special  attention must  be 

given  to this matter  in the future. 

Measures  for  thg future 

On  balance,  the  Commission  is  of  the  opinion  that  the  eradication 

programmes  have been well  designed  and by and  large well  implemented. 

At  this  moment  in  time,  however,  it  appears  appropriate  to  draw 

attention  to  certain  topics  which  in  the  future  deserve  special 

attention  due  to the nature of  the disease  and  the completion  of  the 

single market. 

1. The  non-vaccination  policy  should 

continue.  If  emergency 

vaccination  is  carried  out  live  animals  should  remain  in  the 

vaccinal  zone.  Meat,  subject  to  appropriate  heat-treatment,  can 

leave the zone. 

- 12 -

2. Measures  for  the control  of  classical  swine  fever  in the European 

wild boar  should be established. 

3. The  diagnostic  methods  for  the  confirmation  of  classical  swine 
fever  have  been  improved  in  recent  years. These  improved  methods 
should be available and used  in all Member States. 

4. All  Member  States  should  have  contingency  plans  to  ensure  rapid 
implementation  of  adopted  legislation  on  control  and  eradication 
measures. 

5. The  adoption  of  Council  Decision  90/424/EEC  of  26 June 1990  on 
expenditure  in  the  veterinary  field  provides  for  Community 
financial  aid,  in  the  event  of  the occurrence  of  classical  swine 
fever,  within  the  framework  of  this  decision;  thus  classical 
swine  fever  will  be  treated  from a  financial  point  of  view  like a 
number  of  the  other  economically  important  diseases  listed  in 
Article 3 of  the said Decision. 

I  Conditions for  trade 

The status "officially swine fever  free" and  "swine fever  free". 

With  the  aim  of  dismantling  trade  barriers  prior  to  the  total 
eradication  of  classical  swine  fever  from  the  Community,  since  1980 
it  has  been  possible  for  geographical  regions  to  obtain  status  as 
"officially  swine  fever  free"  or  as  "swine  fever  free".  The 
conditions  for  obtaining  the  officially  swine  fever  free  status 
include : 
-  no detection of swine fever  for at  least  12 months, 
-  no  vaccination  against  swine  fever  had  been  authorized  for  at 

least  12 months, 

-  holdings  do  not  contain  pigs  which  have  been  vaccinated  against 

swine  fever within  the  last  12 months 

while  the  condition  for  obtaining  a  "swine  fever  free  status"  is no 
detection of swine  fever  for at  least  12 months. 

-  13 -

In principle a Member  State can at any  time within  its territory  have 

three different  types of  regions e.g.  "officially  swine  fever  free", 

"swine  fever  free" and  no  status  regions.  Where  an  outbreak  occurs 

in an  "officially  swine  fever  free" or  "swine  fever  free" region  the 

status  shall  immediately  be  suspended  by  the Member  State  concerned 

in  accordance  with  the  provisions  of  Directive 64/432/EEC  or 

72/461/EEC.  Depending on the evolution of  the disease  the status may 

be reinstated or withdrawn. 

In general  live animals, fresh  pigmeat  and  pigmeat  products  can move 

freely  between  regions/Member  States  having  the  same  status.  The 

system  set  up  for  trade  has  by  and  large worked  satisfactorily, but 

it  has  been  criticized  on  a  number  of  occasions  for  not  providing 

sufficient  protection  to  Member  States,  which  have  obtained  the 

officially  swine  fever  free  status  for  a  large  number  of  regions, 

but not  the whole  territory. 

When  applying  the  regional  approach  to  disease  eradication  and 

control  it  is  appropriate  to  impose  the  measures  on  the  areas 

directly  affected.  The  present  system  does not  follow  this  approach 

in full  as the status of  regions  is fixed prior  to outbreaks;  thus a 

pig  holding  situated  100km  away  from  an  outbreak  may  lose  trading 

opportunities, while  this may  not  be  the case  for  a holding  situated 

in a neighbouring  region only  15km away  from an  infected holding. 

Measures for the future 

The principle of régionalisation should apply  in respect of classical 

swine  fever  as  it applies  for  foot-and-mouth  disease.  In  the  event 

of  an outbreak  a protection  and  surveillance  zone should  immediately 

be  established  around  the  outbreak.  This  will  ensure  an  immediate 

ban  on  the  movement  of  live  pigs  and  fresh  meat  out  of  an  area 

covering  at  least  300km2.  Should  an  epidemic  develop  additional 

protection  measures  can  be  introduced  in  accordance  with  the 

provisions  of  Council  Directive 90/425/EEC  concerning  the veterinary 

and  zootechnical  checks  applicable  to  intra-Community  trade  in 

certain  live  animals  and  products  with  a  view  to  the  completion  of 

the  internal market. 

