Unsung heroes: Tsui Shu-ki and Dr Tang Hau-san are two of the skilled Government Laboratory staff who worked hard to keep Hong Kong safe during the recent melamine scare, using equipment like the High Performance Liquid Chromatograph - Tandem Mass Spectrometer.

The Government Laboratory may be one of the administration's lower-profile departments, yet it is one of the most important, with its skilled and dedicated staff working hard to keep Hong Kong people safe.

This was made clear during the recent melamine scare, during which food, especially dairy products, was found to be tainted with the chemical. The lab's diligent staff worked around the clock to accurately test scores of products and let the Food & Environmental Hygiene Department promptly inform the public of the results.
