Abstract
OBJECTIVE: To study the bacterial contamination of antiseptics and disinfections in-use and the risk factors for contamination. MATERIAL AND METHOD: Bacterial contamination of antiseptics and disinfectants was done by culturing in-use solutions. Eight commonly used solutions were studied: alcohol 70%, chlorhexidine 4%, and 0.5%, povidone iodine 7.5% and 10%, tincture iodine 1-2%, lysol 2% and sodium hypochlorite 0.5%. RESULTS: The following risk factors for contamination were found : preparation by unskilled personnel, improper containers and prolonged use. Contamination with bacteria were found in 1.8% of 16,142 samples tested Highest rate of contamination was found in Lysol 2%. There was no contamination of povidone iodine 10% and tincture iodine 1-2%. Bacterial contamination of antiseptics and disinfectants was highest in provincial hospitals and was not found in university hospitals. The rates of contamination correlated with the duration of use. Most bacteria isolated were those found in the environment. CONCLUSION: The contamination of in-use antiseptics and disinfectants was as high as 1.8%. Risk factors for contamination were improper preparation and prolonged use.