-  14 -

III RELATIONSHIP BETWEEN DISEASE ERADICATION AND CONDITIONS FOR TRADE 

The  strategy  to eradicate  classical  swine  fever  has  been  reasonably 
successful  as 8 out of  12 Member  States now fulfil  the conditions for 
being  recognized  as officially  swine  fever  free Member  States  and  4 
Member  States have  large areas which  at a  regional  level  comply  with 
the  conditions  for  recognition  as  officially  swine  fever  free. 
Certain  Member  States  have  encountered  difficulties  during  periods 
following the cessation of vaccination. 

The  elimination  of  classical  swine  fever  from  the  Community  before 
1993  is not  likely.  But  free  movement  of  pigs  and  their  products 
without  spread  of  disease  can  be  established  provided  restrictions

Proposal  for a 
COUNCIL  DIRECTIVE 
amending  Directive 80/217/EEC  introducing 
Community  measures  for  the control  of  classical  swine  fever 

THE COUNCIL  OF THE  EUROPEAN  COMMUNITIES, 

Having  regard  to the Treaty  establishing  the European  Economic  Community, 
and  in particular  Article 43  thereof, 

Having  regard  to the proposal  from  the  Commission, 

Having  regard  to the opinion  of  the European  Parliament, 

Having  regard  to the opinion  of  the Economic  and  Social  Committee, 

Whereas  Council  Directive  80/217/EEC^1),  as  last  amended  by  Directive 
87/486/EEC^2^, 
introduced  Community  measures  for  the  control  of 
classical  swine  fever; 

Whereas  during  the  period  covered  by  Directive  80/217/EEC  the  disease 
has,  thanks  to the measures  adopted  to combat  it, been  eradicated  in most 
Member  States;  whereas,  however,  certain  serious  difficulties  have  been 
experienced  in  eradicating  the  disease  in  areas  with  a  high  density  of 
pigs and  in areas containing  wild  boar; 

Whereas,  in  view  of  the  disease  evolution,  the  availability  of  improved 
diagnostic  methods  and  of  the  completion  of  the  internal  market  for 
1 January  1993,  it  is  necessary  to  amend  the  control  measures  already 
taken  at  Community  level  to control  classical  swine  fever; 

Whereas  these  amendments  are  related  to  cleaning  and  disinfection  of 
infected  farms,  disease  in wild  boar,  the  use  of  crisis  units,  movement 
controls  in protection  and  surveillance  zones, emergency  vaccination  and 
diagnostic  procedures,

DIAGNOSTIC PROCEDURES FOR THE  CONFIRMATION 
OF DIFFERENTIAL  DIAGNOSIS OF CLASSICAL SWINE FEVER 

The  following  guidelines,  standards  and  minimum  criteria  are  laid  down 
for the diagnostic procedures of Classical  Swine Fever  (CSF). 

A.  COLLECTION OF MATERIALS FOR DIAGNOSIS

together  with  ileum or  kidney.  Each  sample of  the  tissue should 
be  placed  in  a  separate  sealed  plastic  bag  and  labelled.  The 
samples  should  be  transported  and  stored 
in  leak-proof 
containers.  They  should  not  be  frozen  but  kept  cool  at 
refrigerator  temperature and tested without  delay.

such 

as 

2.  Blood  samples  for  virus  isolation  from  leucocytes  should  be 
collected  from  pigs  showing  signs  of  fever  or  other  signs  of 
disease.  EDTA or  heparin should  be used  as anticoagulants.  The 
samples  must  be  kept  cool  at  refrigerator  temperature  and 
submitted  to  laboratory  testing without  delay. 

3.  Blood  samples  for  the  detection  of  antibody  as  an  aid  to 
diagnosis  of  clinical  outbreaks  and  for  the  purposes  of 
surveillance,  should  be  taken  from  animals  which  have  recovered 
from  suspect  infection  and  from  pigs  known  to  have  been  in 
contact with  infected or suspect  cases.  In such suspect  holdings 
all of  the first  20 suspect or  in-contact  animals, and  25% of any 
additional  animals, should be sampled.  In order  to ensure a high 
probability of detection of antibody, samples should be collected 
from each unit of  the holding  at this  level. 

