The Electrical and Mechanical Services Department (EMSD), a government agency in Hong Kong, announced yesterday the latest results from a series of Legionella testing performed in the region.  This agency posts information about the latest Legionella statistics from water cooling tower samples on a regular basis.  The EMSD also posts its process for Regulatory Control of Cooling Towers on its website. Some of its regulatory actions include random water cooling tower inspections and testing for buildings that have discharged their responsibility for maintaining cooling towers.  If Legionella bacteria counts (LBC) are equal to or greater than the threshold, a notice is sent out necessitating emergency decontamination.

In the most recent sampling, EMSD collected 77 water samples from cooling towers in 71 buildings.  Six samples came back positive for Legionella LBC at or over the threshold.  The EMSD has also issued notices through the Public Health and Municipal Services Ordinance to these Legionella-positive buildings requiring that remediation steps be taken.
