ABSTRACT - Salmonella Typhimurium (S. Typhimurium) is one of the common food pathogens which may cause gastroenteritidis in human and animals. The microorganism also causes the economic loss in animal farming and food industry. In this study, the disinfection efficacy of a powder disinfectant containing phosphate compounds as a main ingredient, was evaluated against S. Typhimurium. A bactericidal efficacy test by broth dilution method was used to determine the lowest effective dilution of the disinfectant following exposure to test bacteria for 30 min at 4oC. The disinfectant and test bacteria were diluted with hard water (HW) or organic matter suspension (OM) according to treatment condition. On HW and OM conditions, the bactericidal activity of the disinfectant against S. Typhimurium was 4- and 2-fold dilutions, respectively. As the disinfectant composed to phosphate compounds possesses bactericidal efficacy against pathogenic bacteria such as S. Typhimurium, the powder disinfectant can be used to control the spread of bacterial diseases.
