[Comment] The Food and Drug Regulations do not include any provisions to control the addition of flavours to foods. There is insufficient data on isophorone in food packaging for the assessors to determine if isophorone intake from food packaging is negligible. [Response] 
The Food and Drug Regulations do not require that food flavouring agents undergo a premarket review by the Government of Canada. However, the Regulations prohibit a number of substances from being present in or added to food, including several agents that might otherwise be used for flavouring food. Isophorone intake from food packaging is negligible as its use in food packaging is limited to the manufacturing of some tin can linings.
