BPA (bisphenol A) is an industrial chemical used in the production of certain plastics and epoxy resins and is relevant to food-contact safety because it can occur in materials used with food and beverages.
BPA has been used in materials such as polycarbonate plastics and epoxy-based coatings, including some applications involving food and beverage containers. Small amounts can migrate from some materials into food or beverages under certain conditions.
BPA has been extensively studied because of its biological activity and potential health effects. Regulatory conclusions and permitted uses have differed across jurisdictions and have changed as scientific evidence and regulatory assessments have evolved.
