Legionella Testing & Analysis

 

Managing aerosol risks through advanced detection to ensure respiratory safety in public and industrial spaces.
 

Legionella bacteria are a major public health concern, often thriving in complex water systems and spreading via contaminated aerosols. At Weshin Inspection Tech , we follow rigorous international standards (e.g., ISO 11731) to provide high-sensitivity Legionella detection services, helping facilities mitigate the risk of Legionnaires' disease.

 

The Importance of Legionella Monitoring

 

Regular screening is a cornerstone of building safety and liability management:

  • Prevention of Outbreaks: Monitoring cooling towers, HVAC systems, and spa pools to identify and treat microbial growth before it reaches infectious levels.

  • Public Health Compliance: Essential for hotels, hospitals, and high-occupancy buildings to satisfy municipal hygiene audits and environmental safety standards.

  • Biofilm Control Verification: Assessing the efficacy of secondary disinfection and pipe maintenance in controlling bacteria hidden within persistent biofilms.

  • Specific Pathogen Identification: Identifying the highly virulent Legionella pneumophila serogroup 1, responsible for the majority of clinical infections.
