This suggestion, which is sometimes referenced in poorly researched media articles, is a very dangerous one. It wrongly indicates that there are equally well-suited, well-tested, well-understood and technically viable alternatives to just replace one material with another. This is not the case. Extensive toxicological safety studies have to be done, independent authorities have to assess, producers and food companies have to test the behaviour of the material in their processes, in the packaging, over a realistic period of product life, and under varying use scenarios. As the Swiss Health authority stated: "A ban on BPA would inevitably cause manufactures of packaging and consumer products (food contact materials) to have to switch to other substances, the toxicity of which is less well known. This would mean a well characterized risk would be replaced with a conspicuously unpredictable risk.”
