The chemical Bisphenol A, also called BPA, has been used to make lightweight, hard plastics and epoxy resins since the 1960s. BPA may be found in many food and beverage packaging including baby bottles, infant feeding cups, water bottles, plastic dinnerware, toys, and other products. The epoxy resins are used in the inside lining of metal food cans, bottle tops, floorings, paints, and water supply pipes. In general, plastic products made with BPA will have a #7 recycling symbol on them or contain the letters “PC” near the recycling symbol. Although many studies have shown BPA to be safe, some recent studies have reported subtle effects of low doses of BPA in laboratory animals. It has not been proven that BPA is harmful to adults or children, but certain precautions have been recommended while research continues. These precautions include not using scratched baby bottles and infant feeding cups and not using BPA containers to heat food.
