The aim of this study was to observe the effectiveness of disinfection on a broiler farm and in a plant processing the poultry from this farm. The broiler farm was disinfected with a preparation based on peracetic acid while a preparation based on quarternary ammonium salt was used in the processing plant. We evaluated swabs taken from surfaces, which come into contact with broilers and broiler meat. Results of the swabs taken by standard microbiological swabbing method were evaluated with results of the swabs taken by the ATP-bioluminescence method. The microbiological examination included total counts of microorganisms, coliform count and moulds. When using the standard plate counts method on the broiler farm we found that the plate counts in 0% of swabs were < 1, in 12% of swabs ranged between 1 - 100 CFU while in 88% of swabs reached > 100 CFU. In the processing plant, out of 22% of swabs < 1 CFU were recovered, in 36% of swabs plate counts ranged between 1 - 100 CFU and in 42% of swabs plate counts reached > 100. The bioluminescence method was applied only in the processing plant where < 100, 100 - 300 and > 300 RLU were measured in 80, 10 and 10% of swabs, resp. Our observations and results allowed us to conclude that the disinfectants tested appeared suitable for the respective premises and the ATP bioluminescence method could be use as a as a suitable complement for detection of cleanliness of individual surfaces.
