Heavy Metals Testing in Food

Heavy metals present widely in the environment from natural sources and human activities. These metals are dangerous to our health as they tend to accumulate in our food chain. Human, as a top consumer of the food chain, is subject to high risk of heavy metal poisoning.

In order to enhance and update the Regulation with a view to better protecting public health, facilitating effective regulation and promoting harmonization between local and international standards, Centre for Food Safety has introduced Food Adulteration (Metallic Contamination) (Amendment) Regulation, which will commence on 1 Nov 2019.

The existing food categories of “all food in solid form” and “all food in liquid form” with specific MLs targeting individual food/ food groups will be replaced by specifying metallic contamination standards for individual food/ food groups of significant dietary exposure.

Date of Commencement : 1 November 2019

Grace period : between 1 November 2019 and 31 October 2020 ; except – vegetable and their juice, meat and edible offal and animal and poultry, aquatic animal and poultry egg which—

(a) has not been subjected to a process of preservation; or
