Investigators confirm for first time that pupae have been found in two public pools
Bloodworms were breeding at the Hammer Hill Road swimming pool, the departments investigating the worm mystery said last night after earlier officially confirming for the first time that pupae had been found in two public swimming pools.
The statement said investigations discovered 5,000 larvae, 300 pupae and 30 adults at different sites around the pool yesterday.
'It is believed that there was natural breeding of [bloodworms] in the compound and investigations will continue tomorrow,' the statement said.
The admission came a day after two pupae and 16 bloodworms - which grow into a mosquito that does not bite humans - were found under artificial turf in the pool area at the Hammer Hill Road facility.
The complex was closed yesterday as hygiene officers, leisure officials and police spent hours investigating. They took water samples and checked artificial turf and rocks around the pool.
The Food and Environmental Hygiene Department also confirmed yesterday that a pupa and 36 bloodworms were found in a water sample taken earlier from the Kwun Tong pool. The department said it had notified the Leisure and Cultural Services Department about that last week.