B.  THE  LABORATORY  DIAGNOSIS OF  CLASSICAL  SWINE  FEVER 

-  37  -

The  principal  basis  for  the  laboratory  diagnosis  of  CSF  shall  be  the 
demonstration  of  viral  antigen,  virus  or  antibodies  in  organs  or 
tissue  fluids. 

In  the  case  of  inconclusive  results,  the  tests  shall  be  repeated  on 
the  same  samples.  Additional  samples  should  be  collected  from  the 
same  source  if clinical  suspicion  continues. 

Serological  tests  for  the  detection  of  antibodies  may  be  used  as  an 
adjunct  to  diagnosis  in  cases  of  suspect  CSF.  If  the  demonstration 
of  viral  antigen  or  virus  isolation  has  not  been  successful  on 
material  derived  from  animals  giving  rise  to suspicion  of  CSF  or  with 
material  from  holdings which  have  had  contact  with  cases of  CSF,  then 
tests  for  the  detection  of  antibody  shall  be  applied  to blood  samples 
of  animals  which  have  recovered  from  the  suspect  disease  and  from 
those  known  to have  been  in contact  with  the  disease. 

1.  Demonstration of  viral  antigen 

For  the demonstration of  viral  antigen  in organ  tissues, a  direct 
immune  labelling  system  should  be  used  on  thin  cryostat  sections 
(up  to  five  microns)  of  tonsils  and  tissues  of  other  organs  as 
specified  in A  (1).  The  diagnostic  reagent  must  be  a  pestivirus-
specific  polyclonal  antiserum  to  CSF  virus,  labelled  with  a 
fluorochrome,  an  enzyme,  or  biotin,  according  to  the  following 
criter ia: 

(a) hyperimmune  serum  shall  be  prepared  from  pigs  free  from 
infections  or  antibody  which  could  affect  the  specificity  or 
quality of  the  reaction; 

(b)  labelled  immunoglobulin  prepared  from  CSF  hyperimmune  pig 
serum  as  specified  under  (a)  shall  have  a  minimum  working 
titre  of  1/20  as  determined  in  CSF  virus  infected  cell 
cultures  and  confirmed  by  check  tests  on  tissue  sections. 
The working  dilution of  the conjugate  shall  combine  a maximum 
of  signal  with  a minimum  of  background  staining; 

Any  sample  showing  specific  cytoplasmic  reaction  shall  be 
considered  positive  for  pestivirus.  In  such  cases  further  tests 
must  be  carried  out  as described  in B(3). 

-  38 -

2.  Virus  isolation  and  identification  in cell  cultures 

(a) Virus  isolation  from  tissue  samples 

is  performed  on 
susceptible  cell  cultures  of  PK15  or  other  equally 
susceptible  cell  lines.  Organ  suspension  from  a  suspected 
animal  should  be  inoculated  at  a dilution of  1/10. 

(b) Virus  isolation  from  blood  samples,  collected  and  handled  as 
indicated  in paragraph  A(2), is performed  by  the  inoculation 
of  cell  cultures with  buffy  coat  suspension  reconstituted  to 
the original  blood  volume. 

(c) For  detection of  viral  antigen  in the cytoplasm of  Inoculated 
monolayers,  ceil  cultures  shall  be  treated  with  labelled 
polyclonal  antiserum.  The  staining  should  be  applied  at 
intervals from  24 to 72 hours  from  the  time of  inoculation. 

(d) Positive  cultures  should  be  subject 

to  differential 
diagnostic  tests  as  specified  in  B(3).  Negative  results 
after  the  first  cell  culture  passage  may  require  second  or 
even more passages  in order  to  isolate virus. 

3.  Monoclonal  antibody  typing  of pestivirus  isolates 

(a) Duplicates of  tissue cryostat  sections or  cell  cultures which 
give  positive  reactions  with  polyclonal 
antiserum  as 
described  in  B(1)  and  (2)  shall  be  further  examined  by 
labelled  monoclonal  antibodies  to  differentiate  between  CSF 
virus  and  bovine  virus  diarrhoea  (BVD)/border  disease  (BD) 
viruses. 

(b) Only  monoclonal s  which  have  been  officially  recommended  by 
the  EC  Reference  Laboratory  for  Classical  Swine  Fever, 
following extensive characterization, should  be used. 

