The present study aimed to evaluate the effect of chlorine dioxide (ClO2) on the growth of Salmonella enterica, Pseudomonas aeruginosa and Staphylococcus aureus under laboratory conditions. The tests were performed using ClO2 concentrations of 5ppm, 10ppm and 15ppm, with different exposure times of 5, 10 and 15 min, and were carried out in triplicate for each variable of time, concentration and bacterial strain. Bacterial reduction was determined by counting colony forming units (CFU) and calculating the percentage of reduction by arithmetic average of the results obtained. In addition, an ANOVA statistical analysis was performed to determine the significant differences in bacterial reduction between the different treatments. The results obtained revealed that chlorine dioxide showed a significant effect in the reduction of the growth of the three bacterial strains evaluated; being the concentrations of 10ppm, 15ppm and 15min of exposure where the highest percentage of bacterial reduction was obtained; for Salmonella enterica it was reduced by 87% and 96.50%, Pseudomonas aeruginosa by 77.40% and 95.35% and Staphylococcus aureus by 87.60% and 98.73% respectively. It was found that the effect of ClO2 varied according to concentration and exposure time, i.e. the longer the exposure time the greater the reduction in bacterial growth compared to exposure times of 5min at concentrations of 5ppm where less bacterial reduction was obtained; for Salmonella enterica 17.7%, Pseudomonas aeruginosa 12.03% and Staphylococcus aureus 18.23%.
