(SAN FRANCISCO) -- An advocacy group committed to exposing and eliminating environmental risks for breast cancer has taken aim at canned foods popular among kids, reheating the debate on bisphenol A.
A new report from the Breast Cancer Fund reveals 12 canned soups and pastas found to contain BPA -- an estrogen-like chemical -- raising concern among experts for its potential health effects in children, infants and fetuses.
Topping the list was Campbell's Disney Princess Cool Shapes with 148 parts per billion. The average level across all 12 cans was 49 parts per billion.
"The findings of this report outline the urgent need to remove BPA from food packaging -- a major source of exposure to this toxic hormone disruptor -- especially in foods marketed to children," the report states.
BPA, a key ingredient in hard plastics and resins used to coat metal cans, made headlines in 2008 when it was shown to leach out of plastic when heated. The Canadian government responded by banning the chemical from baby bottles. In the United States, the federal government has not followed suit, but several local governments have and leading U.S. baby bottle manufacturers went BPA-free voluntarily. But the chemical continues to line the country's cans.
"I think they're definitely right in trying to get this chemical out of canned foods," said Dr. John Spangler, professor of family and community medicine at Wake Forest School of Medicine. "We can't do anything about past exposures but we can do something about current exposures."
When it comes to the health effects of BPA, the jury's still out, according to the World Health Organization. Laboratory studies in cells and animals have linked the chemical to cancer, infertility, diabetes and obesity. But the consequences of chronic exposure in humans remain unclear. Nevertheless, many experts and parents err on the side of caution.
"There are things we can do to minimize our exposure to BPA," Spangler said. "We can use fresh or dried pasta and sauce in jars. We can eat more fresh fruits and vegetables and fewer canned foods."
Spangler said he hopes the Breast Cancer Fund report persuades canned food manufacturers to look for alternatives to BPA.
But Campbell Soup Company spokesman Anthony Sanzio said the company is confident in the safety of its products.
"The overwhelming weight of scientific evidence shows that the use of BPA in can lining poses no threat to human health," he said. "That being said, we understand that consumers may have concerns about it. We're very aware of the debate and we're watching it intently."
