The primary source of exposure to BPA for most people is through the diet. While air, dust, and water are other possible sources of exposure, BPA in food and beverages accounts for the majority of daily human exposure. Bisphenol A can leach into food from the protective internal epoxy resin coatings of canned foods and from consumer products such as polycarbonate tableware, food storage containers, water bottles, and baby bottles. The degree to which BPA leaches from polycarbonate bottles into liquid may depend more on the temperature of the liquid or bottle, than the age of the container. BPA can also be found in breast milk.
Some animal studies suggest that infants and children may be the most vulnerable to the effects of BPA. Parents and caregivers, can make the personal choice to reduce exposures of their infants and children to BPA:
- Don’t microwave polycarbonate plastic food containers. Polycarbonate is
strong and durable, but over time it may break down from over use at
- Polycarbonate containers that contain BPA usually have
a #7 on the bottom (http://www.recyclenow.org/r_plastics.html)
- Reduce your use of canned foods.
- When possible, opt for glass, porcelain or stainless
steel containers, particularly for hot food or liquids.
- Use baby bottles that are BPA free.
