PORTLAND, Maine (AP) - A Maine supermarket corporation is executing new restrictions on the use of chemical products and packaging deemed hazardous by some environmental health groups.

Ahold Delhaize says its U.S. subsidiaries will work with suppliers to meet standards higher than what is required by law and collaborate to address causes of contaminants. The company operates Food Lion, Giant Food, Giant/Martin’s, Hannaford, Peapod and Stop & Shop.

The “chemicals of concern” outlined in the policy include per- and polyfluoroalkyl substances (PFAS), bisphenol A (BPA) and phthalates.

The Portland Press Herald reports these chemicals are still allowed under U.S. Food and Drug Administration rules; environmental health experts say there’s evidence the chemicals can contribute to chronic health issues.
