Article 21U.K.Establishment of a restricted zone
1.In the event of an outbreak of a category A disease in an establishment, food and feed business, animal by–products establishment or other locations, including means of transport, the competent authority shall immediately establish around the affected establishment or location a restricted zone, which comprises:
(a)a protection zone based on the minimum radius from the outbreak set out for the relevant category A disease in Annex V;
(b)a surveillance zone based on the minimum radius from the outbreak set out for the relevant category A disease in Annex V; and
(c)if necessary, on the basis of the criteria set out in paragraph 1 of Article 64 of Regulation (EU) 2016/429, further restricted zones around or adjacent to the protection and surveillance zones, where the competent authority shall apply the same measures as those provided for in Section 3 of this Chapter for the surveillance zone.
2.The competent authority shall adapt the boundaries of the initial restricted zone, including the boundaries of the protection, surveillance and the further restricted zones, in the case of the overlapping of two or more restricted zones due to further outbreaks of the category A disease.

(a)establishments keeping animals referred to Article 13(2);
(b)hatcheries;
(c)food and feed businesses, border control posts, animal by-products establishments;
