A rule revision to strengthen examination of water of the bathtub water is carried out from July 1, 2010 to plan a public bath in the prefecture, the prevention of outbreak of the Legionella symptom in inns and prevention of infection spread in Toyama.
Reinforcement contents of the examination of water
- It is said that it is subject to examination about all bathtub water.
Based on the detection situation of the Legionella genus bacteria, I extend the subject of examination which I limited to a circulation-type bathtub until now in all bathtubs (including bathtubs flowing constantly from the source). - When the Legionella genus bacteria are detected by examination of water, I make a report (report) from a person of business promptly in the public welfare center.
