Are polycarbonate plastic baby bottles safe?
Polycarbonate, a clear and rigid plastic, is made
from bisphenol-A (BPA) -- a suspected hormone
disruptor that can alter the body's normal hormonal activity. In 1999, Consumers Union, replicating 1997
U.S. Food & Drug Administration tests on baby bottles, found that
polycarbonate bottles release about 1 part per billion (ppb) of BPA into an
infant formula simulant when boiled for a half
hour. Using a different method,
Several studies show that such low doses cause estrogen-like effects in animals, as documented in Our Stolen Future (Penguin, 1997). One, conducted by Frederic vom Saal at the University of Missouri, found changes in reproductive organ size and sperm production of male offspring of mice that were fed very low doses of BPA during pregnancy. These studies indicate that there may not be an adequate margin of safety between the amount of BPA that an infant receives from bottles and the amount that affects animals, according to Edward Groth, Ph.D., of CU.
