ABSTRACT
The proper use of products containing sodium hypochlorite, ammonium salts and triclosan has proved to be effective in the elimination of infectious agents in the household environment. Our objective was to evaluate the immediate, one-week and one-month efficacy of controlled use of five products containing these components, compared to other commonly used products. Within a six month period, thirty two middle-class homes from Buenos Aires City and suburbs were included in this open-label, randomized, parallel-group intervention study. Sixteen homes were randomized to use products containing sodium hypochlorite, ammonia and triclosan in the kitchen and bathroom during one month. The remaining maintained usual practices for domestic cleaning. Bacterial counts and identification were performed from samples taken from each study site. Baseline samples (no group discrimination) contained a mean bacterial count in kitchen of 66.0 CFU/cm², and in bathroom 40.1 CFU/cm². Samples taken immediately after-cleaning (no group discrimination) contained: kitchen 0.8 CFU/cm²; bathroom < 1 CFU/ cm². After one week (intervention group vs. control group) contained: kitchen 18.0 vs. 32.5 CFU/cm²; bathroom 12.7 vs. 7.7 CFU/cm². After one month (intervention group vs. control group): kitchen 60.1 vs. 62.1 CFU/cm²; bathroom 37.0 vs. 42.0 CFU/cm². A remarkable dicrease of bacterial load was observed in both groups, which suggests that not only product quality but also education for suitable use plays a key role in successful house disinfection. This approach could be an important tool for improving prevention of foodborne infections since fecal coliforms widely predominated in all analyzed samples.
