List of Contaminants and other Adulterating Substances in Foods

The List of Contaminants and Other Adulterating Substances in Foods is a two-part list setting out the conditions under which certain foods are adulterated. Part 1 of the List sets out prohibitions for certain substances listed in column 1, which stipulate that no amount is considered acceptable in the corresponding food(s) listed in column 2. Part 2 of the List comprises Maximum Levels (MLs) for various substances in certain foods. A food listed in column 2 of Part 2 is adulterated if the corresponding substance identified in column 1 is present in or on the food in an amount that exceeds the ML set out in column 3. The MLs in column 3 of Part 2 of the List apply only to the food(s) as described in column 2 of Part 2. If any food described in column 2, Part 2 of the List is also sold in a dried, concentrated or diluted form, but MLs have not been established for these alternative forms of the food listed in column 2, then any findings of elevated contaminant concentrations in these alternative forms will be assessed on a case-by-case basis.

This List is incorporated by reference into Division 15 of the Food and Drug Regulations. Additional MLs for other contaminants in foods are available in the List of Maximum Levels for Various Chemical Contaminants in Foods.

To help ensure that Canadians are not exposed to levels of chemical contaminants in their diet that may pose a health concern, as new scientific information becomes available, Part 1 and/or Part 2 of the List shown below may be modified by Health Canada's Bureau of Chemical Safety, Food Directorate. Changes to the List are made following consultation with other federal government partners, as applicable, such as the Canadian Food Inspection Agency, and with relevant stakeholders and the public. Notification of any proposed changes to the List will be provided via a Notice of Proposal (NOP) and parallel World Trade Organization (WTO) notification. Changes to the List are announced via a Notice of Modification accompanied by a WTO notification.

This List is the most current version and was published on September 17, 2018.