(c) The  monoclonal s  should  be  grouped  into  four  panels  according 

to the following  criteria:

Each  panel  may  be  represented  either  by  a  single  monoclonal 
or  by  a  mixture  of  the  component  monoclonal  antibodies, 
provided  that  the  spectrum  of  reactivity  corresponds  to  that 
given above.

C.  DETECTION OF ANTIBODY TO CLASSICAL  SWINE  FEVER  VIRUS 

The  detection  of  CSF  virus  antibody  in  blood  samples  is carried  out 
to assist  in the diagnosis of  swine  fever  in holdings containing  pigs 
showing  clinical  signs of  the disease or  in pigs believed  to have had 
contact  with  infected  pigs.  It  may  also  be  carried  out  for  the 
purposes of  surveillance or  for  surveys  in herds of  unknown  status. 

For  these  purposes,  blood  samples  should  be  subjected  to  an  approved 
test. 

The  following  tests are approved  for use and must  be carried  out  with 
the  inclusion of  appropriate  positive  and negative  serum  controls. 

The  virus  strains  to  be  used  for  serological  tests  should  be  agreed 
at  a  meeting  of  the  National  Swine  Fever  Laboratories  (NSFL),  and 
issued  as  required  by  the EC Reference  Laboratory  for  Classical  Swine 
Fever  to the NSFL, upon  request. 

All  test  procedures  used  must  be  shown  to  give  satisfactory  results 
with  CSF  reference  sera  supplied  by  the  EC  Reference  Laboratory  for 
Classical  Swine  Fever. 

-  40 -

1.  The virus neutralization  test 

This  test  is  based  on  the  determination  of  the  50%  endpoint. 
Cultures  are  inoculated  with  mixtures  of  diluted  serum  and  a 
constant  amount  of  virus  after  a  specified  incubation  period  at 
37*C.  The  results  are  based  on  the  absence  of  any  viral 
replication  detectable  by  an  immune  labelling  system.  Either 
neutralization-immunofluorescence  (NIF)  or  the  neutralizing 
peroxidase-1 inked  antibody  (NPLA)  assays  may  be  used.  Detailed 
protocols will  be supplied by  the EC Reference Laboratory  for CSF 
as  required. 

For  screening  purposes  the sera  are  initially diluted  1/10.  When 
a  full  titration  is  necessary  two-fold  dilutions  of  serum 
starting  at  1/10  are  prepared.  Each  dilution  is  mixed  with  an 
equal  volume  of  virus  suspension  containing  100  (+/-  0.5  log10) 
infectious  doses  (TCID 50).  At  least  two  cultures  are  used  at 
each  dilution  level.  After  an  appropriate  incubation  period  the 
cell  cultures  are  fixed  and  viral  antigen  is  detected  by  an 
immune  labelling  system.  The  results  are  expressed  as  the 
reciprocal  of  the  initial  serum  dilution  at  which  half  the 
inoculated  cell  cultures  fail  to show any  specific  labelling.  An 
end-point  between  two dilution  levels  is estimated. 

2.  The enzyme-1inked  immunosorbent  assay  (ELISA) 

Competitive,  blocking  and  indirect  techniques may  be  used  on  any 
suitable  support. 

It  is  recommended  that  the  tests  used  should  minimize  cross-
reactions  with  BVDV  and  other  pestiviruses.  However,  the  test 
system  must  ensure  identification  of  all  CSF  infections,  and  at 
all  stages of  the  immune  response  to  infection. 

Ant i gen : 

The  antigen  should  be  derived  from  or  correspond  to  viral 
proteins of one of  the recommended  CSF  virus strains.  Cells used 
to  prepare  antigen  should  be  free  of  any  other  pestivirus 
infection. 

-  41  -

Antisera: 

Polyclonal  antisera  for  competitive  or  blocking  assays  should  be 
raised  in  pigs  or  rabbits  by  infection  with  one  of  the 
recommended  CSF  virus  strains  or  with  the  lapinized  C  strain. 
Monoclonal  antibodies should  be directed  against  or  correspond  to 
an  immunodominant  viral  protein  of  CSF  virus.  Indirect  assays 
should  use  an  anti-porcine  immunoglobulin  reagent  that  detects 
both  IgG and  IgM. 

The  sensitivity  of  the  EL I SA  should  be  high  enough  to  score 
positive  any  serum  recating  In the  neutralization  test,  and  also 
reference  positive  sera  as  issued  by  the  EC Reference  Laboratory 
for  CSF. 

The  EL I SA  may  only  be  used  with  serum  or  plasma  samples  derived 
from  individual  pigs. 

