Division 5.2.1 Number of birds (except ducks, geese and mallards) to be sampled in the poultry holding
United Kingdom
The numbers of birds to be sampled in the poultry holding shall be defined so as to ensure 95 % probability of identifying at least one bird that tests sero-positive for avian influenza, if the prevalence of sero-positive birds is ≥ 30 %.
Blood samples for serological examination shall be collected from all poultry production categories and poultry species from at least 5 to 10 birds (except ducks, geese and mallards) per poultry holding, and from the different sheds, where more than one shed is present on a holding.
In case of several sheds, samples shall be taken from at least five birds per shed.
