Food Packaging Materials In today's marketplace there are a variety of different types of food packages used, with a trend towards packages that the food can be cooked inside (e.g., microwave popcorn, steam bags for vegetables). It is important to realize that not all food packages can be safely used for all kitchen applications. For example, not all plastic wraps and bags can b e used in the microwave with your food. Unless the package says it is microwave safe, there is a risk that the heat can cause the plastic to melt in the food, and the risk that chemicals can migrate out of the plastic into the food product. The food manufacturer/seller bears a legal responsibility for safety of packaging materials used. This is due to the potential migration of chemicals from packaging materials to foods. Manufacturers must submit data on: chemical composition of material intended end use extractability of chemicals in packaging materials by food toxicological data on residues Bisphenol A (BPA) Specific regulations exist for some packaging materials with limits set on levels permitted and migration limits. There has been a lot of media attention on Bisphenol A (BPA), which is a chemical used in the production of hard, clear plastic called polycarbonate. Polycarbonate is used in a variety of food containers (e.g., reusable water bottles, infant bottles, food storage containers, outdoor table wear and glasses). BPA is also used in the production of epoxy Oc78 resins, which are used to line the inside of food and beverage cans. Small amounts of BPA may leach out into the food or water stored in these containers, however this exposure is of no risk to Canadians, with the exception of newborns and infants, where the level of exposure can reach that seen in animal studies to cause adverse health effects. The effects seen in animal research have shown that BPA can have estrogen-like activity in the body and may be an endocrine- disrupting agent. The recommendations that Health Canada gives to parents are: Do not put boiling or very hot water into polycarbonate baby bottles (as this can cause BPA to leach at a higher rate). Allow boiled water or liquids to cool to lukewarm before placing in the baby bottle. Allow polycarbonate bottles to cool to room after sterilization / cleaning before adding infant formula. If a parent is concerned about using polycarbonate baby bottles, there are numerous alternatives available in the marketplace that do not contain polycarbonate plastic.
