ASF confirmation

Question 1

Measures in the surveillance zone of ASF

Answer 1

o A radius of at least 10km (consider that it is vector-borne)
o Census of all the holdings
o Ban on the movement & transport of pigs
o Movement restrictions: products, persons, vehicles etc.
o No markets, fairs etc
o Strict cleaning, disinfection, disinsectisation

Question 2

Repopulation in case of ASF

Answer 2

The reintroduction of pigs to infected holdings shall not occur until 40 days after completion of
the cleansing, disinfection and, if necessary, disinsectisation operations in the holding in question.
• As regards open-air holdings, the reintroduction of pigs shall start with the introduction of
sentinel pigs which have been checked and found negative for the presence of antibodies
against African swine fever virus or which come from holdings not subjected to any restrictions
related to African swine fever. The sentinel pigs shall be placed, throughout the infected holding
and shall be sampled 45 days later, and shall be tested for the presence of antibodies
• In case of holdings where the occurrence of disease has been linked to vectors, restocking
shall not take place for at least 6 years unless:
o 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
o It has been possible to show that the persistence of the vector no longer represents a
significant risk of African swine fever being transmitted

Question 3

Vectors and vaccines in ASF

Answer 3

Investigations & measures to eradicate the vectors of the disease (ticks) on the affected holdings
o Search for vectors in soil, sand or dust
