Important Health Advisory: Hachioji City Issues Guidance on Legionnaires’ Disease Prevention in Public Facilities
Hachioji City has released a crucial announcement, “[お知らせ]生活関係営業施設等におけるレジオネラ症対策について” (Announcement: Countermeasures Against Legionnaires’ Disease in Lifestyle-Related Business Facilities, etc.), published on August 21, 2025, at 15:00. This advisory serves as an important reminder and guide for businesses and facilities within Hachioji City that are potentially susceptible to Legionella bacteria, emphasizing the need for robust prevention measures to safeguard public health.
Legionnaires’ disease is a serious, sometimes fatal, form of pneumonia caused by the Legionella bacteria. These bacteria are commonly found in warm, stagnant water sources, such as those found in cooling towers, hot water systems, whirlpools, saunas, and decorative fountains. When water mist containing the bacteria is inhaled, it can lead to infection.
The announcement from Hachioji City highlights the responsibility of “lifestyle-related business facilities, etc.” in implementing effective strategies to control and prevent the proliferation of Legionella bacteria. This encompasses a broad range of establishments that utilize water systems and could pose a risk to the public, including but not limited to:
- Hotels and Ryokans: Particularly those with extensive hot water systems, spas, and swimming pools.
- Public Baths and Onsen (Hot Springs): Facilities that rely on heated water circulation systems.
- Sports Facilities and Gyms: Especially those with hot tubs, saunas, and swimming pools.
- Hospitals and Nursing Homes: Where vulnerable individuals may be present and require strict hygiene protocols.
- Commercial Buildings with Cooling Towers: Essential for air conditioning systems.
- Leisure Facilities: Such as amusement parks and water parks with water features.
The core message of the advisory is to encourage proactive management and regular maintenance of water systems. Key recommendations likely include:
- Regular Cleaning and Disinfection: Ensuring that water systems are thoroughly cleaned and disinfected at appropriate intervals.
- Water Temperature Management: Maintaining optimal temperatures for hot and cold water systems to discourage bacterial growth. This typically involves ensuring hot water is kept sufficiently hot and cold water sufficiently cold.
- Preventing Stagnation: Implementing measures to prevent water from becoming stagnant in pipes and tanks, which can create ideal breeding grounds for Legionella. This might involve regular flushing of less-used outlets.
- Proper Maintenance of Cooling Towers: Cooling towers require specific and diligent maintenance schedules to prevent the growth and dissemination of Legionella bacteria.
- Regular Water Quality Monitoring: Conducting regular testing of water systems to detect the presence of Legionella bacteria and assess the effectiveness of control measures.
- Staff Training and Awareness: Educating staff responsible for facility management on the risks associated with Legionella and the proper procedures for prevention.
Hachioji City’s proactive issuance of this advisory underscores its commitment to the health and safety of its residents and visitors. By providing clear guidance to businesses, the city aims to minimize the risk of Legionnaires’ disease outbreaks and ensure that public facilities are safe environments for everyone.
Facility operators and managers are strongly urged to review the detailed information provided in the official announcement on the Hachioji City website. Adherence to these guidelines is paramount in protecting public health and maintaining the trust of the community.
