Bisphenol A (BPA) is a chemical used in polycarbonate plastics (usually hard, clear items like baby and water bottles, disposable tableware, CD packaging, certain medical devices, and some safety equipment). This chemical is used to harden plastics and prevent cans from rusting.
There is controversy over the possible harmful effects BPA may have on humans particularly on infants and children in their developmental phases. Animal studies have shown effects on endocrine functions in animals related to exposure to BPA . The recent panel study suggests the need for further clarification of what level of exposure to BPA might cause similar effects in humans.
Regulatory agencies in Canada, Europe and Japan agree that the current BPA exposure levels through food packaging do not pose an immediate health risk to the general population, including infants and children.
According to the National Toxicology Program, we may breathe in dust and air containing BPA or absorb the chemical through our skin when we swim or bathe. The first federal U.S. report (presently only a draft) states there is some concern that current human exposures of BPA in fetuses, babies and children could cause harmful effects such as behavioral and brain problems, early puberty in girls, and changes in the prostate and mammary glands. However, the official report will not be available until late summer 2008. In the meantime, here are some ways to reduce exposure to BPA in your home:
Advice for Parents - AAP
Breastfeeding is one way to reduce potential BPA exposure. The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for a minimum of 4 months but preferably for 6 months. Breastfeeding should be continued, with the addition of complementary foods, at least through the first 12 months of age and thereafter as long as mutually desired by mother and infant.
Parents considering switching children from liquid to powdered formula should be reminded that mixing procedures may differ, so they should pay special attention in preparing formula from powder.
Parents with babies on specialized formulas to address medical conditions should not switch children off those formulas, as the known risks of doing so would outweigh any potential risks posed by BPA.
Concerned parents can take the following precautionary measures to reduce babies' exposure to BPA:
For plastic containers and sippy cups: look at the bottom for the recycling code (the number in the triangle). Those with a number 7 are made with polycarbonates and may contain BPA. Don't microwave them. Do not boil polycarbonate bottles. Do not wash polycarbonate bottles in the dishwasher. The heat can cause the chemical to "migrate" into the food and drinks.
Consider using certified or identified BPA-free plastic bottles
Use bottles made of opaque plastic. These bottles (made of polyethylene or polypropylene) do not contain BPA
Glass bottles can be an alternative, but be aware of the risk of injury to baby or parent if the bottle is dropped or broken
Call the manufacturer of your baby's formula to find out if they use epoxy resin in their cans.
Buy fresh or frozen fruits and vegetables if you are concerned about the lining inside canned foods.
Try to use glass and/or stainless instead of plastic food containers, bottles and plastic kids cups.
Remember to buy products that say they are BPA free.
Risks associated with giving infants inappropriate (home-made condensed milk) formulas or alternative (soy or goat) milk are far greater than the potential effects of BPA
Don't Panic--Just be BPA smart and start to make some changes in your products while keeping an eye open for more information about BPA to be released.
