‎3 January ‎2012


The following is issued on behalf of the LegCo Secretariat:

The Legislative Council (LegCo) Secretariat has taken special arrangements today (January 3) to facilitate the conduct of disinfection work for water supply in the LegCo Complex, following a water sample taken from the Dining Hall of the LegCo Complex was tested positive for Legionnaires' Disease (LD).

Starting from around 2.30pm today, the Architectural Services Department has been carrying out disinfection work of the water supply system in the LegCo Complex in order to reduce greatly the risk of LD to users of the Complex. It is envisaged that the whole disinfection work will take about 36 hours to complete. Post-disinfection water samples will then be taken to ensure adequacy of disinfection.

During this period, fresh water supply to the Complex will be suspended while flushing water supply will not be affected.

Some toilets will be temporarily closed. Temporary water supply arrangement has been made with the Water Supplies Department to provide water in toilets and pantries for washing purpose. For drinking water, users of the Complex are requested to use water dispensers instead.

Meanwhile, a briefing was organised by the Centre for Health Protection today in the LegCo Complex to brief LegCo Members, Members' staff and LegCo Secretariat staff on the symptoms of LD and its precautionary measures. Health advice has also been issued to users of the LegCo Complex to prevent LD.


The government announced yesterday (January 2) that nine water samples taken on December 28 and 29, 2011, including one sample from the water tap in the Dining Hall of the LegCo Complex, were tested positive for LD.

SFH on Legionnaires' Disease

Following is a transcript of remarks (English portion) made by the Secretary for Food and Health, Dr York Chow, at a media session at the lobby of West Wing, Central Government Offices, Tamar, this afternoon (January 4):

Reporter: Should the Government be blamed for rushing into the new Central Government Offices?

Secretary for Food and Health: There is no evidence to show that the move-in schedule of our bureaux into this building is the cause of this particular discovery of (Legionella pneumophila bacteria). We have only one patient so far and regarding the discovery of the bacteria, as I said earlier on, we have yet to conclude how significant it is. Since the kind of bacteria is very much fond of water, anywhere with water we can discover the bacteria. But why it is discovered in the outlets of a few faucets and not in the water tank, and whether it is something relating to the water pipes and so on, we have yet to conclude.

Reporter: Will the Government consider imposing tests on Legionella pneumophila bacteria in all new buildings across Hong Kong?

Secretary for Food and Health: I think this is a very difficult question to answer at the moment. Because first of all, usually the Legionnaires' Disease affects individuals in sporadic cases in Hong Kong and there is no huge threat regarding the environment so far. What we have discovered in this building, we cannot really conclude that there is a high risk for other buildings as well. We have to analyse the data that we have received and of course we also need the experts' opinions on that. Dr Thomas Tsang (Controller of the Centre for Health Protection of the Department of Health) may say something from the public health angle of this particular type of bacteria. As far as the World Health Organization is concerned, they do not feel that an extensive test of Legionella pneumophila bacteria in water supply is something necessary for safe water supply. So I think this is not a standard procedure.
