Abstract
In order to clarify the actual state of bacterial contamination of infant toys, cooperation was obtained from 18 pediatric outpatient facilities, 19 nurseries and 21 homes with nursery-age children. The stamp method was utilized to collect bacteria from picture books, plastic dolls, plastic rattles, rubber balls and play blocks, and analysis performed on the level of general bacterial contamination.
As a result, 91.2% (250 out of 274 objects) of the toys were found to be contaminated with bacteria. By comparisons of the locations collected, significant differences were recognized with the pediatric outpatient facilities having the lowest level of bacterial contamination. In comparing the level of bacterial contamination based on types of material, rubber objects were found to be the highest and paper toys the lowest. When comparing the level of bacterial contamination in homes according to use or non-use of diapers, toys in those homes where diapers were used showed significantly higher contamination.
From the above, it can be concluded that nearly all toys are contaminated with bacteria, and that it is necessary to reestablish the potential for toys to serve as mechanical vectors. Furthermore, to deal appropriately with environmental facilities in accordance with the status of bacterial contamination of the toys, it will be desirable to improve sanitary control.
