Use of Sodium Dichloroisocyanurate for Floor Disinfection

Bactericidal efficacy on surfaces was assessed using a carrier test based on the British Standard EN 13697. S. aureus strains from clinically infected ITU patients were used. When 1000 ppm was applied to clean surfaces contaminated with S. aureus strains, NaDCC achieved a bactericidal effect after 30 s. The researchers observed a difference in inactivation kinetics between individual strains when experiments were conducted under dirty conditions, particularly among the MRSA strains, although all isolates remained susceptible to exposures of 2 min. Considerably longer contact times (3.5 min) were required when the strains were exposed to a dilute 500 ppm solution in the presence of an organic load. The researchers found no difference in susceptibility between MSSA and MRSA. J Hosp Infect. 2009;72:279-81.
