Does BPA migrate from polycarbonate plastic food and drink containers into the food?
Generally, with any kind of material, be it wood, glass, metal, plastics, migration of certain substances can be measured, especially with today´s highly sensitive analytics methods. The important question is what and how much migrates, whether this can have adverse effects, and whether these questions were properly studied. As for Bisphenol A,during the production of polycarbonate plastic, bisphenol A (BPA) is firmly bound into the polymeric structure of the plastic. While there is some potential for extremely small amounts of BPA to migrate from polycarbonate plastic, the level is far below safety based upper limits set by government bodies such as the European Union's Food Safety Authority (EFSA). Exposure to trace amounts of BPA poses no known health risk. In fact, the human body rapidly metabolises and excretes small amounts of BPA with no health effects. Regulatory agencies in Europe, the U.S. and Japan all authorise BPA and thus the use of polycarbonate plastic in applications that come in direct contact with food.
