About the Section

The Section provides analytical and advisory support to the Food and Environmental Hygiene Department and the Agriculture, Fisheries and Conservation Department for the protection of public health and for support of their statutory functions under the Harmful Substances in Food Regulations and the Public Health (Animals and Birds) (Chemical Residues) Regulation of Cap. 132 and Cap. 139 respectively.

Responsibilities

This Section conducts analyses for enforcement of the following regulations under the Ordinances:

  • Harmful Substances in Food Regulations under the Public Health and Municipal Services Ordinance (Cap. 132)
  • Public Health (Animals and Birds) (Chemical Residues) Regulation under the Public Health (Animals and Birds) Ordinance (Cap.139)

In addition, the Section undertakes the examination of veterinary drug residues in food and food animals that are of health and public concern. It is planned that 37,500 tests will be conducted in 2007/08. The samples are examined for agricultural and veterinary drug residues including beta-agonists, antibiotics and synthetic hormones and other chemicals as listed in the concerned regulations.

Targets and Key Indicators

Key Performance Measures Relating to the Statutory Testing of Food Samples

Targets

Testing of Food Samples* Targets 2006
(Actual)		 2007
(Actual)		 2008
(Plan)
Samples relating to food poisoning within one working day (%) 100 100 100 100
Food samples for regulatory compliance purposes within target reporting time averaging 19 working days (%) 95 98 97 95
Food complaint samples within target reporting time averaging 25 working days (%) 80 75 80 82

* Different samples require different analytical procedures, thus different target reporting time applies. The quoted number of working days required represents an average of target reporting time for the different samples within the category.
