Division (a) Food business operators shall sample all flocks of fattening and breeding turkeys in the following way:

sampling of flocks of fattening and breeding turkeys shall take place within three weeks before slaughter. The competent authority may authorise sampling in the last six weeks prior to the date of slaughter in case the turkeys are either kept more than 100 days or fall under organic turkey production according to Commission Regulation (EC) No 889/2008^f1;

sampling of flocks of breeding turkeys shall take place:

• in rearing flocks: at day-old, at four weeks of age and two weeks before moving to the laying phase or laying unit,

• in adult flocks: at least every third week during the laying period at the holding or at the hatchery,

• on the holding in the case of flocks of breeding turkeys laying hatching eggs intended for F1export to a member State or movement to Northern Ireland.

The competent authority may decide to implement one of the options referred to in the second indent of point (ii) to the whole testing scheme for all flocks. However, sampling of breeding flocks laying hatching eggs intended for F2export to a member State or movement to Northern Ireland must take place on the holding.

By way of derogation from the second indent of point (ii), if the F3... target has been achieved for at least two consecutive calendar years in the F4constituent territory, sampling at the holding may be extended to take place every four weeks, at the discretion of the competent authority. However, the competent authority may decide to keep or revert to a three-week testing interval in the case of detection of the presence of the relevant Salmonella serotypes in a breeding flock on the holding and/or in any other case deemed appropriate by the competent authority.
