2018年12月19日，加拿大卫生部提议将杏仁中的氰化物列入食品中污染物及其他掺假物质列表。

  

　　据了解，加拿大卫生部关于苦杏仁的现有食用建议为成人每天食用不超过三颗，儿童不建议食用。但大多数的消费者不知道或不遵循这一建议，因此加拿大采取了进一步的风险管理行动来应对因食用生杏仁而导致的急性氰化物中毒的潜在健康风险。

　　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 or naturally present in foods or in some cases intentionally added for fraudulent purposes. Establishing a prohibition or a maximum level （ML） are forms of risk management that may be employed to eliminate or reduce exposure to a particular chemical contaminant in foods. Canadian prohibitions and MLs for chemical contaminants in food are set out in Part 1 and Part 2, respectively, of the List of Contaminants and Other Adulterating Substances in Foods, which is incorporated by reference into section B.15.001 of Division 15 of the Food and Drug Regulations （the 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 prohibitions and 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.