If  the  EL I SA  procedure  used  is  not  CSF  specific,  then  positive 
samples  should  be  further  examined  by  differential  tests  as 
specified  in section E. 

D.  EVALUATION OF  THE RESULTS OF LABORATORY  TESTING 

1.  The  demonstration  of  CSF  virus  antigen  in organ  tissues  or  cell 
cultures  after  virus  isolation  from  tissue  samples  following  the 
techniques  defined  in B  (1), (2) and  (3) shall  form  the  basis of 
confirmation of  the presence of  the disease except  in the case of 
a  reaction  demonstrated  to  be  due  to  vaccinal  virus  specified 
according  to  B  (3).  The  demonstration  of  BVD/BD  antigen 
according  to B  (3) shall  rule out  suspicion of  CSF  provided  there 
are  no  other  grounds  for  such  suspicion.  Following  unusual  or 
unexpected  results  of  monoclonal  typing  according  to  B  (3) 
pestivirus  isolates shall  be considered  unclassified  and  the herd 
of  origin  regarded  as  suspect  pending  further  testing.  This  may 
include  submission  of  the  virus  to  a  reference  laboratory  for 
characterization,  and  serological  investigations  on  the  herd  of 
origin. 

2.  Following  the  detection  of  antibody  reactive  with  CSF  virus,  the 

herd of origin  shall  be  regarded  as  suspect. 

-  42 -

(a)  In  order  to  rule  out  the  suspicion  of  CSF  raised  by  the 
detection  of  antibody,  the  test  described  in Section E below 
shall  be  used  to  distinguish  between  CSF-reactive  antibody 
that  may  have  been  induced  by  other  pestiviruses  and  such 
antibody due to CSF virus  itself.  All original  samples shall 
be retested  by  the differential  test. 

(b)  If  suspicion  cannot  be  ruled  out  on  the  first  differential 
test,  a  further  test  shall  be  carried  out  at  least  30  days 
later  to  follow up  the possible  spread  of  infection.  All  of 
the  first  20 animals on  the suspect  holding  shall  be  sampled 
and 25% of any additional  animals. 

3.  Interpretation of serological  results 

A virus neutralization  titre of >.  1/10  in any  pig  together  with 
clinical  or epizootiological  evidence giving  rise to suspicion of 
disease shall  constitute a positive diagnosis.  A titre of >. 1/10 
in  any  pig  without  clinical  or  epizootiologiaI  evidence  gives 
rise  to  suspicion  of  disease  and  should  be  followed  by 
differential  diagnostic procedures. 

The same criteria should  be applied  for any pig giving  a positive 
EL I SA result. 

E.  SEROLOGICAL  PROCEDURES  FOR  THE  DIFFERENTIAL  DIAGNOSIS  BETWEEN 

CLASSICAL SWINE  FEVER AND OTHER  PEST IVI RUSES 

1.  Tests  for  the differential  diagnosis of  CSF  and other  pestivirus 
infections  are  based  on  parallel  testing  of  the  sera  with  both 
CSF and BVD/BD virus strains using  fully comparable methods. 

The  CSF  and  BVD/BD  virus  strains  for  use  should  have  been 
officially  approved  (see C  above).  To  rule out  the suspicion  of 
CSF  raised  by  the detection of  antibody, blood  samples  should  be 
examined  by  comparative  end-point  titrations  for  neutralizing 
antibody against  CSF virus and BVD/BD virus. 

In blocking  ELISA,  a  comparison  of  percentage  blocking  with  CSF 
and BVD/BD antigens may be used. 

2.  The  results of  the comparative  serological  tests using  reference 
strains  of  CSF  and  other  pestiviruses  shall  be  interpreted  as 
foI Iows: 

-  43 -

(a)  if  the  comparative  tests  show  that  more  than  one  pig  has 
antibody  to CSF  virus with  no antibody  to other  pestiviruses 
the test  result  is considered positive for CSF. 

(b)  if  the  comparative  tests  show  that  the  titres  to  CSF  virus 
are equal  to or  higher  than  the  titres  to other  pest(viruses 
in more  than one of  the pigs  there shall  be suspicion  of CSF 
and differentiation shall  proceed  as follows: 

-  those  pigs  which  shown  neutralizing  titres  against  CSF 
virus which  are  higher  than or  equal  to  the  titres  against 
other  pestiviruses  shall  be  slaughtered.  Their  tissues 
and,  if  pregnant,  their  fetuses,  shall  be  subjected  to 
examination  for  CSF  antigen  or  virus,  following  the 
procedure defined  in B  (1, 2 or 3 ). 

