Background info

• A milking cow farm of very high production
  standards. It performs genetic selection for
  improving production.
• High sanitary level it has a certification of
  absence of EU declared diseases
• 1500 animals in the farm
• The need to increase the population by 10 arises
• (the age of the animals in the farm starts to be
  high and also inbreeding problems have to be
  avoided)

Planning for the restocking
SAPUVETNET

• Before this situation, the breeder decides to
  restock through the importation of animals from a
  nearby country. For this, he consults the animal
  health authorities of his country regarding the
  aspects he has to take into account.
• The sanitary authority indicates two factors to
  be considered from the sanitary point of view
  Public and Animal health

Veterinary intervention, I

• With this initial information, considering that
  you are the veterinarian responsible What is the
  procedure you propose from this moment onwards?
• According to your advice a RISK ANALYSIS IS
  DEVELOPED for this importation (the farm of
  origin is in an area near to Germany and the
  destination is Spain)
• CHANGE THE COUNTRIES WITH THOSE OF INTEREST
  ACCORDING TO TO THE COUNTRY OF THOSE WHO HAVE TO
  SOLVE THE PROBLEM
• Q.1- Which diseases will be considered as
  fundamental in this Risk Analysis?
• Q.2- Which factors do you consider will be part
  of the hypothesis when designing a Risk Analysis?

Veterinary intervention, II
SAPUVETNET

• Starting with this hypothesis
• Q.3- Which are the risks that diseases could be
  introduced in the farm and therefore in the
  country?
• Organize an information tree and perform the risk
  analysis from a qualitative point of view.
• The sanitary authorities of the destination
  country (Spain) ask you, according to an animal
  movement traceability criteria, to design a
  prevention programme for the entrance of
  potential diseases in order to approve the
  importation.
• Q.4- Which points do you think should be included
  in the preventive medicine programme for these
  diseases?

Veterinary intervention, III
SAPUVETNET

• Suppose that once the importation has been
  carried out and after having introduced the new
  animals in the destination farm in Spain an
  ALLARM MESSAGE of the World Organization for
  Animal Health (OIE) arrives informing that cases
  of TUBERCULOSIS have been detected in varius
  farms in the zone from which the importations
  have been carried out.
• Q.5- What should the immediate action protocol be
  at this moment in the destination country (Spain)
  regarding the measures of preventive medicine and
  sanitary policy?

SAPUVETNET
Veterinary intervention, IV

• Diagnosis is carried out and various positive
  animals are confirmed
• Q.6- Which risks, from the point of view of
  Public and Animal health, treating the potential
  disease pose and which measures would you suggest
  for both situations?
