Legionella bacteria detected in 31 cooling towers across New York

Health officials have identified 31 cooling towers containing Legionella bacteria, prompting immediate safety inspections across several city blocks.

Identified Locations

Recent testing has confirmed the presence of Legionella bacteria in multiple cooling towers located at several specific addresses. The locations identified in the latest report include:

  • 238 E. 81st St.
  • 160 E. 84th St.
  • 114 E. 85th St.
  • 401 E. 88th St.
  • 333 E. 91st St.
  • 354 E. 91st St.

Public Health Risks

Legionella bacteria can cause Legionnaires' disease, a severe form of pneumonia. This occurs when people inhale small droplets of water containing the bacteria, often through mist produced by cooling towers, showers, or fountains.

While the bacteria are not spread from person to person, the risk increases for individuals with weakened immune systems, older adults, or those with underlying lung conditions. Cooling towers are common in large residential and commercial buildings to assist with air conditioning systems.

Monitoring and Compliance

Regulatory bodies monitor these systems to ensure building owners adhere to strict water management protocols. When positive results are detected, specific remediation steps are typically required to disinfect the systems and prevent further aerosolisation of the bacteria.

Ongoing testing remains a standard requirement for high-capacity cooling systems to mitigate the risk of environmental outbreaks within high-density urban areas.
