Routine epidemiological surveillance for salmonellae in poultry relies initially on environmental sampling. Intensive, spatially homogenous sampling, as conducted within this study, confirmed that the sampling methodology conducted within a poultry environment is a nontrivial part of sampling design. The frequency of sampling is especially important when the prevalence ofSalmonella spp. is low. These factors must be taken into consideration in the design of studies for the detection of salmonellae in poultry sheds.
