Bisphenol-A or BPA -- a chemical used primarily to make plastics -- has been under scrutiny in the United States since 2008 when its safety was called into question. Most recently, a study published September 20 in the online NIH journal Environmental Health Perspectives "suggests exposure to BPA is actually much greater than previously thought, and its authors urge the federal government to act quickly to regulate the chemical that is found in baby bottles, food-storage containers and many household products."
One of the researchers, Frederick vom Saal, professor of biological sciences at the University of Missouri, said in a news release that the study "provides convincing evidence" that BPA is dangerous and that "further evidence of human harm should not be required for regulatory action to reduce human exposure to BPA."
According to a New York Times article, the U.S. Environmental Protection Agency says "it is OK for humans to take in up to 50 micrograms of BPA per kilogram of body weight each day. The new study, published in the journal Environmental Health Perspectives, suggests that we are exposed to at least eight times that amount every day."
In August, Canada placed BPA on a toxic-substance list under the Canadian Environmental Protection Act. The country first banned BPA-containing plastic baby bottles in 2008, "but the new move will see BPA removed from all products on store shelves. As a result, Canada will become the first country in the world to declare BPA as a toxic substance."
Five states in the USA -- Connecticut, Massachusetts, Washington, New York and Oregon -- have limits on BPA, particularly in children's products, but California state legislature recently failed to pass a bill that would have eliminated BPA from baby bottles, sippy cups and infant formula cans.
Senator Dianne Feinstein (D-CA) believes BPA should be legislated on a national level and wants to amend the Food and Drug Administration Food Safety Modernization Act currently under consideration in the Senate to ban BPA from children’s food and beverage containers. However, Republicans and industry representatives are pushing back, saying that research hasn't conclusively proven that the chemical is harmful. Senator Feinstein said, "In America today, millions of infants and children are needlessly exposed to BPA. This is unacceptable. If this isn’t a good enough reason to offer an amendment, I don’t know what is."
What is BPA and Why Should You Care?
Bisphenol-A is "a synthetic estrogen used to harden polycarbonate plastics and epoxy resin." It is found in many plastic containers as well as in the lining of canned goods. According to the Environmental Working Group:
Over 200 studies have linked BPA to health effects such as reproductive disorders, prostate and breast cancer, birth defects, low sperm count, early puberty and effects on brain development and behavior. BPA leaches from containers like sippy cups, baby bottles, baby food and infant formula canisters into the food and drink inside where it is then ingested by babies and children. The CDC found BPA in 93 percent of all Americans. Just last year EWG research revealed BPA in umbilical cord blood of newborns, which demonstrates that babies are exposed to this toxic chemical before they are born.
The Environmental Working Group has some tips to avoid exposure to BPA. Raise Healthy Eaters also has a post about How to Become a BPA-Free Family. Maryann Tomovich Jacobsen, a registered dietician, recommends things such as:
- Switching from plastic food storage containers to glass
- Reducing your canned goods use
- Using stainless steel water bottles and more.
