All plastic lids manufactured for use with PYREX(R) glass bakeware, prepware and storage dishes are 100% free of bisphenol A (BPA), it was announced by Rosemont,Illinois-based World Kitchen,LLC, which is licensed byCorning Incorporated, Corning, New York, to manufacture and distribute PYREX products in North America. All PYREX plastic lids are made from a proprietary elastomer compound that is free of BPA, a chemical compound that was the subject of a recent risk assessment by Health Canada.
