Abstract

This study was conducted as a field study to select the most effective disinfectants for control of the microbial contamination in poultry farms through evaluation of some commercial disinfectants. All tested commercial disinfectants were diluted with sterile tap water and applied at different concentrations (0.5 and 1.0 %) on contaminated surfaces (concrete) by spraying at a rate of 0.5 liter/m2. The Aerobic Plate Count (APC) on naturally contaminated floor of broiler farm was determined before the application of commercial disinfectants at different concentrations with contact times of 15, 30, 60, and 120 minutes. The results revealed that disinfectants at concentration of 0.5% had little action on the tested pathogens as S. Typhimurium, E. coli and S. aureus after 30 and 60, 90 and 120 minutes contact time. While, application of Virudox-G, Glutarol and Alkadox at concentration of 1% for 120 minutes contact time was efficient and proved 100% reduction either for of the pathogens count. While, Phenodex showed the lowest inhibitory effect on these pathogens.
