Sampling frame
Article 2
1. The sampling for the purpose of the survey shall be carried out on holdings containing at least 500 fattening turkeys or 250 breeding turkeys. On each selected holding of fattening turkeys, one flock of the appropriate age shall be sampled. However, if the calculated number of flocks to be sampled as set out in the technical specifications is higher than the number of holdings available with at least the number of turkeys specified in the first subparagraph, in order to achieve that calculated number of flocks, up to four flocks may be sampled on the same holding. Where possible those additional flocks from a single holding shall be from different turkey houses and samples taken in different months. If the number of flocks to be sampled is still not sufficient, more than four flocks may be sampled on the same holding, larger holdings being focused on. If the number of flocks to be sampled is still not sufficient, flocks may be sampled on holdings with fewer turkeys than specified in the first subparagraph. 2. Sampling shall be performed by the competent authority or under its supervision.
