Additives and Genetically Modified Foods

A food additive is any chemical substance that is added to food during preparation or storage and that either becomes a part of the food, or affects its characteristics to achieve a particular technical effect.


Chemical Products, Plastic Materials and Packaging

The Canadian Food Inspection Agency (CFIA) plays a vital role in preventing harmful contaminants from entering Canada's food supply. Health Canada registers and regulates agricultural chemicals, including pest control products, veterinary drugs and food additives.

  • Chemical hazards and potential carcinogens
    • Acrylamide and food: The highest concentrations of acrylamide have been detected in potato chips and french fries.
    • Bisphenol A (BPA): Current dietary exposure to BPA through food packaging is not expected to pose a health risk to the general population, including newborns and infants.
    • Inorganic arsenic and seaweed consumption: Tests results have indicated that levels of inorganic arsenic were significantly higher in hijiki seaweed than other types of seaweed.
    • Malachite Green: The substance is not approved by Health Canada for use in food. However it can be readily purchased for treatment of ornamental (aquarium) fish.
    • Melamine: The CFIA implemented a number of activities to monitor for the presence of melamine in food products and livestock feed ingredients from China.
    • Mercury and fish: Certain types of fish should be eaten in moderation because mercury levels in those fish sometimes exceed Canada's mercury guideline.
    • Polychlorinated Biphenyls (PCBs) found in fish: The average intake of PCBs from the Canadian diet is below that which is expected to cause adverse health effects.
  • Chemical residues in food: The CFIA is responsible for the surveillance of chemical residues in foods and their adherence to regulations.
  • Food-processing-induced chemicals: Undesirable chemicals can be formed in certain foods during processing as a result of reactions between compounds that are natural components of the food.
  • Chemical contaminants: Health Canada scientists are responsible for assessing risks to human health from exposure to food-borne chemical contaminants.
  • Homemade pesticides and minimizing risk: Preparing, storing, and using homemade pesticides could pose risks to your health and the environment.
  • Perfluorinated chemicals (PFC) in food: The low levels of PFCs that are found in foods do not warrant dietary changes.
  • Use of Morpholine in apple coatings: Health Canada has determined that morpholine as used in apple coatings does not present a risk to human health.

Trans Fats
