Sampling frame
Article 2
1. Sampling for the purpose of the survey in flocks of turkeys shall be organised by the Member States and shall be performed from 1 October 2006 on holdings containing at least 500 fattening birds or 250 breeding birds. On each selected holding of fattening turkeys, one flock of the appropriate age shall be sampled. However, in countries where the calculated number of flocks to be sampled is higher than the number of holdings available with at least the above number birds, in order to achieve the calculated number of flocks, up to four flocks may be sampled on the same holding. Where possible the additional flocks from a single holding shall be from different turkey houses and samples taken in different seasons. 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. 2. Sampling shall be performed by the competent authority or under its supervision.
