Campbell Soup is planning to eliminate the use of hazardous chemical Bisphenol A (BPA) in cans that are intended for use in food and beverage packaging.
The company started replacing BPA linings with linings made from acrylic or polyester materials.
Campbell’s portfolio in cans with new linings will be introduced across the US and Canada by mid-2017.
The company tested several alternatives such as identifying linings that will ensure the safety of more than 600 different recipes, including tomato-based products, which are naturally acidic and can react with some linings over time.
It is testing alternatives to BPA coatings used on other packaging, including aluminum cans used for V8 beverages and metal screw top lids on glass jars.
Campbell Soup packaging senior program manager Mike Mulshine said: "Our priority throughout this transition has been, and will continue to be, food safety.
"We have tested and conducted trials with hundreds of alternatives to BPA lining, and believe the acrylic and polyester options will ensure our food remains safe, affordable and tastes great."
BPA is a synthetic estrogen that is used in epoxy linings to coat the inside of canned foods and beverages. It has been linked to cancer, obesity, diabetes, infertility, hormone disruption and early puberty in children.
Studies support the use of low amounts of BPA, while others contend that low amounts may be even more harmful, news.com.au reported.
More than 75% of Campbell’s soup portfolio are planned to be packed in non-BPA lined cans by December this year.
The products to be packed in new non-BPA lined cans include Campbell’s gravies, Swanson broth and SpaghettiOs pasta.
Following consumer feedback, the firm announced its plan to eliminate BPA linings in cans in February 2012 and assessed several alternatives.
However, the transition plan was delayed due to certain technical challenges and financial priorities.
