Animal studies have linked BPA exposures to a host of serious health problems, including genetic damage, birth defects, miscarriages, and low sperm count. Several recent human studies have shown toxicity at current levels of exposure, linking it to heart disease, diabetes, infertility, and other problems. Studies have also shown that chemicals in food-contact plastics can leach into our food and drinks.
In response to new regulations, many products for young children are now labeled “BPA free.” But these labels may not tell parents anything about the safety of chemicals used to replace BPA. Because there is no requirement that chemicals are tested for safety before companies use them in the products they sell, manufacturers can simply replace BPA with chemicals that have never been tested for endocrine-disrupting or other health effects. In fact, a 2011 study found endocrine-disrupting activity from almost all food-contact plastic products sampled – including products labeled “BPA-free.” Indeed, some of these “BPA-free” products had higher levels of estrogenic activity than products made with BPA.
