Little is known about the effectiveness of the cleaning and disinfection methods in use on commercial laying farms in Great Britain. Samples were taken from poultry house structures and equipment of five cage layer flocks, five barn egg production flocks and two free‐range flocks. In the free‐range houses there was a decrease in Salmonella after cleaning and disinfection, although the soil in the paddocks remained contaminated. In the barn and especially the cage layer houses, significant residual contamination remained on the surfaces of buildings and equipment. Wildlife pests were also found to be carrying Salmonella in the disinfected houses and free‐range paddocks.
