Levels of bisphenol A (BPA) in amounts shown to cause health problems in laboratory animals are present in most canned food, according to a new study released by The National Work Group for Safe Markets, a coalition of public health and environmental health groups.
The study, No Silver Lining, tested food from 50 cans from 19 U.S. states and one Canadian province for BPA contamination.
Over 90 percent of the cans tested had detectable levels of BPA, some at higher levels than have been detected in previous studies.
BPA is a widely used chemical in the container industry. It has properties that make plastic bottles more rigid and is also present in plastic liners of tin cans. The study said it tested canned fish, fruits, vegetables, beans, soups and tomato products.
One can of DelMonte green beans had the highest levels of BPA ever found in canned food, at 1,140 parts per billion, the report said.
While the Food and Drug Administration says current levels of BPA found in plastic containers are not harmful, some health advocates take a different view, pointing to studies suggesting the chemical ends up in the products within the containers.
In Washington, Sen. Diane Feinstein (D-CA) embraced the report, saying it demonstrates that too much of the chemical ends up in food and beverages. She says exposure to even low doses of BPA, a synthetic sex hormone, has been linked to cancer, abnormal behavior, diabetes and heart disease, infertility, developmental and reproductive harm, and obesity.
Bill would ban BPA
Feinstein has introduced legislation that would ban BPA in cans, in addition to other food and beverage containers. The Senator said she is hopeful that the Food Safety Act will include language that protects consumers from BPA exposure.
"I was pregnant with my second child at the time of this study, and I hate to think I exposed her to BPA through the canned foods I ate, especially when there is evidence that even small amounts of this chemical can cross the placenta and impact prenatal development," said Bobbi Chase Wilding of Clean New York, report co-author.
Dr. George Lundgren, a family physician, was biomonitored and discovered BPA in his own body.
"Diabetes and obesity are increasing at such a rate in my own practice that diet and lack of exercise alone can't explain it away," Lundgren said. "The fact that there is no labeling on products that expose us to a chemical that may be linked to serious health problems is disturbing."
In the last two years many retailers have stopped selling some products, such as infant formula bottles, containing BPA. Now there are signs some manufacturers are following suit.
"General Mills announced it is removing BPA from its organic tomatoes' cans, so we know that companies that want to do the right thing, but we need the FDA to commit to an outright ban protect consumers," said Mike Schade, from Center for Health, Environment & Justice, also a co-author.
Taking issue
But the packaging industry is taking issue with the report.
"We are extremely disappointed that in their zeal to educate consumers, the workgroup pursued a clear agenda. In doing so, it failed to provide readers with the full story on BPA in canned foods," said Dr. John Rost, chairman of the North American Metal Packaging Alliance Inc.
Rost said the plastic coatings of cans, which contain BPA, provide an important protection against foodborne illness and, as yet, there is no substitute.
