Health Canada’s Proposal to Add Maximum Levels for Inorganic Arsenic in Polished (White) and Husked (Brown) Rice to the List of Contaminants and Other Adulterating Substances in Foods
Notice of Proposal - List of Contaminants and Other Adulterating Substances in Foods
Reference Number: NOP/ADP C-2019-2
June 14, 2019
Food contaminants and other adulterating substances are chemicals that may be present in foods at levels that could impact the overall safety and/or quality of foods. These substances can either be inadvertently present in foods or in some cases intentionally added for fraudulent purposes. Establishing maximum levels (MLs) is a form of risk management that may be employed to reduce exposure to a particular chemical contaminant in foods. Canadian MLs for chemical contaminants in food are set out in the List of Contaminants and Other Adulterating Substances in Foods, which is incorporated by reference into section B.15.001of Division 15 of the Food and Drug Regulations. Maximum levels are also set out in the List of Maximum Levels for Various Chemical Contaminants in Foods, which is maintained on Health Canada's website. All MLs for contaminants in food are established by Health Canada's Food Directorate based on scientific evidence and in consultation with stakeholders and are enforceable by the Canadian Food Inspection Agency (CFIA).
Health Canada is proposing to establish new MLs for inorganic arsenic in polished (white) and husked (brown) rice of 0.2 and 0.35 parts per million (ppm), respectively. These MLs would also apply to white and brown rice when used as an ingredient in other foods.
It is the intention of Health Canada to modify Part 2 of the List of Contaminants and Other Adulterating Substances in Foodsas outlined below.
|Item No.||Column 1
Food Footnote 1
|(TBD)||Inorganic arsenic||(1) Polished (White) rice||0.2 p.p.m.|
|(2) Husked (Brown) rice||0.35 p.p.m.|
Arsenic is naturally occurring in the environment, therefore, very low levels are present in various foods. Long-term exposure to elevated levels of inorganic arsenic can contribute to a possible increased risk of certain cancers and other non-cancer effects.
Health Canada is committed to ensuring that dietary exposure to food contaminants is as low as reasonably achievable. Rice represents a significant source of exposure to inorganic arsenic in the diet of Canadians. To minimize dietary exposure to inorganic arsenic, Health Canada is proposing to establish MLs of 0.2 ppm and 0.35 ppm for inorganic arsenic in polished (white) and husked (brown) rice, respectively. The MLs would also apply to the rice portion of rice-containing products.
Canadian surveillance data demonstrate that these MLs are readily achievable for rice and rice products available for sale in Canada.
Other Relevant Information
International Regulatory Actions
In 2014 and 2016, the Codex Alimentarius Commission established MLs of 0.2 ppm and 0.35 ppm for inorganic arsenic in polished (white) and husked (brown) rice, respectively (CODEX STAN 193-1995). The proposed MLs by Health Canada align with those established by the Codex Alimentarius.
The European Commission has established MLs for inorganic arsenic of 0.2 ppm in non-parboiled milled rice (polished or white rice); 0.25 ppm in parboiled rice and husked rice; 0.3 ppm in rice waffles, rice wafers, rice crackers and rice cakes; 0.1 ppm in rice destined for the production of food for infants and young children (Commission Regulation 2015/1006).
The United States Food and Drug Administration (U.S. FDA) has not established regulatory MLs for inorganic arsenic in rice although, in 2016, they issued a proposed action level of 0.1 ppm for inorganic arsenic in infant rice cereals. As of April 2019, this action level has not been adopted as a regulatory ML and thus remains at the proposal stage.
Food Standards Australia New Zealand has not established MLs specifically for inorganic arsenic in rice, although they have set an ML of 1 ppm for total arsenic in cereals grains and milled cereal products (Australia and New Zealand Food Standards Code - Schedule 19). As per Schedule 22 of the Australia and New Zealand Food Standards Code, grains include rice in husk.
Additional Information Request - Rice-Based Foods Intended for Infants and Young Children
Health Canada is considering additional, more protective, risk management measures for rice-containing foods intended specifically for infants and young children. There is evidence that exposure to high levels of inorganic arsenic during critical windows of early development may represent a risk for infants and young children.
To inform possible future risk management measures for rice-containing foods intended for infants and young children, the Canadian Food Inspection Agency will be conducting a targeted survey specifically for these foods in 2019-2020.
Interested stakeholders from the food industry and the public are invited to submit any comments on the proposed rice MLs and data or information on arsenic levels, reduction strategies, or other relevant information pertinent to arsenic in rice-based foods for infants and young children that would inform this work. As noted above, the EC has set an ML of 0.1 ppm inorganic arsenic in rice destined for the production of food for infants and young children and the U.S. FDA has proposed an action level of 0.1 ppm inorganic arsenic in infant rice cereals.
If it is determined that additional MLs for other rice-based foods are warranted then Health Canada will announce its intention to establish these MLs via a Notice of Proposal published on Health Canada's Website.
Implementation and Enforcement - Maximum Levels for Inorganic Arsenic in White and Brown Rice
The proposed current changes to add MLs of 0.2 ppm and 0.35 ppm for inorganic arsenic in polished (white) and husked (brown) rice, respectively, to the List of Contaminants and Other Adulterating Substances in Food will be effective the day on which they are published in Part 2 of the list. Health Canada proposes to publish the changes to the list following the close of the 75-day comment period, provided that no data or information regarding the proposed changes are submitted that would potentially alter the proposal. Changes to the list will be announced via a Notice of Modification, which will be published on Health Canada's Website.
The Canadian Food Inspection Agency is responsible for the enforcement of the Food and Drugs Act and its associated regulations with respect to foods.
