Notice of Modification to the List of Permitted Food Additives with Other Accepted Uses to Enable the Use of Copper Sulphate in Preserved Duck Eggs - Reference Number: NOM/ADM-0106

Health Canada's Food Directorate completed a detailed safety assessment of a food additive submission seeking approval for the use of copper sulphate in the manufacture of preserved duck eggs. 

Copper sulphate is already permitted for use in Canada as a food additive, more specifically as a fining agent in wine. The intended use of copper sulphate in the manufacturing process of preserved duck eggs is to improve consistency in achieving the desired characteristics of the finished product.

As no safety concerns were raised through Health Canada’s assessment, the Department has enabled the use of the food additive copper sulphate described in the information document below by updating the List of Permitted Food Additives with Other Accepted Uses, effective October 6, 2017.

The purpose of this communication is to publically announce the Department's decision in this regard and to provide the appropriate contact information for any inquiries or for those wishing to submit any new scientific information relevant to the safety of this food additive.
