Epidemiological inquiry
Article 8
Member States shall ensure that the epidemiological inquiry in relation to suspected cases or outbreaks of African swine fever is carried out on the basis of questionnaires, prepared within the framework of the contingency plans referred to in Article 21.
Such an inquiry shall deal at least with:
1. the length of time during which African swine fever virus may have existed on the holding before the disease was notified or suspected;
2. the possible origin of African swine fever on the holding and the identification of other holdings in which pigs may have become infected or contaminated from the same source;
3. the movement of persons, vehicles, pigs, carcases, semen, meat or any material which could have carried the virus to or from the holdings in question;
4. the possibility that vectors or feral pigs cause the disease to spread.
If the results of this inquiry suggest that African swine fever may have spread from or to holdings located in other Member States, the Commission and the Member States concerned shall be immediately informed.
