"Major U.S. foodmakers are quietly investigating how to rid their containers of Bisphenol A, a chemical under scrutiny by federal regulators concerned about links to a range of health problems, including reproductive disorders and cancer.
But they are discovering how complicated it is to remove the chemical, which is in the epoxy linings of nearly every metal can on supermarket shelves and leaches into foods such as soup, liquid baby formula and soda. It is a goal that is taking years to reach, costing millions and proving surprisingly elusive.
Randy Hartnell, whose company, Vital Choice, sells products aimed at health-conscious consumers, switched last year to can linings made without BPA. It was a costly move that he figured would resonate in the niche market that buys his canned wild salmon and low-mercury tuna."