-  if  CSF  viral  antigen  or  virus  is  detected,  CSF  shall  be 

conf irmed, 

-  if the examination  defined  in the second  indent  above  fails 
to reveal  the presence of CSF antigen or  virus, the holding 
shall  be considered  as suspect  until'a  further  set of blood 
samples collected at  least  30 days  later  has been  subjected 
to further  comparative  tests. 

-  if  these  subsequent  comparative  tests  show  all  animals  to 
have  significantly  (four-fold  or  greater)  higher  titres 
against  BVD/BD  virus  than  against  CSF  virus,  suspicion 
shalI  be ruled out, 

-  if one or  more  animals  show  a titre against  CSF  virus  that 
is equal  to or  higher  than  its titre  to BVD/BD  virus, then 
the result  is considered  positive for CSF. 

(c)  if  the  BVD/BD  titres  are  such  as  not  to  exclude  the 
possibility  of  CSF,  the  holding  shall  be  considered  as 
suspect  and be retested  after  at  least  30 days. 

THE DIFFERENTIAL  DIAGNOSIS OF AFRICAN SWINE FEVER  (ASF) 

ASF  cannot  be  differentiated  from  Classical  Swine  Fever  by  either 
clinical  or  post-mortem  examinations  and  both  of  these  diseases 
should  be  considered  in  the  differential  diagnosis  of  any  acute 
febrile haemorrhagic syndrome of pigs. 

-  44 -

Laboratory  tests  are  essential  to  distinguish  between  the  two 
diseases.  A  positive  diagnosis  in  an  ASF-free  country  should  be 
based on  the  isolation and  identification of ASF virus. 

The  principal  basis  for  the  laboratory  diagnosis of  ASF  shall  be  the 
demonstration  of  virus,  viral  antigen  or  antibodies  in  organs  and 
tissue fluids. 

In  case  of  inconclusive  or  negative  results  of  at  least  2  tests  on 
samples  from animals giving  rise  to suspicion of ASF or with material 
from  holdings  which  had  contacts  with  cases  of  ASF,  additional 
material  should  be  collected  in  the  same  holding  and  from  animals 
which  have been  in contact  with  the disease.

(a) Haemadsorption  (HAD) test 

The  HAD  test  is  carried  out  by  inoculating  either  prepared 
10%  tissue  suspensions  or  blood  collected  in  the  field  from 
suspect  pigs  into  primary  pig  leucocyte  cultures  or  by 
preparing  leucocyte  cultures  from  the  blood  of  febrile  pigs 
inoculated  at  the  laboratory  or  collected  in  the  field. 
Haemadsorption consists of  the attachment  of  large numbers of 
pig  erythrocytes  to  the  surface  of  infected  cells  and  is 
diagnostic  for ASF. 

(b) Pig  inoculation 

A  pool  is made  with  aliquots  of  each  10%  tissue  suspension 
and  2ml  inoculated  intramuscularly  into  each  of  four  pigs: 
two  of  these  should  be  vaccinated  against  CSF  and  two 
unvaccinated.  Pigs  should  be examined  daily  for  increase of

rectal  temperature  and  onset  of  clinical  signs  for  up  to 21 
days.  If  fever  develops  blood  samples  should  be  collected 
for  preparation  of  leucocyte  cultures  for  the  HAD  test 
(autorosette  and  inoculation  of  primary  pig  leucocyte 
cultures).  If  no  clinical  signs  develop  blood  should  be 
taken  for  detection  of  antibodies  after  the  21  day 
observation  period. 

DETECTION  OF  ANTIBODY  INDUCED  BY  ASF-VIRUS  IN  BLOOD  SAMPLES  AND 
TISSUE FLUIDS 

The  detection  of  antibody  in  samples  of  serum  or  tissue  fluid  is 
carried  out  to assist  in the diagnosis of ASF  in holdings  containing 
pigs showing clinical  signs suspicious of disease or  in pigs believed 
to  have  had  contact  with  ASF  infected  pigs.  It may  also  be  carried 
out  for  the  purpose  of  surveillance  or  for  surveys  in  herds  of 
unknown status. 

For  these purposes samples should  be subjected  to an approved  test. 

The  following  are  approved  for  use  and  must  be  carried  out  with  the 
inclusion of appropriate positive and negative serum controls.
