The Federal Government completed a detailed safety assessment of a food additive submission seeking approval for the use of ground limestone as a colouring agent in hard and soft candies and in edible inks for writing on certain confectionery. The results of Health Canada's evaluation of available scientific data support the safety of ground limestone for use as a colouring agent in such unstandardized confectionery.

The purpose of this communication is to publically announce the Department's intention 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.
