Hong Kong Cap. 132V, made under section 55(1) of the Public Health and Municipal Services Ordinance (Cap. 132), prohibits the import, consignment, delivery, manufacture, or sale for human consumption of any specified food containing a specified metal above the maximum level set in Part 2 of its Schedule. The Schedule, consolidated 5 September 2025 and last amended by L.N. 140 of 2025, tabulates maximum levels (in mg/kg) for seventeen metals across a granular list of foods, from cereals and vegetables to species-level mushroom rows, cocoa-solids-tiered chocolate, canned foods, tea and coffee, salt, honey, and infant formula. HMI loads the 163 current rows whose metals map to the tracked species vocabulary (antimony, total and inorganic arsenic, cadmium, total chromium, lead, methyl-mercury, total and inorganic mercury, nickel, tin, and uranium); barium, boron, copper, manganese, and selenium rows are present in the source but not loaded because they are outside the vocabulary. Basis rules are recorded per row and not conflated: edible-portion after specified removals for meat, offal, and aquatic animals; dried-form for the Note 12 fungi; dry-matter basis for cocoa and chocolate; and reconstituted-to-ready-to-drink for the beverage, milk, and infant-formula rows. One superseded row is retained for date-reconstructability: the pre-2019 Second Schedule tin limit of 230 mg/kg for all food (solid and liquid), documented in the 2011 Government Laboratory standards deck and replaced by L.N. 113 of 2018.
