About the Section

Digital Polymerase Chain Reaction System
Digital Polymerase Chain Reaction System

The Section mainly provides analytical and advisory services to support the Food & Environmental Hygiene Department for the protection of public health and safety and for support of its statutory functions under various regulations and ordinances. Its work include the examination of additives and contaminants in food samples, composition and labelling of food products, genetically modified organisms (GMO) and food allergens as well as the identification of oilfish. Analytical reports produced by the Section are admissible in courts of law as evidence of compliance or otherwise with the legislative requirements.
