Obviously the food safety system in Canada is relatively safe.
To be more serious, all food manufacturers in Canada are subject to the Food and Drugs Act and regulations, which has standards that allow certain ingredients in certain products. So if a loaf of bread includes a product to increase its shelf life, it will have been reviewed and approved by Health Canada as a non-threat to the food safety system.
For apples, they use a controlled atmosphere to reduce the aging of apples. This is not really something that is added to the apples. It's the atmosphere in which the apples are kept that makes a difference.
There is mixed responsibility for it. The provinces have some responsibility for what we call the non-registered sector. Something like bread, for example, would be in a non-registered sector. From that standpoint, the province has the overall responsibility to ensure that what's offered to consumers in that province meets the requirements.
If there is a problem related to an ingredient that is not allowable because it's an allergen or a bacteria and the product needs to be recalled, it's the agency's business. So we oversee action taken to remove products from the market, and the province has the overall responsibility to ensure that stuff that is not necessarily registered by the feds meets the requirements.
