The bacterial contamination of Japanese homes and the attitudes of Japanese people toward sanitation were studied. By taking bacterial counts of approximately 90 places each in five homes, this study found kitchens to have the greatest degree of bacterial contamination, followed by bathing rooms. Toilets had less bacterial contamination than was expected. While concern about bacteria on highly contaminated items such as sponges, towels for wiping counters, and other reservoirs/disseminators was common, there was a relative lack of concern regarding contact surfaces such as dining tables. It is believed that an in-depth study of bacterial contamination in the home and concern about it would lead to the promotion of greater public understanding of home sanitation and help to facilitate the provision of useful information and products to the public.
