An FDA-certified lab in San Francisco evaluated the concentrations of BPA in the food within the cans, with some upsetting results: BPA was found in 92% of the canned food samples. Now the National Workgroup for Safe Markets has come out with a report (PDF) claiming that canned foods, many of which are labeled as "healthy" or organic, contain an average of 77 parts per billion (ppb) of BPA. NWSM reports: 
 
 The highest level of BPA—1,140 part per billion (ppb), to our knowledge the highest level ever found in the U.S.—was detected in DelMonte French Style Green Beans from a participant’s pantry in Wisconsin. Other high scorers included Walmart's Great Value Green Peas from a store in Kentucky, and Healthy Choice Old Fashioned Chicken Noodle Soup from a pantry in Montana, according to researchers from the coalition of more than 17 public and environmental health organizations. The unopened cans of fruits, vegetables, beans, soups, tomato products, sodas and milk were sent to Anresco Laboratories to determine the concentrations of BPA in the food within the can. This study also shows that BPA levels in canned food cannot be predicted by the price of the product, the quality or relative nutrition value of the product, or where it was purchased.
– Beware those innocent-looking green beans and that mom-approved chicken noodle soup! Turns out not only plastic but canned goods—because of the coating used to protect food from corrosion and bacteria—contain disturbing levels of bisphenol A, a known carcinogen. A National Workgroup for Safe Markets test of 50 cans of fruit, vegetables, soup, beans, sodas, and milk from pantries all over the country found five times as much BPA as a similar FDA test in 1997, reports Fast Company. The chemical was present in 92% of the cans, tested by an FDA-approved lab, and the level of BPA didn't reflect age or price of the product. "It takes as little as one serving of canned foods to expose a person to levels of BPA that have been shown to cause harm in laboratory animals," one of the co-authors of the study tells AOL News, warning that it's especially dangerous for pregnant women, "because fetuses are especially vulnerable to BPA's effects."
