Electric warm-water lavage toilet seats are in wide use as an appliance beneficial for the maintenance of hygiene and the prophylaxis and improvement of conditions such as constipation and hemorrhoids. In this study, we surveyed the bacterial content in the lavage water of warm-water lavage toilet seats, and fecal bacterial contamination of the gluteal and genital regions due to droplet infection from post-defecation lavage, to examine the problems inherent to the use of such lavage units. The presence of viable bacteria in lavage water was confirmed in this survey. Viable bacterial counts in lavage water were 3-times higher in household units compared to units in public facilities, suggesting a correlation with the replenishment of lavage tank water with fresh water containing residual free chlorine.
电动温水冲洗马桶座圈作为一种有利于保持卫生以及预防和改善便秘、痔疮等状况的器具被广泛使用。在本研究中，我们调查了温水冲洗马桶座圈冲洗水中的细菌含量，以及排便后冲洗产生的飞沫感染导致的臀部和生殖器区域的粪便细菌污染，以研究使用此类冲洗装置所固有的问题。本次调查证实了冲洗水中存在活菌。家庭用装置冲洗水中的活菌数是公共设施中装置的3倍，这表明与用含有残余游离氯的淡水补充冲洗水箱水有关。
