——The requirements on maximum level of lead in spirulina and its product are added;
——The requirements on maximum level of cadmium in lily flower are adjusted;
——The requirements on maximum level of contaminants in formula foods for special medical purpose, complementary food supplement, sports nutrition food, nutritional supplement foods for pregnant woman and wet nurse are added;
——The inspection method standard number is updated;

——Annex A is modified.
National Food Safety Standard - Maximum Levels of Contaminants in Foods
1 Scope
This standard specifies the maximum level indexes of lead, cadmium, mercury, arsenic, tin, nickel, chromium, nitrite, nitrate, benzo(a)pyrene, N-dimethyl nitrosamine, polychlorinated biphenyl, and 3-chlorine-1, 2- propanediol in foods.
2 Terms and Definitions
2.1
contaminant
chemical hazardous substances (in foods) produced in the processes of production (including crop-cultivating, animal-feeding and veterinary-medicating), processing, packaging, storage, transport, sales and eating or brought in by environmental pollution and non-intentionally added
The contaminants specified in this standard refer to those except pesticide residue, veterinary drug residues, biological toxins and radioactive substance.
2.2
edible part
part of food raw material obtained for eating after the non-edible part is removed mechanically (grinding of grain, paring of fruit, shelling of nuts, boning of meat, boning of fish and shelling of shellfish)
Notes:
1 as for removal of non-edible part, non-mechanical means shall not be adopted (e.g. refining process of rough vegetable oil).
2 the quantity of edible part varies based on the different production processes when the same food raw materials are applied to produce different products. If wheat is applied to process oatmeals and whole wheat flour, the edible part makes up 100% of the wheat; if the wheat flour is processed, the edible part percentage is converted according to flour yield.
2.3
maximum level
maximum permissible content of contaminant in edible part of food raw material and/or food product
3 Application Principle
3.1 No matter whether maximum level of contaminant are made, the producer and processor of the food shall take control measures to minimize the contaminant content in foods.
3.2 This standard lists the contaminants which possibly have a larger risk for the public health; the foods with maximum level made are those having larger influence on the exposure of the consumers' diets.
3.3 Food category (name) description (Annex A) is applied to define the application scope of the maximum levels of contaminants and only applicable to this standard. Where the maximum level of a certain contaminant is applied to a certain food category (name), it is applicable to all types of foods within such category (name), except for those under special regulations.
3.4 Maximum levels of contaminants in foods are calculated based on the common edible part of foods, except for those under special regulations.
3.5 If there is requirement of maximum level index on product, the maximum levels of contaminants in dried product are converted based on that in corresponding fresh food by combining dehydration rate or concentrating rate. Dehydration rate or concentrating rate may be determined based on the food analysis, information provided by the manufacturer of foods and other available data information, except for those under special regulations.
4 Index Requirements
4.1 Lead
4.1.1 Maximum level index of lead in foods is detailed in Table 1.
