Two farms, in southern Sweden, with a history of broilers colonized with VRE were chosen and the houses were either cleaned and disinfected according to the farm’s normal routines (control compartments) or cleaned according to the farm’s normal routines and disinfected with a combination of steam and formaldehyde (test compartments). The farms normal cleaning and disinfection routines included pressure wash and disinfection with a glutaraldehyde (Farm A) or a chloride compound (Farm B). At Farm A; two compartments in one house were used as test compartments and disinfected at a temperature of 50°C for 4 h and two compartments in an identical house were used as control. At Farm B; a single compartment house was used as test compartment and disinfected at a temperature of 60°C for 4 h whereas two compartments in one house (each of the same size as the test compartment) were used as controls. At both farms, 90g of Formalin (23%) per cubic meter were used.

From each farm, caecal samples from ten birds per house or compartment from one (Farm A) or two (Farm B) batches of broilers sent for slaughter preceding the intervention and two batches of broilers following the intervention were analyzed for the presence of VRE.
