A national report has found the chemical BPA in the lids and linings of canned foods across the country, according to KWG-TV in Portland, Ore.
It also found some questionable BPA substitutes that could also be leaching into food.
The study was done by environmental health groups, including the Oregon Environmental Council. The group purchased 14 cans at two different grocery stores in Portland.
Tests found BPA in eight of the 14 cans.
Bisphenol A (BPA) is used to help protect and preserve the food inside the can, but in animal studies the chemical has been linked to health problems.
In 2011, Multnomah County made it illegal to sell plastic drink containers, including baby bottles, that contain BPA.
"We know that it's linked to birth defects... infertility and breast cancer," said Jen Coleman, Health Outreach Director for the Oregon Environmental Council.
